| Cron not sending email, command line email works Posted: 18 Jan 2022 02:12 AM PST I have installed ssmtp on an raspberry pi running Raspbian 10 Buster. Email from the command line, e.g. using mail works fine. However, I have also configured a user's cron job to send email by adding the MAILTO variable to the file. # Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any'). # # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). MAILTO="person1@myredacteddomain.tld,person2@myredacteddomain.tld" # we need to set the user path to add the system scripts directory /usr/local/sbin # I tried with PATH=$PATH:/usr/local/sbin but it used this verbatim in the path PATH=/usr/sbin:/usr/bin:/bin:/usr/local/sbin: # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # For more information see the manual pages of crontab(5) and cron(8) # # m h dom mon dow command 26 3 * * * cronic python3 ~/redacted_directory_name/redacted_script_name.py 50 16 * * * echo "Testing cron email" > ~/cron_email_test.txt
as I understand from other online searches (correct me if I'm wrong), cron uses sendmail by default to send emails. Sendmail is available on the system, but it is really ssmtp $ which sendmail /usr/sbin/sendmail $ ls -l /usr/sbin/sendmail lrwxrwxrwx 1 root root 5 Jul 20 2014 /usr/sbin/sendmail -> ssmtp
On this machine I have configured ssmtp to use an external SMTP server to send mail. cron doesn't send email either for root or another non-sudo user. So, why is cron not sending email, and how can I fix it? |
| Upgrading opensnitch fails Posted: 18 Jan 2022 01:51 AM PST I had never have problem with opensnitch.

| Cgroup and process memory statistics mismatch Posted: 18 Jan 2022 01:38 AM PST I am trying to set up some monitoring to see when a service is using too much memory. The memory usage can be read from two places: - the
/proc/<pid>/status for the pid, or - the
/sys/fs/cgroup/<group-id>/memory.stat for the control group it runs in. The service is started by systemd, so it gets its own control group, and because it sometimes starts child processes that I need to include in the statistics, and because the path is constant across restarts, the control group statistic is more appropriate. Unfortunately the numbers don't seem to match. Here is a sample of the values at a point when no subprocesses are running (the command is exactly as executed except for the service name, and the result is exactly as obtain except non-memory-related items removed): # cat /sys/fs/cgroup/system.slice/some.service/memory.stat /proc/$(cat /sys/fs/cgroup/system.slice/some.service/cgroup.procs)/status anon 5873664 file 2408448 kernel_stack 491520 slab 962560 sock 0 shmem 61440 file_mapped 405504 file_dirty 0 file_writeback 0 inactive_anon 0 active_anon 5853184 inactive_file 1916928 active_file 360448 unevictable 0 slab_reclaimable 270336 slab_unreclaimable 692224 pgfault 60258 pgmajfault 99 pgrefill 0 pgscan 0 pgsteal 0 pgactivate 0 pgdeactivate 0 pglazyfree 0 pglazyfreed 0 workingset_refault 0 workingset_activate 0 workingset_nodereclaim 0 … VmPeak: 494812 kB VmSize: 494164 kB VmLck: 0 kB VmPin: 0 kB VmHWM: 25836 kB VmRSS: 25484 kB RssAnon: 5468 kB RssFile: 20016 kB RssShmem: 0 kB VmData: 464776 kB VmStk: 132 kB VmExe: 180 kB VmLib: 23940 kB VmPTE: 156 kB VmSwap: 0 kB voluntary_ctxt_switches: 9 nonvoluntary_ctxt_switches: 620
I would consider the appropriate value to be VmRSS (= RssAnon + RssFile + RssShmem) from the process statistic. But while I would think that anon of the group should be RssAnon of the process and file of the group should be RssFile of the process, they don't match. While anon is 5736 KB, RssAnon is only 5468 KB, and for file the difference is even bigger, with file being only 2352 KB, but RssFile being 20016 KB, almost order of magnitude difference. Also there is memory.current file with one value that approximately matches anon + file + kernel_stack + slab + sock + shmem, but I don't see any matching value in the process status. So why are the numbers so different, and which are more indicative of how much memory pressure the application is exerting on the system? Note: using cgroup2 on kernel 4.19.72 (slightly stale embedded BSP). |
| Problem adding Android Bliss OS to GRUB Posted: 18 Jan 2022 03:00 AM PST Here's what's going on: I have an ACER laptop and it has Linux Mint, Ubuntu, Windows. It had an old Linux Mint Sarah partition that I reformatted into NTFS for a Bliss OS installation. I went through with the installation on the partition and launched it once it was finished, all is well. After rebooting the computer, I don't see it in the GRUB menu. Okay, that happened before with other installations and I update-grub. Reboot again and nothing. I went into boot order because sometimes the partition might show there but there is nothing. Next time I go to reinstall it shows that the partition /dev/sda7 has the Android installed. When I go into the disk utility on my Mint it also says the partition has android. How do I add it to the GRUB menu and generally access it? (Also: Secure Boot is disabled in the Setup) |

| How to make zsh autocomplete suggest flags of the inner executable of a wrapper? Posted: 18 Jan 2022 12:16 AM PST I'm using Arch Linux with zsh. I'm using devour as a wrapper for other commands, using it like devour cmd args.... I want zsh autocomplete to suggest cmd's flags/arguments after I've typed out cmd, making devour's autocomplete similar to sudo but without flags for devour. For example, typing devour id <TAB> should suggest flags for id. I've checked /usr/share/zsh/functions/Completion/Unix/_sudo but I don't know much about zsh scripting for autocomplete so I don't know what I should extract from it to get the desired behavior. How can I create an autocomplete script for such a wrapper? |
| Touchpad is only working when entered bios setup during startup Posted: 18 Jan 2022 01:45 AM PST I am trying to figure out what may be the cause that a touchpad on my hp notebook is working only if I enter bios setup (whether by pressing esc at startup or from grub) and by adding i8042.nopnp to the kernel command line. Both operations are necessary since merely adding i8042 parameter does make the touchpad discoverable but unresponsive and just entering the setup does not make anything to my knowledge. Multiple solutions that I have found (most notably adding other i8042.xxx parameters) gave no positive results whatsoever (literally, neither xinput nor dmesg outputs have not changed). By bios setup I mean a dialog where I can choose whether to open bios settings, change boot order, boot from network, launch UEFI diagnostics tool etc. My notebook's model is HP 15s-eq1017nw with a mobile Ryzen APU (4500U if it matters), no discrete GPU. The firmware versions I have tested multiple distros on (specifically: Ubuntu 21.10 and 20.04 LTS, Linux MX 21 both "ahs" and standard, and the current Manjaro ) are F.34 Rev.A and F.54 Rev.A. Before going into dmesg and xinput outputs I would like to emphasize that I have found my "solution" by a mere coincidence so there is no know-how behind it. Just for the record, bluetooth, wifi, keyboard and the display have worked out of the box. It is just the touchpad that is tricky. dmesg output when the touchpad is working (i.e. when I add i8042.nopnp to the kernel options and enter the bios setup): https://pastebin.com/ZHu1iSp4
dmesg output when I just add the i8042.nopnp but skip entering the bios setup: https://pastebin.com/mxWX9CpL
Both outputs were made just after logining in. The touchpad is recognized (both on Windows 10 and on Linux) as as Elantech touchpad: (xinput when it is working) ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN071A:00 04F3:30FD Touchpad id=10 [slave pointer (2)] ⎜ ↳ ETPS/2 Elantech Touchpad id=12 [slave pointer (2)] ⎜ ↳ ELAN071A:00 04F3:30FD Mouse id=9 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ HP TrueVision HD Camera: HP Tru id=8 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ HP WMI hotkeys id=13 [slave keyboard (3)] ↳ ACPI Virtual Keyboard Device id=14 [slave keyboard (3)]
(xinput when the touchpad is detected but it does not move the cursor, i.e. when I don't enter the bios setup) ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ETPS/2 Elantech Touchpad id=10 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ HP TrueVision HD Camera: HP Tru id=8 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)] ↳ ACPI Virtual Keyboard Device id=11 [slave keyboard (3)] ↳ HP WMI hotkeys id=12 [slave keyboard (3)]
Update 1 I just checked what does grub do when it enters the startup menu (this is what I called bios setup earlier) and it invokes the fwsetup command (or whatever it is). I wonder what happens when a machine enters this menu/state since this action makes touchpad not only discoverable but also working. And before anyone asks, waiting before launching Linux does solve the issue. |
| connected to wifi no internet Posted: 18 Jan 2022 12:14 AM PST Background: Wifi was working for months. My computer semi froze (most of the programs I was running were killed and my file manager was glitching out) The termimal worked fine so I rebooted my pc from there (sudo reboot). Logging in took way waaaay longer than usual (30s+ more than usual) and I couldn't access internet anymore. Updated kernel somewhere in december of last year. Have rebooted a few time since. What have I tried: - phone on same wifi works fine
- I rebooted my pc a couple of times
- tried to connect using mobile hotspot. Pc connects to network but still no internet
ping -c 3 8.8.8.8 gives 3 packets transmitted, 0 received, 100% packet loss (same thing with mobile hotspot) Relevant logs: Pastebin lspci 03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.

Final edit: thank you so so much!!! It turns out my firewall rules somehow got messed up? Even though I hadn't touched them in years. I just turned them off completely. |

| Automatic time synchronization: `ntpdate` works but `chrony` does not Posted: 18 Jan 2022 02:56 AM PST I have a problem with time synchronization of my Linux server. Both this machine and the NTP server are located in a (smaller) university data center hence the local address. What is strange is that the ntpdate command works: ntpdate -u 172.16.0.25
with the output: 17 Jan 15:03:53 ntpdate[25993]: adjust time server 172.16.0.25 offset 0.036043 sec
However, the chronyd does not (it simply hangs): chronyd -q 'server 172.16.0.25 iburst'
I was trying all things to set the automatic time sync using ntpd but did not succeed and finally resorted to chrony but still cannot figure it out. Here's what happened with ntpd. I installed ntpdate using the instructions on https://vitux.com/how-to-setup-ntp-server-and-client-on-debian-10. The conf file has a command server 172.16.0.25 prefer iburst
while the system status ntp reports Jan 18 10:26:11 akulab1 ntpd[26957]: kernel reports active service TIME_ERROR: 0x41: Clock Unsynchronized
The ntpq -p has the following output HKS-SRV01.unica .LOCL. 1 u 9 64 15 0.557 2275.65 9.515 –
However, after a while the service reports Jan 18 10:31:01 akulab1 ntpd[26957]: ntpd exiting on signal 15 (Terminated) as NTP sync did not succeed. But, the ntpdate -u 172.16.0.25 reports synchronization: 18 Jan 10:33:13 ntpdate[26990]: step time server 172.16.0.25 offset 2.282101 sec (if I am not mistaken...) – ksonofre 7 mins ago Here is my /etc/ntp.conf file: driftfile /var/lib/ntp/ntp.drift leapfile /usr/share/zoneinfo/leap-seconds.list statistics loopstats peerstats clockstats filegen loopstats file loopstats type day enable filegen peerstats file peerstats type day enable filegen clockstats file clockstats type day enable server 172.16.0.25 prefer iburst restrict -4 default kod notrap nomodify nopeer noquery limited restrict -6 default kod notrap nomodify nopeer noquery limited restrict 127.0.0.1 restrict ::1 restrict source notrap nomodify noquery
I have restarted the NTP service again: systemctl restart ntp The output of the ntpq -np is the following: root@akulab1:~# ntpq -np remote refid st t when poll reach delay offset jitter ============================================================================== 172.16.0.25 .LOCL. 1 u 63 64 377 0.518 104.685 14.815
However, the service (systemctl status ntp) still reports: Jan 18 11:04:10 akulab1 ntpd[27089]: kernel reports TIME_ERROR: 0x4041: Clock Unsynchronized
And, after I set the timedatectl set-ntp true the NTP service simply shuts down, i.e. reports inactive.
The last option is to simply make a cron job with the above ntpdate -u 172.16.0.25 but I would like to use a more elegant solution. Thanks a bunch in advance! |

I also tried the following xorg.conf (as well as a few different alterations, like disabling Accel) with and without xf86-video-intel, but it doesn't seem to help (found at https://bbs.archlinux.org/viewtopic.php?id=208252): Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection
I tried booting a Linux Mint live USB and everything works fine. I can launch the desktop environment, watch videos etc. without any issues. It also came pre-installed with Windows and Windows worked fine as well. Since I bought the PC second hand I ran all the bios diagnostics (for unrelated reasons) just to check that it's all okay and all tests passed as well. I also tried switching to linux-lts and that made no difference either :( I've spent quite some time looking into this issue and haven't been able to figure it out. Any help is really appreciated :) |
| Resolving broken unmet dependency with libc6 on mint 20.2 Posted: 18 Jan 2022 03:34 AM PST I work at a university where I am forced into the Microsoft ecosystem. Ugh. Given that reality, I'd like to install the linux OneDrive client. https://github.com/abraunegg/onedrive I am getting the following error and I can't resolve it. $ sudo apt install onedrive Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

If you wonder about the one non-upgraded package, its snapd: $ sudo apt-cache policy | tail <omitted stuff> Pinned packages: snapd -> 2.51.1+20.04ubuntu2 with priority -10 snapd -> 2.49.2+20.04 with priority -10 snapd -> 2.48.3+20.04 with priority -10 snapd -> 2.44.3+20.04 with priority -10
I get that I have 2.31-0ubuntu9.2 installed. $ sudo apt-cache policy libc6 libc6: Installed: 2.31-0ubuntu9.2 Candidate: 2.31-0ubuntu9.2 Version table: *** 2.31-0ubuntu9.2 500 500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 100 /var/lib/dpkg/status 2.31-0ubuntu9 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages
And I get that in need a more recent version of libc6. I assume that my current version of libc6 is included in 2.31-0ubuntu9.2 Two questions: Why does apt report `2.31-0ubuntu9.2 is to be installed." It seems to me it's already installed. What how can I resolve this issue? (Or do I just live with inefficient access to OneDrive by browser or running a virtual Windoze machine) I'm sure I could dig around and find a way to upgrade libc6, but I'm wondering whether that's wise, given that it's a pretty foundational library. Thanks for any information you can provide. I especially appreciate explanations of suggested solutions so I can continue to learn to effectively manage my computer. |
| How to screen share using slack and wayland in Manjaro Gnome? Posted: 18 Jan 2022 03:16 AM PST On Manjaro, I have installed com.slack.Slack in version 4.23.0 through flatpak. Now, when I try to share a screen, I unexpectedly get a "Screen Share" popup that appears to be coming from Gnome. I expect to not see that at all but that I can select the app / screen directly from the underlaying slack Share Screen popup. 
The additional Screen Share popup would be fine, yet it also does not react on clicks. I cannot Cancel, Share and cannot even a select a screen nor an entire screen. How to properly enable screen share? |
| Is it possible to show when an executable was run for the last time? Posted: 17 Jan 2022 11:47 PM PST Note that the FS is mounted with the relatime option (thus the recent last access time is not shown). Is there a way to see when an executable (ELF 64-bit LSB executable) was run for the last time? Using root access. The idea is that a complex production application can run the same exec that currently exists at two different places (pending installation). I just want to ensure that only one of them is run from now on, without interrupting anything (cannot temporarily remove one for instance ; it's 99% sure only one of them is used, but need to be 100% sure). |
| Merge every two lines after the pattern until next pattern Posted: 18 Jan 2022 01:18 AM PST File.txt String1? word1 word2 word3 word4 String2? word5 word6 word7 word8
Desired Output: String1? word1 | word2 word3 | word4 String2? word5 | word6 word7 | word8
Only pattern is Lines with /?$/ I tried: sed '/\?$/{n;:l N;/\?$/b; :a; N; $!b a; s/\n\s\{1,\}/ | /g; bl}'

... but it's a work-around and is extremely slow. Can anyone help with a single one liner without pipes and is a fast solution? If an empty line doesn't exist, as in pattern ,$\|^$, and if ^$ is not there and is having another line with ?$, then how can we hold the buffer from ?$ to first non-greedy ?$ pattern and then print all lines except the last line and merge the last line with the next pattern buffer for search? |
| mail command sends body as attachment, unlike normal email client? How to stop this? Posted: 17 Jan 2022 11:53 PM PST I am using the mail command from mailutils on Ubuntu Linux 20.04. I am using it to send documents automatically to a service on the web which processes them. They provide an email address to which you can forward your document as an attachment. When I use my normal email client, say, thunderbird, or SOGO mail, and manually send a document it works fine, and the document is received as expected and processed. However, when I use the mail command like this: echo "The body of the email" | mail -s "just a test" someone@service.com -A my_attachment.pdf
the remote service acts as though it has received two documents, the actual attachment, and also the body of the email as another attachment. This makes me think the mail command somehow sends the body as an attachment or something in a different way to other email programs I use. The emails from mail look fine in my own email client. So how do I get my emails from mail to look like they only have one attachment, just like my manual emails? If not possible is there an alternative command line email program on Ubuntu which will act in the way I want? |
| Installing CUDA Toolkit (11.5) on Debian (11) Posted: 18 Jan 2022 12:51 AM PST The instructions to install CUDA Toolkit (11.5) on Debian (11) are nicely organized here: developer.nvidia.com/cuda-downloads. But I seem to run in a small dependency issue, whether I try the deb (local) method or deb (network) method. My impression is that apt wants to install the 470 versions of nvidia related packages, whereas it should install the 495 versions. If I run sudo apt install cuda then I obtain: Reading package lists... Done Building dependency tree... Done Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: cuda-drivers-495 : Depends: nvidia-driver (>= 495.29.05) but it is not going to be installed Depends: libcuda1 (>= 495.29.05) but it is not going to be installed Depends: libnvcuvid1 (>= 495.29.05) but it is not going to be installed Depends: libnvidia-allocator1 (>= 495.29.05) but 470.74-1 is to be installed Depends: libnvidia-compiler (>= 495.29.05) but 470.74-1 is to be installed Depends: libnvidia-encode1 (>= 495.29.05) but it is not going to be installed Depends: libnvidia-fbc1 (>= 495.29.05) but it is not going to be installed Depends: libnvidia-opticalflow1 (>= 495.29.05) but it is not going to be installed Depends: libnvidia-ptxjitcompiler1 (>= 495.29.05) but 470.74-1 is to be installed Depends: libnvoptix1 (>= 495.29.05) but it is not going to be installed Depends: libxnvctrl-dev (>= 495.29.05) but it is not going to be installed Depends: nvidia-cuda-mps (>= 495.29.05) but 470.74-1 is to be installed Depends: nvidia-detect (>= 495.29.05) but 470.74-1 is to be installed Depends: nvidia-libopencl1 (>= 495.29.05) but 470.74-1 is to be installed Depends: nvidia-opencl-common (>= 495.29.05) Depends: nvidia-opencl-icd (>= 495.29.05) but it is not going to be installed Depends: nvidia-smi (>= 495.29.05) but it is not going to be installed Depends: nvidia-xconfig (>= 495.29.05) but 470.57.02-1 is to be installed Depends: nvidia-modprobe (>= 495.29.05) libcufile-11-5 : Depends: liburcu6 but it is not installable nvidia-libopencl1 : Conflicts: libopencl1 Conflicts: libopencl1:i386 Recommends: nvidia-opencl-icd but it is not going to be installed or opencl-icd ocl-icd-libopencl1 : Conflicts: libopencl1 ocl-icd-libopencl1:i386 : Conflicts: libopencl1 E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
I managed to install some dependencies by specifying the version manually, e.g. sudo apt install nvidia-settings=495.29.05-1 but this seems like an endless process. Note: If I run sudo apt-cache policy nvidia-driver then I obtain: nvidia-driver: Installed: (none) Candidate: 470.74-1 Version table: 495.29.05-1 500 500 https://developer.download.nvidia.com/compute/cuda/repos/debian11/x86_64 Packages 500 file:/var/cuda-repo-debian11-11-5-local Packages 470.74-1 990 990 http://deb.debian.org/debian testing/non-free amd64 Packages
Does anyone know how I should proceed? At the moment my /etc/apt/sources.list is as follows: deb https://developer.download.nvidia.com/compute/cuda/repos/debian11/x86_64/ / # deb-src https://developer.download.nvidia.com/compute/cuda/repos/debian11/x86_64/ / deb http://deb.debian.org/debian/ bookworm contrib deb http://deb.debian.org/debian/ testing main contrib non-free
PS: I also tried the "runfile (local)" method, but after running sudo sh cuda_11.5.0_495.29.05_linux.run and selecting the components to install, I get "Installation failed" with no further details. |
| Simultaneous digital and analog output on pipewire Posted: 18 Jan 2022 03:00 AM PST i'm currently trying to configure pipewire to use both digital and analog output at the same time with different streams, like in windows. In pavucontrol currently i have to switch between "analog duplex" and "Digital stereo (IEC958) output + analog stereo input", this is not good especially when using pulseEffect, it causes all sorts of troubles when switching. I have an x570 aorus master with a Realtek ALC1220-VB and on majaro is using Starship/Matisse HD audio controller Thanks. Edit: apparently using the pro audio profile did what i wanted for the output but now the analog input doesn't work: the two neither one of the two interfaces can retrieve any sound from the mic and the first one it doesn't have volume meter bar. |

| pam_lastlog does not write to /var/log/lastlog Posted: 18 Jan 2022 02:48 AM PST I am using pamela with JupyterHub to open PAM sessions for my users. I am on CentOS 8 and I am using the login service. I can see in /var/log/secure pam_unix(login:session): session opened for user testuser by (uid=0) and in /var/log/messages systemd[1]: Started Session 8341 of user testuser Furthermore there are no erros logged in /var/log/{messages|secure|audit/audit.log}. But with a new user succesfull logged in to JupyterHub, the lastlog command still says that this user has never logged in. So I think I miss some requirements for pam_lastlog in order to write information to /var/log/lastlog. pam_open_session is called in a subprocess with root privileges. Maybe this subprocess needs to be tied to a pts or tty in order to write useful information to /var/log/lastlog? This is the /etc/pamd.d/login file: #%PAM-1.0 auth substack system-auth auth include postlogin account required pam_nologin.so account include system-auth password include system-auth # pam_selinux.so close should be the first session rule session required pam_selinux.so close session required pam_loginuid.so session optional pam_console.so # pam_selinux.so open should only be followed by sessions to be executed in the user context session required pam_selinux.so open session required pam_namespace.so session optional pam_keyinit.so force revoke session include system-auth session include postlogin -session optional pam_ck_connector.so

| Setting environment variable using shell script Posted: 18 Jan 2022 12:01 AM PST I am using csh scripts for some automation purpose. I have a number of scripts, and the beginning of all of which I need to set a fixed set of environment variables. |----SCRIPT 1---| |----SCRIPT 2---| |# set env vars | |# set env vars | | | | | |# do something | |# do something | | | |# else |
So I thought that I'll put all the environment variables in another script and source it from each file. But as it turns out, environment variables set inside the sourced script are not reflected outside. Is there any clean way to achieve what I want? Or do I have to explicitly set environment variables in each script ? UPDATE : While sourcing the file, I was piping the output to a file using the 'tee' command. I noticed that after removing the pipe, the script file worked. |
| "Press ENTER or type command to continue": why am I seeing this? Posted: 18 Jan 2022 03:03 AM PST I'm familiar with this message when a command's output is more than one line. However, on one of the systems I use, I see it every time I write with :w, despite having plenty of horizontal space for the message. For example: 
This only seems to happen when I use vim in a tmux session, but I can't work out why this should happen. Every other aspect of vim and tmux seems to be working fine. Turns out it has nothing to do with tmux.
Update: I tracked it down to the following line in my vimrc: set backupdir=/tmp
Using a vimrc that contains only this line is enough to trigger the message when writing to a file. Interestingly, it only happens when I write to an existing file. Why would this happen, and on this machine only? |
