| mount: unknown filesystem type 'btrfs' Posted: 14 Nov 2021 12:25 PM PST I have a Raspberry Pi running Raspbian with a btrfs partition on an external drive. The system is configured to install security updates automatically, but not other updates. All of a sudden, upon rebooting the system, the btrfs partition no longer mounts. When I try to mount it manually, I get: mount: unknown filesystem type 'btrfs'
Some sources on the net suggested running modprobe to ensure btrfs support is installed. modprobe btrfs results in: modprobe: ERROR: could not insert 'btrfs': Exec format error
What's wrong here? What can I do to diagnose the issue and fix it? |

Also, when running ntpd in the background and using ntpq -p to query the ntpd status. We get the following result, the st, delay, offset and reach seem fine. 
However, the ntpd never select the ntp server as the time source(never show "*" or "+" before the remote address ) and sets the local time after a long time of waiting.
I looked into the source code. When using ntpdate(-q) mode the ntpd will exit after doing all bursts for every server when there is no clock selected/ set } else { peer->burst--; if (peer->burst == 0) { /* * If ntpdate mode and the clock has not been * set and all peers have completed the burst, * we declare a successful failure. */ if (mode_ntpdate) { peer_ntpdate--; if (peer_ntpdate == 0) { msyslog(LOG_NOTICE, "ntpd: no servers found"); if (!msyslog_term) printf( "ntpd: no servers found\n"); exit (0); } } } }
However, I am still not understand why ntpd didn't select and set a time form the server. Thanks for your help in advance. |
| Why a bash array remains empty if I pipe the result of a for loop, used to populate it, into zenity --progress? Posted: 14 Nov 2021 11:47 AM PST I have an array with some data: array1=( AAA BBB CCC DDD )
I want to populate an array of results from calling a certain API with the data in array1 and at the same time I want to show the progress with zenity. So I though about doing this: i=0 prog=0 for c in ${array1[@]}; do echo $prog #updates the text echo "# $c" #updates the percentage data_array[$i]=$(curl -s "https://hub.dummyapis.com/products?noofRecords=4&idStarts=1001&useless=$c" | jq .[$i].id | bc) (( prog=prog+30 )) (( i++ )) done | zenity \ --progress \ --title="Title" \ --text="Text" \ --percentage=0 \ --auto-close \ --auto-kill
The problem is that the data_array remains empty. On the other hand, it gets populated if I omit the pipe to the zenity command. If I understood correctly, it's because the pipe it's spawning a new subprocess, thus the data_array is empty there. I also tried using this sintax, but with same results: zenity \ --progress \ --title="Title" \ --text="Text" \ --percentage=0 \ --auto-close \ --auto-kill < <( for c in ${array1[@]}; do echo $prog echo "# $c" data_array[$i]=$(curl -s "https://hub.dummyapis.com/products?noofRecords=4&idStarts=1001&useless=$c" | jq .[$i].id | bc) (( prog=prog+30 )) (( i++ )) done)

| Change PDF page size without re-scaling a content (CLI) Posted: 14 Nov 2021 11:10 AM PST Question I have a PDF with a non-standard page size. I would like to change PDF canvas size to A4 without re-scaling the content. I can receive the expected result with Printing to PDF (picture below, original content is a black rectangle). However, I would like to achieve the same result using Linux CLI.  How can I change PDF page size without rescaling the content, using the Linux command line? Investigation I have tried to use pdfjam: pdfjam --outfile out.pdf --paper a4paper in.pdf. Unfortunately, it scales to fit in.pdf and thats unacceptable for me. Also I tried cpdf: cpdf -scale-page a4portrait in.pdf -o out.pdf scales content to the page size. Moreover, found PdfScale. However it can only scale content or change page size with fitting the content. The similar problem has been described here, but the author used GUI application (not CLI) |

| Does the Dell Universal Receiver work on Jetson Nano? Posted: 14 Nov 2021 10:33 AM PST According to this question on AskUbuntu, Is the Dell Universal Pairing USB receiver supported?, the Dell Universal Receiver works on PCs running Ubuntu (since at least 18.04) - apparently, only after the dongle has first been paired up with the keyboard and mouse on either a Mac or PC running Windows. Seeing as the OS used by the Jetson Nano (Linux4Tegra) is based upon Ubuntu 18.04: NVIDIA® Jetson™ Linux Driver Package (L4T) is the board support package for Jetson. It includes Linux Kernel 4.9, bootloader, NVIDIA drivers, flashing utilities, sample filesystem based on Ubuntu 18.04, and more for the Jetson platform. does that mean the Dell Universal Receiver works (assuming it has already been paired), on the Jetson Nano, or have those drivers not (yet) been ported, seeing as the Jetson Nano is based on ARM and not x64? There are reports, on the Jetson Developer forums, of the Logitech Unifying Receiver working on the Jetson Nano, see Can Jetson Nano connect with wireless keyboard and wireless mouse via usb? but no reports about the Dell receiver. However, the Dell receiver is not the same beast, nor is it a branded/repackaged dongle, so the drivers may not be the same, nor be already ported/supported. Does anyone have first hand experience of the Dell Universal Receiver up and working, on a Jetson Nano?
Note that I have already asked this question on AskUbuntu, but it was closed for not being "Ubuntu enough", i.e. Linux4Tegra isn't an officially support Ubuntu product. Hopefully it is more au point on here..? |
| How to check arguments given to a bash script efficiently? Posted: 14 Nov 2021 11:43 AM PST I wrote a bash script but since I'm a self-learner bash rookie, I wanted to ask if I can check the given arguments more efficiently. I also googled about this and checked topics here but the examples I have seen so far are too complicated. In python3, there are a lot easier methods for this but I guess in bash it is a bit more complex. #!/bin/bash ERR_MSG="You did not give the argument required" if [[ ${1?$ERR_MSG} == "a" ]]; then echo "ABC" elif [[ ${1?$ERR_MSG} == "b" ]]; then echo "123" elif [[ ${1?$ERR_MSG} == "c" ]]; then echo ".*?" else echo "You did not provide the argument correctly" exit 1 fi

| reading filenames with newlines Posted: 14 Nov 2021 10:17 AM PST Now we're all familiar with not using: find . -print | xargs cmd
but using find . -print0 | xargs -0 cmd
To cope with filenames containing e.g. newline, but what about a line I have in a script: find $@ -type f -print | while read filename
Well, I assumed it would be something like: find $@ -type f -print0 | while read -d"\0" filename
And if I'd simply done: find $@ -type f -print0 | while read filename
I'd be seeing the NULLs? But No, the while loop exits after zero times around (in both cases) I assume because the read returned zero, also I assume because it read a NULL (\0) . Feels like the bash read should sport a "-0" option. Have I misread what's happening or is there a different way to frame this? For this example I may well have to recode to use xargs but that's a whole heap of new processes I didn't want to fork. |

| How to get IP addr from MAC Posted: 14 Nov 2021 11:37 AM PST I'm trying to connect to a second-hand external wifi camera. It has an ethernet slot and a sticker with the MAC address but no other branding or model/serial numbers. I am trying to find its IP address.

| wc command with no FILE argument (reading from standard input) Posted: 14 Nov 2021 12:00 PM PST Regarding wc (word count) command... I am trying to understand the following (from man wc which I have quoted below plus added a longer quote at end of my question) With no FILE, or when FILE is -, read standard input. How exactly does this work? At what point do I type the "standard input"? Finding explanations online rather confusing. Maybe I am just missing some basic info regarding what exactly stdin is. From man wc SYNOPSIS wc [OPTION]... [FILE]... wc [OPTION]... --files0-from=F DESCRIPTION Print newline, word, and byte counts for each FILE, and a total line if more than one FILE is specified. A word is a non-zero-length sequence of characters delimited by white space. With no FILE, or when FILE is -, read standard input.

| Run command every time regex is matched, reading from stdin which does not have an EOF Posted: 14 Nov 2021 10:56 AM PST I am attempting to write a BASH script that creates a timestamp (to be written to file) every time a certain string is found within the output of dbus-monitor (parameters specified later in post). The main purpose of my script is to save the time (including milliseconds) and date whenever a song starts playing on Spotify, as it utilizes notifications. The following command outputs string "Spotify" whenever a song beings playing. dbus-monitor --session interface='org.freedesktop.Notifications',member='Notify' | grep 'string "Spotify"'

I am assuming the reason of my code's dysfunction is that dbus-monitor continuously runs, therefore preventing the while loop from executing. |

| Run shell script when Caps Lock is pressed (on Wayland) Posted: 14 Nov 2021 11:05 AM PST I'm trying to get my head around shell scripting to solve a minor Wayland/Mutter bug that hasn't been addressed in over two years. I'm completely unfamiliar with shell scripting, but I think this should be possible. The problem is that on Wayland the xkb option to indicate keyboard layouts with a LED doesn't work correctly. It works on first layout switch, turning the LED on, but then stops working, leaving the LED always on. So my idea is to have a script that would check for the contents of the system LED file upon pressing a particular key (CapsLock in my case), and change it to the opposite value. The logic would be as follows: listen to CapsLock and upon keypress do cat /sys/class/leds/input7::capslock/brightness if cat returns 0 then echo 1 > /sys/class/leds/input7::capslock/brightness if cat returns 1 then echo 0 > /sys/class/leds/input7::capslock/brightness wait for next CapsLock keypress
I'm good at learning stuff from examples, but I couldn't find relevant info online. I guess I just don't know how to phrase this correctly to get relevant results. So any tips and pointers in the right direction greatly appreciated! UPD:
I got as far as creating the shell script that switches the LED on and off depending on the current state of the LED. How do I make it execute every time CapsLock is pressed? #!/bin/bash led=`cat /sys/class/leds/input7::capslock/brightness` if [[ $led = "1" ]] then echo 0 > /sys/class/leds/input7::capslock/brightness else echo 1 > /sys/class/leds/input7::capslock/brightness fi
UPD2:
I obviously made the shell script executable, moved it to /usr/local/bin/, and added it to a file in /etc/sudoers.d/ to allow it to run without a password. UPD3
I noticed that the ìnput number in the directory structure can change between reboots, so I modified the script to account for that. #!/bin/bash led=`cat /sys/class/leds/input?::capslock/brightness` file=`ls /sys/class/leds/input?::capslock/brightness` if [[ $led = "1" ]] then echo 0 > $file else echo 1 > $file fi
Now I need to execute this every time Caps Lock is pressed. |

That means add commas after two lines till 11 lines, then again start after INSERT INTO and repeat. I tried to google and found this sed '/INSERT/{n;n;n;n;n;s/$/,/}' teststring.txt --> this will put comma on fifth line after insert. The problem is if I run it again for the sixth line
sed '/INSERT/{n;n;n;n;n;n;s/$/,/}' teststring.txt , then it replaces the earlier comma placed by the first SED command

| Annotate series of pdf documents with page counter Posted: 14 Nov 2021 10:27 AM PST The goal is to enumerate a set of .pdf files using command line tools. Ideally a free open source package would lend itself to performing the enumeration tasks on both Catalina and Ubuntu 20.04. Assume a set of files: - file1.pdf
- file2.pdf
- file3.pdf
Algorithm: - Initialize the counter to 100 only once: do not reset ever to 100
- Starting with the first page of file1.pdf:
- Enumerate (stamp) the bottom right corner with "myText [counter]"
- increment the counter and stamp the next page
- if the last page of the file has been enumerated, repeat the process with the next file until all pages of all files are enumerated. The next file shall continue using the same counter, which will NOT be reset to 100.
Solutions / examples to accomplish the goal are appreciated. CLARIFICATION: All pages shall have a unique page numbers: If each document has 10 pages, then the last page number will be 129. |

| Mute all microphons with one command Posted: 14 Nov 2021 11:01 AM PST I am running Linux Mint 19.1 and would like to assign a shortcut key to a script that mutes and unmutes my microphones. I have found many solutions that do this for a single input, e.g. amixer set Capture toggle pactl set-source-mute $source_number toggle
However, as I switch between different inputs (built in mic, bluetooth headset, wired headset), I would prefer something that consistently toggles ALL of these on/off together. This means that they are either all on or all off, no risk of one being on while another is off.
I am unsure weather or not the assigned source numbers in pactl are constant or not and would like a solution that will work reliably, independent of if I reconnect the mic 42 times or even connect a different (bluetooth) device. Is there a command to get the source used by the system (the one that same as system refers to in a number of applications, e.g. Zoom)?
If so, when I run the command/script I would like to get the state of that device and set the state of all the relevant devices to the opposite state. Any suggestions for how I can do this? |

| How to boot FreeBSD from GNU GRUB 2 bootloader command mode Posted: 14 Nov 2021 11:48 AM PST I've been following an installation guide for FreeBSD and this part seems to be skipped. When I reboot my system after the initial installation it loads to grub boot loader, but in command mode as no options have been setup yet. I have windows10 installed on another drive. How do I load FreeBSD from this command mode? |
| Is there a reason why /var/log/lastlog is a huge sparse file (1.1TB)? Posted: 14 Nov 2021 12:01 PM PST I have read some question, that ask advice how to rsync sparse files efficiently mentioning the files /var/log/lastlog and /var/log/faillog. Indeed I myself have stumpled over those files being an "issue" as their being backup via rsync turns them to become "unsparse". What I hence wonder is, what is the need/backgrounding motivation to have those files as sparse, huge files (in my case it was 1.1TB)? Also in relationship to this a follow up: Since I was assuming them to be logfiles I do not care about excesively I truncated those files, did I corrupt anything with truncating those files ? |

| How Do I Package a Django Website for Debian (Not a Python Package or Egg)? Posted: 14 Nov 2021 12:03 PM PST I have been searching for the last two weeks and chased myself into multiple dead ends trying to figure out the path that takes me where I want to go. However I finally have to admit that my answer isn't clearly posted anywhere, and here we are. I'll start off my clarifying: I don't want to build a redistributable Django "App" which seems to mean "plugin" - This isn't a python plugin, it's a full fledged website with an FCGI server, /etc/init.d script, config file in /etc/djangoapps and a requirements.txt for the plugins my site uses. I want to build a deb package to allow me to deploy to a Dev and Prod server from a build server (I'm using Bamboo, but Jenkins should be the same principle.) I also want to do this on Debian 7 Wheezy, not Ubuntu. PKGME Seems to do the job on Ubuntu and Debian 8, however it fails to install in a functional state in Wheezy, and I was unable to find a way to fix it. So I went with trying setuptools, stdeb, and debuild to create my package, which causes me to wind up with an egg, inside a deb, that does not contain any of my /etc or /usr files. So what is the proper method here? |
| Tell SSH to use a graphical prompt for key passphrase Posted: 14 Nov 2021 11:05 AM PST How can I force SSH to request passphrases using a graphical prompt (GTK, for example) instead of the standard one that uses the terminal? I tried setting SSH_ASKPASS=/usr/bin/ssh-askpass but it seems to have no effects. The problem is the fact the openssh documentation says If ssh does not have a terminal associated with it but DISPLAY and SSH_ASKPASS are set, it will execute the program specified by SSH_ASKPASS and open an X11 window to read the passphrase. An ssh launched from the command line, in my case as the result of a git push, will have a terminal associated with it, so the SSH_ASKPASS logic seems to be ignored. Please note that I am not referring to ssh-add, but to generic ssh invocations towards an hosts for which a key pair is present but protected by a passphrase. |
