| Failed to load module "pk-gtk-module" and other errors installing Maya 2022 Posted: 25 Jun 2021 11:18 AM PDT I downloaded and unzipped Autodesk Maya's Linux 64 Bit System and tried to run ./Setup file in the terminal. A GUI window with the title "Autodesk Install" appears temporarily, but then disappears and the following error messages are printed: 
I've tried a number of things but nothing seems to be working yet. Any ideas? Thanks so much!  |
| How can I send the outputs of two different commands as one email in Linux? Posted: 25 Jun 2021 10:21 AM PDT In a script, I need to send the contents of two separate Linux commands in one email. I understand that I can append the outputs of the two commands to a file and send that file as an attachment. However, the script will also be run by other users so they may not have permission to view/edit/send this files. Therefore, I was wondering if there is a way to directly send the outputs of two different commands in one email.  |
| Stripping and Renaming parent directory for each line output in tar -T -? Posted: 25 Jun 2021 09:57 AM PDT I have an list of directory output from the following command that I want to tar: find ./temp -type f -name '*'
./temp/main/randomfile.txt ./temp/main/dir_a/random.txt ./temp/main/dir_b/random.txt ./temp/main/dir_c/random.txt
Then I pipe the result: tar -zchf ./tars/randomtar.tar.gz -T - Combined commands: find ./temp -type f -name '*' | tar -zchf ./tars/randomtar.tar.gz -T - This will take each result from the output and tar into randomtar.tar.gz How do I change the parent directory of each output from find command when compressing? When I untar the file, I would get: ./temp/main/randomfile.txt ./temp/main/dir_a/random.txt ./temp/main/dir_b/random.txt ./temp/main/dir_c/random.txt
I want to get this result when I untar: ./new_parent_name_main/randomfile.txt ./new_parent_name_main/dir_a/random.txt ./new_parent_name_main/dir_b/random.txt ./new_parent_name_main/dir_c/random.txt

| No Bash Prompt after SSH login to rPI (Pi-Hole) Posted: 25 Jun 2021 10:34 AM PDT I have had an rPi serving up pi-hole DNS for some time now. The issue has existed for at this point years. I would like to be able to understand and potentially resolve without rebuild. After an OS update I no longer get a prompt when I login over SSH on any user. Authentication goes through, the prompt is blank, if I leave it there, it will eventually timeout. If I ctrl+c it will drop me to a basic bash shell. Linux blackholedns 4.19.66+ #1253 Thu Aug 15 11:37:30 BST 2019 armv6l The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright. Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law. Last login: Fri Jun 25 11:27:59 2021 from x.x.x.x
^ This is all I will see, unless I throw ctrl +c at the session. like so: Last login: Fri Jun 25 11:35:04 2021 from x.x.x.x ^C -bash-4.4$
If I whoami, its the pi user: -bash-4.4$ whoami pi
If I su to pi, it then returns to the familiar prompt and I can go about my business. -bash-4.4$ su pi Password: pi@blackholedns:~ $
For the past 2 years. I was content with just manually bypassing the issue. Now, I would like to setup syncing for a backup pi and in order to setup gravity sync. The replica pi, requires the ability to ssh into this pi. That presents the issue shown above. The session attempts to connect and eventually times out. What have I tried to fix this issue? (none of which has worked) - Set hosts entry for both systems in /etc/hosts on the troubled system.
- "UseDNS no" in sshd
- "GSSAPIAuthentication no" in sshd
- "QOS = IPQoS 0x00" in sshd
- Created a new user, ssh with this new user, has the same result. no prompt.
- Tried logging in via ssh keys instead of pw
- Attempted to restore .bashrc or .profile so I went and copied from /etc/skel the .bashrc and the .profile file back into /home/pi

| Need to set a new default path for command in Linux Posted: 25 Jun 2021 09:27 AM PDT Basically, what the title says. I'm setting up a new version of LUA and HAProxy under my user account in Redhat, so the bin directory that contains it is /home/user1/testing/usr/local/bin. I've tried adding this to the PATH in my existing .profile, and .bash_profile files, but when I use which lua, I still get the older version under /usr/bin, in the root directory. My path looks like this: echo $PATH /usr/local/bin:/usr/bin:/home/user1/testing/usr/local/bin/
Is there any way for me to do this without overwriting all the other commands?  |
| Fix too many levels of symbolic links. Linux from scratch Posted: 25 Jun 2021 09:12 AM PDT I was trying to follow the Linux from scratch book but I'm having trouble compiling glibc, I think this is related to the problem I'm having with the tools directory. On one part of the book, I was supposed to use the following command cp -rv dest/include* /tools/include but I get the following error cp: failed to access '/tools/include': Too many levels of symbolic links So, I'm having trouble with the symbolic link and I have no clue how to fix it. When I run find -L /tools >/dev/null I get the same error. If I run ls -l /tools I can see why it is failing yet I don't know what to do about it. This is what I get lrwxrwxrwx 1 root root 6 Jun 23 13:47 /tools -> /tools I'm a windows user so I don't know much about this and I would prefer an explain like I'm 5 years old answer, thank you.

| How to search for multiline text files containing a set of words (e.g., AAA & (BBB | CCC) & ~DD)? Posted: 25 Jun 2021 09:34 AM PDT I need to find the files that fulfill relatively complex condition. For example, I want to find all files that fulfill all below conditions: - does contain word AAAA
- does contain word BBB or CCCCC (may contain both of them)
- does not contain word DDD
The words may appear in any order and may appear in different lines. I have one solution, that combines find and egrep, but is not very legible. find . \( -type f -and -exec egrep -q 'BBB | CCCCC' {} \; \ -and -exec egrep -q AAAA {} \; \ -and -not -exec egrep -q DDD \) -print

| Find anywhere epoch times in milliseconds in a log and replace them to human readable time Posted: 25 Jun 2021 09:11 AM PDT I would like to find and replace all epoch times in milliseconds with human readable times. I got already a solution how to do that, if the epoch times is in the first column for example, but not randomly searching for 13 digits and replace it then with time like "23:59:59 01.01.1980" This is to be done on a Linux machine So the epoch times could be like: sms address="+********" body="This is some example text 🙄" date="1620053279300" locked="0" protocol="0" read="1" status="-1" type="1"/> or even some log some log "1602674980448" or some log some log 1602674980448 some log some log Any ideas? Thanks a lot in advance.  |
| bash to kill a process by name Posted: 25 Jun 2021 10:29 AM PDT I have these attempts to shut down processes (and childs) by name (I got both from this site and adapted them): read -p "Set process name: " PS # first option f() { ps ax | grep "$1" | grep -v grep | awk '{print $1}' | xargs kill -9; } f $PS # second option for pid in $(ps -ef | awk '/$PS/ {print $2}'); do kill -9 $pid; done # end of bash if [ $? -gt 0 ]; then echo "no process:" $PS else echo "Finished" fi
But I don't know which of the two is more effective (or none of the above) Additionally, the second loop does not complete (that is, if there are no processes, it should exit "no process:" name of process), but it goes straight to "Finished" And in both cases there is a problem with kill command. If there are no processes, a message appears indicating options on the use of kill. I can hide it with &> /dev/null or set +m, set -m but but I don't know if kill will have any flag (switch) to silence the output Update: thanks to @steeldriver I was able to see the error that awk does not accept variables (/$PS/) so i found this solution HERE: And replace this: for pid in $(ps -ef | awk '/$PS/ {print $2}'); do kill -9 $pid; done
with this: for pid in $(ps -ef | grep "$PS" | awk '{print $2}'); do kill -9 $pid; done

| Kill processes only if a specific number of PIDs match criteria Posted: 25 Jun 2021 08:12 AM PDT I am trying to improve this one liner I use as an (abused) docker-compose healthcheck that runs inside a container: ps -C program.bin -o pid,pcpu --no-headers | awk '$2 > 98 {print $1}' | xargs kill -9
In current form, I filter the PIDs with CPU utilization over 98% and kill any matching PID right away. However, I would like to kill only if an exact number of resulting PIDs have the high utilization (in other words, if one program.bin PID has CPU over 98%, don't kill it, but if 2 of them meet the criteria, kill them both). Any pointers on how to do this? Thanks!  |

| Linux Mint not shutting down Posted: 25 Jun 2021 08:14 AM PDT people! I use Linux Mint 19.3 Tricia and it's not shutting down sometimes. I have been researching and looks like a kernel panic with a BAD RIP value code,but I'm not sure and I don't know how to solve it. Sorry for the lack of information, but I don't know too much about Linux, but if some more information were necessary I can provide it. It's happening almost everyday I'm attaching the image of a screen that appear when it's not turning off and I press ESC:  Thanks for help!  |
| What is my hard drive physical sector size? fdisk, smartctl etc.. give different answers Posted: 25 Jun 2021 08:22 AM PDT The harddrive is connected with an external enclosure via USB3.0. $ sudo smartctl -a /dev/sdb === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 3.5 Device Model: ST4000DM004-2CV104 Firmware Version: 0001 User Capacity: 4,000,787,030,016 bytes [4.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5425 rpm Form Factor: 3.5 inches Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-3 T13/2161-D revision 5 SATA Version is: SATA 3.1, 6.0 Gb/s (current: 6.0 Gb/s) SMART support is: Available - device has SMART capability.

$ sudo blockdev --getbsz /dev/sdb 512
So what is the real hard drive physical sector size? I think it should be 4096, but I don't know why all other commands give me wrong result. - Btw, the reason why I want to find the real physical sector size is because I want to use
-b 4096 when running badblocks. Thanks a lot. - PS: If the answer is
4096, are there any other tools in Linux can show the real result other than smartctl? I found another command will show 4096: $ sudo hdparm -I /dev/sdb | grep -i physical Physical Sector size: 4096 bytes

| How to check if Linux booted on CSM/Legacy/BIOS mode in a PC with UEFI? Posted: 25 Jun 2021 09:21 AM PDT I'm doing an ssh to a PC that no one can actually physically reach, yet. Said PC was made after 2011, so it defintely has UEFI. The issue is that every posts on the web is about checking if the PC has a UEFI or BIOS (e.g. How to know if I'm booting using UEFI?), which is not what I'm trying to find out. My question is then pretty simple: How do I tell if a PC with UEFI, booted with CSM/Legacy/BIOS Mode enabled or not ?  |

| Schedule reboot in the background during debian preseeding Posted: 25 Jun 2021 09:27 AM PDT I want to schedule a 30-minute reboot timer inside a Debian preseed so that in case of download problems etc. the installation does not hang (requiring someone on-site to reboot the machine manually). I am installing from a netboot image. The following does not work (it does not run in the background, but in the foreground): d-i preseed/early_command string reboot -d 1800 &
d-i preseed/early_command string sh -c 'reboot -d 1800 &' ;
I think the culprit is the log-output program used here https://salsa.debian.org/installer-team/preseed/-/blob/master/preseed_command#L16 Is there an alternative way to accomplish the scheduled reboot? Bonus if I do not have to install additional software (again, network problems …)  |

| MDADM - Stop Resync and Force Clean - Possible and/or Safe? Posted: 25 Jun 2021 09:05 AM PDT I have been having issues with my FileServer recently. See "rcu_sched detected stalls on CPUs/tasks" - jiffies - ESXi Ubuntu 16 FileServer Guest I just rebuilt it since I couldn't get any guidance on the issue. Unfortunatley, its resyncing my array again. Seeing how this has been done multiple time in the last few days, I'm fairly confident that its "in sync". I have a few questions to that regard. - When it resync's what is happening, is it just doing read operations on every piece of data? I feel i'm really abusing my HDD's at the moment
- Can I cancel resync? (I still want to be able to use the MDADM Though!)
- So Can I force it to "clean" state and remount?
- Is resync automatic when you mount a new MDADM (This is a new VM), or is there an error in the metadata that is forcing a resync and I NEED to let it finish. (It takes about 24 Hours and my server is extremely slow during that time)
Thanks! Update: There are 4x 5tb HDDs in raid5 passed through via mapped raw lun to a VM guest which then exports nfs and smb. This question is mostly about if the commands i want exist for mdadm and what sync does.  |
| Fixing a problem with lightdm; boot-loop Posted: 25 Jun 2021 08:06 AM PDT I think I messed up my Ubuntu 17.04 a little. In order to describe my problem I can only provide the symptoms + a suspicious log-file. My quenstion on this is: 1.: Can I repair it by doing something with lightdm? (cf. below)? Symptoms: When I start the pc, it never reaches the log-in-mask. Instead it seems to be trying to launch the graphical surface over and over again, but always fails to do so. I can hardly work on it in this state. I can switch to Ctrl+Alt+F2 and log in via terminal. Here I can do stuff, but roughly all 30seconds the monitor becomes black and shortly displays 'No signal'. After some seconds I can re-switch to there and start from were I left. Reboot does not help. DISPLAY-variable is 1. $startx does not work. System: Ubuntu 17.04, build pc, all parts were bought 2 months ago. What I did: I installed pekwm and started it a few times, I also switched between the window-managers via $pekwm --replace& resp. $compiz --replace&. It worked fine. I installed conky and wrote a .desktop-file to autostart it. This never worked. I deleted said .desktop-file, after the problem occurred. Right before the problem occured, I do not recall having done anything else than firefox, LaTeX and mathematica. It MIGHT be, that I messed up lighdm, without realizing.

| How to automatically detect and write to usb with variable spaces in its name Posted: 25 Jun 2021 11:04 AM PDT I am doing the second BASH exercise from TLDP Bash-Scripting Guide, and I have most of it figured out up until the part when it comes time to copy the compressed files to an inserted USB. Home Directory Listing Perform a recursive directory listing on the user's home directory and save the information to a file. Compress the file, have the script prompt the user to insert a USB flash drive, then press ENTER. Finally, save the file to the flash drive after making certain the flash drive has properly mounted by parsing the output of df. Note that the flash drive must be unmounted before it is removed. As I progress with the script it is becoming less ..elegant, and was wondering if there was a better way to do this. I know creating files is likely not the most efficient way to do the comparisons, but have not got the shell expansions figured yet, and intend to change those once I get it working. The problem specifically is, to ensure that the usb is mounted and that I am writing to the USB and nowhere else. I am comparing the last line of df after the USB is plugged in with the last line of df from the diff between df before USB is plugged in and df after USB is plugged in, and looping until they match. Unfortunately, the diff result starts with a >, but I intend to use sed to get rid of that. The real problem is the path to where my usb is mounted is: /media/flerb/"Title of USB with spaces" To make this portable for USBs that may have different names is my best bet from here to do something with awk and field separators? And as a follow-up, I know this is pretty inelegant, and wonder if there is a cleaner way to go about this...especially because this is the second exercise and still in EASY. The output from the df tails is: /dev/sdb1 15611904 8120352 7491552 53% /media/flerb/CENTOS 7 X8 > /dev/sdb1 15611904 8120352 7491552 53% /media/flerb/CENTOS 7 X8
The script so far 1 #!/bin/bash 2 3 if [ "$UID" -eq 0 ] ; then 4 echo "Don't run this as root" 5 exit 1 6 fi 7 8 #Create a backup file with the date as title in a backup directory 9 BACKUP_DIR="$HOME/backup" 10 DATE_OF_COPY=$(date --rfc-3339=date) 11 BACKUP_FILE="$BACKUP_DIR/$DATE_OF_COPY" 12 13 [ -d "$BACKUP_DIR" ] || mkdir -m 700 "$BACKUP_DIR" 14 15 #find all files recursively in $HOME directory 16 find -P $HOME >> "$BACKUP_FILE" 17 18 #use lzma to compress 19 xz -zk --format=auto --check=sha256 --threads=0 "$BACKUP_FILE" 20 21 #making files to use in operations 22 BEFORE="$BACKUP_DIR"/before_usb.txt 23 AFTER="$BACKUP_DIR"/after_usb.txt 24 DIFFERENCE="$BACKUP_DIR"/difference.txt 25 26 df > "$BEFORE" 27 read -p 'Enter USB and press any button' ok 28 sleep 2 29 df > "$AFTER" 30 diff "$BEFORE" "$AFTER" > "$DIFFERENCE" 31 sleep 2 32 echo 33 34 TAIL_AFTER=$(tail -n 1 "$AFTER") 35 TAIL_DIFF=$(tail -n 1 "$DIFFERENCE") 36 37 until [ "$TAIL_AFTER" == "$TAIL_DIFF" ] ; 38 do 39 echo "Not yet" 40 df > "$AFTER" 41 TAIL_AFTER=$(tail -n 1 "$AFTER") 42 diff "$BEFORE" "$AFTER" > "$DIFFERENCE" 43 TAIL_DIFF=$(tail -n 1 "$DIFFERENCE") 44 echo "$TAIL_AFTER" 45 echo "$TAIL_DIFF" 46 sleep 1 47 48 done 49 exit $?

| Test if postfix is running Posted: 25 Jun 2021 11:24 AM PDT I'm searching for a reliable way to test if postfix is running from inside a bash script. My first attempt was simply trying pidof postfix, which doesn't work. Then I tried to get the postfix status: POSTFIX_LOCATION=/var/packages/MailServer/target/sbin/postfix # location of postfix result=`$POSTFIX_LOCATION status` if [ -z $result ]; then echo "Error: No status output from postfix" elif [[ "$result" == *"is running"* ]]; then echo "postfix is running!" else echo "postfix is not running!" fi
But even though the status is reported to the console, the result variable stays empty. This is the console output: postfix/postfix-script: the Postfix mail system is running: PID: 11996 Error: No status output from postfix
I finally found a way to test if postfix is running by getting the process name of PID: 11996, which is "master". So the following does work: pidof master
But this is not very verbose and I'm not sure if this is a reliable way to test if postfix is running. So my questions are: - How can I get the output of
postfix status from inside a bash script? - Anything I'm doing wrong there? - Is there a better reliable way to test if
postfix is running from inside a bash script?  |
| How do I scan grayscale with simple-scan? Posted: 25 Jun 2021 10:07 AM PDT I really like simple-scan because: - It's really simple
- It has an interface that fits with GNOME setup on Debian (unlike Skanlite)
However, I can't seem to be able to set it to scan in grayscale. How can I do this? The two options, photo and text seem to serve as colour and B&W respectively, which is a problem when I want to scan documents with a high level of detail but without colour (I scan a lot of documents and storage becomes an issue). Anyway, I realise that the ideal solution would be to use a proper scanning tool, but since I'm really just after exactly what simple-scan offers with one tiny extra feature I thought I'd ask in case someone knew how to set this up (maybe I can add a "grayscale" profile to the list?)  |
| Easy way to paste command line output to paste bin services? Posted: 25 Jun 2021 10:18 AM PDT Are there any command line tools on Linux that allow you to post output from commands or text files directly to a sharing service such as pastebin.com?  |
| Can emacs use gpg-agent in a terminal at all? Posted: 25 Jun 2021 07:54 AM PDT I understand that there are problems with getting pinentry-curses to work with emacs (see some of the comments on http://emacswiki.org/emacs/EasyPG), and so using emacs in a terminal isn't compatible with gpg-agent because of this. I can't use a graphical pinentry tool in this case as this is over an ssh connection to a remote machine. However, is it possible to feed the gpg-agent the passphrase beforehand and then have emacs use this, but not to prompt for a passphrase if the agent doesn't already have this info? What settings would allow this to work with notmuch.el and EasyPG? Or, are there alternative methods of caching the passphrase which would achieve the same effect, but may have security problems (which is the reason gpg-agent exists in the first place)?  |
