Variable populated by docker command acts odd

I would just like to understand why this occurs.

I am running a command on docker containers to get their network id:

iflink=$(docker exec -it "$container" bash -c 'cat /sys/class/net/eth0/iflink')

If I print out the var iflink, it is indeed populated, but it appears that if you try to print anything AFTER the variable, it strips characters after, and the order is weird.

As an example:

iflink=$(docker exec -it "$container" bash -c 'cat /sys/class/net/eth0/iflink')
echo "BEFORE........-${iflink}-...........AFTER"

You get this result:

# Expected
BEFORE........-1874-...........AFTER
BEFORE........-131876-...........AFTER

# Results
-...........AFTER1874
-...........AFTER^X131876

The way I found to solve this was to strip whatever is non-numerical

iflink=$(echo $iflink | sed 's/[^0-9]*//g' )

It works, but I'd still like to know what the heck is going on with the output. It should just be a numerical value

Bash not substituting variables on TAB, Macos; does on Debian

Hi!

I'm running Bash 5.2.37 on both my Debian box and my work's laptop, a Mac.

If I try to expand a variable value using Tab when using commands such as ls, Macos doesn't let me but Debian does. Whenever I try to expand a Bash variable by pressing Tab in ls $HO, I get a bell on Macos but I can do it on Debian; the expected behaviour is that I either get the expansion of $HOME (literally, with the $), or a list of suggestion with all of the variables that begin with that string. I have observed that this happens also with cp and mv, but not with user-defined functions or Macos commands such as open.

There are no completion files for the above commands in any of the computers.

Running shopt | awk '$2 == on {print $1}' on both machines returns the same activated options:

autocd
checkwinsize
cmdhist
complete_fullquote
direxpand
expand_aliases
extglob
extquote
force_fignore
globasciiranges
globskipdots
interactive_comments
patsub_replacement
progcomp
promptvars
sourcepath

(Not exactly true; the login_shell option is enabled on Macos for virtual terminals)

How can I solve this? My main reason of exporting variables is to autocomplete them when needed.

Thanks!

Named coprocesses, additional ones aren't enumerating their file denoscriptors.

So, I have my docker container in which I want to run my native binaries. Let's say I have

declare -r PROJECT='widget'
declare -ra MOCKS=(gadget what-sit) # thing-ama-jig)

in a file called project.sh, and when another noscriptlet called session.sh where I source that in, and then I loop over MOCKS to launch all of the programs:

for mock in ${MOCK@}; do
echo "Executing coprocess '${PROJECT}-${mock}/cmake-build-mock/${PROJECT}-${mock}.elf ${@}' as ${mock//[:punct:]/}"
coproc "${mock//[[:punct:]]/}" { ${PROJECT}-${mock}/cmake-build-mock/${PROJECT}-${mock}.elf "${@}"; }
# Plug co-process "${mock//[:punct:]/}" into the command-line interface.
done

And for the first mock program, `gadget`, it's working great. All of my mock programs are sitting out there, pretty as you please, I just need to get them all executing as named coprocs and then I can work on stitching together all of the file denoscriptors into something that makes sense.

$ . session.sh can0
Executing coprocess 'widget-gadget/cmake-build-mock/widget-gadget.elf can0' as gadget
Executing coprocess 'widget-what-sit/cmake-build-mock/widget-what-sit.elf can0' as whatsit
bash: warning: executecoproc: coproc [4:gadget] still exists
session.sh: line 14: widget-gadget/cmake-build-mock/widget-gadget.elf: cannot execute: required file not found

Well, it was working for the first mock program. Now, it's not. I was able to confirm the coprocesses were running with:

$ ps aux
...
root 6 99.5 0.0 3376 1720 pts/0 R 20:59 6:37 widget-gadget/cmake-build-mock/widget-gadget.elf can0
root 8 99.5 0.0 3376 1720 pts/0 R 20:59 6:37 widget-what-sit/cmake-build-mock/widget-what-sit.elf can0

I was also able to see the gadget file desciptors with:

declare -p gadget
declare -ar gadget=([0]="61" [1]="56)

So, the `gadget` coproc's `stdin` is hiding behind filedenoscriptor 56 and it's `stdout` is hiding behind file denoscriptor 61. I was able to confirm that by sending the `exit` command to the `gadget`'s `stdin` with:

echo exit >${gadget[1]}

and the `widget-gadget.elf` process noped out, as it should.

But then, I couldn't do the same thing with the `widget-what-sit.elf` process. Because some of my mock program names have punctuation in them that aren't conducive to shell symbol names. That's why I use the syntax `"${mock//[[:punct:]]/}", so all of the punctuation marks will become underscores, which are valid symbol name characters. That makes the widget-what-sit.elf's coprocess name into whatsit`. But if I try to list what-sit's file denoscriptors:

$ declare -p whatsit
bash: declare: whatsit: not found

It's not there. And I'm eventually going to add the thing-ama-jig mock program to the bouquet as well, so I need to be able to access those file denoscriptors for all of my mock processes.

The warning:

bash: warning: executecoproc: coproc 4:gadget still exists

is apparently from when it launches the widget-what-sit.elf coprocess and the gadget coprocess still exists at that moment, and so I guess it's not creating the what_sit file denoscriptor array. But, it's supposed to!

What's going wrong? What am I missing?

Apologies for the formatting ahead of time. I dont usually post, if someone could tell me what shortcut to use to format it properly would be appreciated.

Code is garbage, I’m sure, but i am not an expert by any means - Essentally what i am trying to accomplish, is to pull down files from a remote server via sftp. Running this noscript, it does it, but for some reason , when i try to add logic for the notifications, via email to update up when there are no changes, email subject should read - no changes - but whenever i add a file, it shows it and still runs a. The batch job process and pulls the file, but it keeps spitting out “changes” no matter if there is a change..e.x a file added…I can’t

tell if its my shitty code or something which is an underlying issue - open to feedback :)

A process I'm trying to pipe data into using a named pipe reports a "Read error"

Hello everyone!! So I've been trying for the last hour and a half to get the "fftest" process to receive the input "0", so it would run its part of the program. It used to work, but after a couple of attempts and deleting the named pipe file it just stopped working.

The problematic code is this:

#!/bin/bash

loop(){
while [ 1 ]
do
sleep 2
echo 0 > pipef
sleep 18
done
}

mkfifo pipef
cat > pipef &
mypid=$!

trap "pkill -f fftest" SIGINT

loop &
looppid=$!
fftest /dev/input/by-id/usb-MediaTekInc.XBOXACC000000000-event-joystick < pipef

kill $mypid
kill $looppid
rm pipef

I'm creating the loop function that's responsible for the data input, then I open the pipe, then I run the loop, so it would pipe its data when the time comes and then I run the "fftest" command itself. The moment that command is ran it exits, reporting a "Read error".

This code used to work before, until it randomly stopped (that's why I created the new one in an attempt to fix it):

#!/bin/bash

mkfifo pipef
cat > pipef &
mypid=$!

fftest /dev/input/by-id/usb-MediaTekInc.XBOXACC000000000-event-joystick < pipef &
sleep 2
while [ 1 ]
do
echo 0 > pipef
sleep 20
done

kill $mypid
rm pipef

If you have found my mistake, please tell me!! Thank you so so much in advance!!! <3

Edit: This is the output with set -x:

+ mkfifo pipef
+ mypid=31874
+ trap 'pkill -f fftest' SIGINT

I've created windows switcher

I created something handy today and I would like to share it and maybe get your opinion/suggestion. I've created window switcher noscripts that mapped to Ubuntu custom shortcut keys. When triggered it instantly finds the intended windows and switch to it no matter where you are in the workspace (reduces the need for constant alt+tab). This minimizes time and effort to navigate if you have many windows and workspace on. It uses wmctrl tool

I've created so far four switchers: terminal switcher, firefox switcher, google-chatgpt switcher, youtube switcher since these are my primary window cycles

wmctrl -a ubuntu <your_username>@ubuntu:~

//google\_sw.sh (it actually is a chatgpt switcher on google browser. The only way i know how to do chatgpt switcher)

I've been taking an introduction to Linux and Bash course at my college and we came across this case when using echo and command substitution with variables. I thought that it would actually print the random number, but no matter how many echo $() I put, it always prints $RANDOM

export META='$RANDOM'

echo $(echo $(echo $META))

Tar2Deb

Pure bash noscript that converts a tar file into a deb file

in order to install tar2deb you need wget, note only works for debian based distros.

features

automatically move images in the extracted tar directory that holds a subdirectory with the most images then export it as a variable then moves to the deb directory, the deb directory is needed in order to create a .deb file, it uses imagemagick to move each image by dimension, before the dimensions and after is extracts the tar file it will ask the user what does want the package name be, does not allow numbers except 2, then the name of the package the user chooses will be exported as a variable, then it will ask the user what is version of your package, once the user chosen its version for the package it will be exported as a variable then combine those to variables like this $PackageName-$Version then it will create the directory with those 2 variables then it will ask the user what name of the maintainer, whatever name the user decides will be exported as a variable, then it asks the user what is the package about, whatever the users type will also because exported as variable, then it will create the control file in the deb dir DEBIAN folder, then once the control file is created, it will create the directories in the deb directory, then it will find a graphical executable file (excluding binary files) and move to deb_dir/usr/bin after it does then it will go the dimensions after it moves the dimension it will ask the user a yes or no prompt asking if it wants to rename all image files moved into one name if the users say no then it will ask the user if it wants to rename a file from the numerical list and whatever numbers it chooses it will prompt the user what the name to be for the file then it combine that name with the file extension and renames the chosen file with the name that user choose, then it create a desktop if there is not an desktop file in the tar directory it will ask the user if it wants to create a desktop since there is not located in tar directory if the users say user then it do a prompt asking the user what executable file it wants to choose for desktop file then it will show a numerical list showing a list of images and whatever image the user chooses will be the icon of the desktop file once the desktop file is

how to install tar2deb
