-t 0 for testing terminal not working as expected

In window manager (Sway) I bind the following:

bindsym $mod+5 exec -t 0 && notify-send "run from terminal"

and it reports it runs from terminal even though it's running from a keybinding executing the command.

I'm also using this check and it's not working as expected when running the noscript from status bar calling the command to the noscript.

Why might this be the case? My attempt is to determine whether to run fzf (cli) or dmenu (gui-equivalent) depending on whether it's run from the terminal. Can this be done reliably?

Looking for a corpus of Bash noscripts

I'm looking for a large corpus of open source Bash noscripts; preferably longer noscripts, but that doesn't really matter.

At the moment, I've found:

The `tests` directory in the [Bash repository](https://savannah.gnu.org/git/?group=bash). This is quite large, but it contains a lot of funky stuff for teasing out edge cases:

$ find tests -name "*.tests" -o -name "*.sub" -exec wc -lc --total=only {} \+
19364 467878

[This repository](https://github.com/bensuperpc/noscripts), which was mentioned on this subreddit [about three years ago](https://old.reddit.com/r/bash/comments/ox3sry/collection_of_bash_noscripts/) and contains a lot of quite short, but more "normal" noscripts:

$ find . -name "*.sh" -exec wc -lc --total=only {} \+
12074 400232

The purpose of this is to stress-test formatting engines and to get an idea of throughput.

Noob to Bash—Having Trouble Restarting RMM Service via Script, Need Help"

Although I have a workaround, it's not ideal. The workaround is to force the computer to restart once the service stops, but it doesn't always work, and it’s not a reliable solution.

I’m running the bash noscript via an RMM tool where the noscript executes as root. The issue arises when using sudo through the terminal, as the noscript works fine there.

Here’s the command that works when run manually:

sudo launchctl bootout system /Library/LaunchDaemons/com.cenra.cag.plist
sudo launchctl bootstrap system /Library/LaunchDaemons/com.cenra.cag.plist


The challenging part is that the service I'm trying to restart is actually the RMM itself (yes, the RMM is broken, haha).

What I’ve tried so far is running a cron job and saving the noscript in the logged-in user's profile under /Library, then executing it. The noscript is able to bootout the service, but it fails to bootstrap it.

I’ve even attempted to pass temporary admin credentials through the noscript itself.

I know I might be overthinking this, as this is only my second bash noscript. Any help would be greatly appreciated!

Continuous deployment on LAN/local server upon 'git push' - using webhook & ngrok

Just finished a new bash noscript pforret/landeploy


It helps me setup a local webhook, make it public with ngrok and use it in Github/BitBucket to trigger a redeployment whenever I push a new version. I need this because we have a server at the office with a custom Windows software on it (that we can't run in the cloud), and I need the project to auto-update when we push changes to GitHub. The redeploy noscript runs under WSL.


It is a bash noscript based on the bashew micro framework.

and so does sleep

why does it say sleep missing operand?

Pipe to background process

Hi!

I am trying to write a noscript which opens a connection with psql to PostgreSQL, then issue commands and get their response, multiple times synchronously, then close the background process.

I have got stuck at the part to spawn a background process and keep its stdin and stdout somehow accessible.

I tried this:

psql -U user ... >&5 <&4 &
PID=$!

# BEGIN - I would like to issue multiple of these
echo "SELECT now()" >&4
cat <&5
# END

# close psql
kill -SIGTERM $PID

Apparently this is not working as fd 4 and fd 5 does not exist.

Should I use mkfifo? I would like to not create any files. Is there a way to open a file denoscriptor without a file, or some other way to approach the problem perhaps?

I am trying to execute this noscript on Mac, so no procfs.

How many lines is your bashrc file? Mine is currently 4712 and counting rapidly

I (like many others of you probably) have an addiction of trying to automate every single thing I do and creating bash noscripts for it. Every single tool i make, I put in my bashrc file. Over the course of just 4 months I have gathered 4712 lines of code

At some point it even got to the point where I had to split up the bashrc file in multiple files, and create some sort of framework to create 'composite' commands where i can have one main command and multiple sub-commands like 'profile load' 'profile save' 'profile list'. see example:

alias profile="profile_main_command"

# Composite command
profile_main_command() {
    reset_ifs

    composite_define_command "profile"
    composite_define_subcommand "list"
    composite_define_subcommand "current"
    composite_define_subcommand "load"
    composite_define_subcommand "save"
    composite_define_subcommand "edit"
    composite_define_subcommand "delete"

    composite_handle_subcommand $@
}

This will even automatically make a \`profile help\` command.

All of these tools and handy bash code, i have split up in several bash files, and then I use another bash noscript to combine all of these files together in one big bash file. which is my bashrc.

What about you guys?

Bash linting, formatting, etc. tools worth using?

I'm setting up Neovim and typically people set up tools like LSP servers, linting, formatting, etc. to aid in writing code.

Currently I use only use bashls and Neovim diagnostics that rely on shellcheck (still looking for a way for diagnostics to show the relevant code warnings like "SCXXXX" as virtual text so I don't have to manually search up the actual warning and potentially disable it).

Anyone use tools like beautysh, prettier, etc.? Are they as mature as similar tools in other languages? I would like to get a sense of perspective since I don't yet have experience with other "real" programming languages. E.g. maybe such tools aren't as useful for a shell noscripting language and/or the nature of a shell noscripting language is perhaps too opinionated that such tools don't help much.

Any recommendations for tools, however trivial, is much appreciated. I've never used an "industry-standard" code editor like VS Code or a real IDE, so don't know what I might be missing with a barebones Neovim setup.

Newbie question regarding #comment within an array of multiple values.

Hello, I have the following code below:

ModEnabled="1" # If 1 = Install/update mods
GameModList="123123123 234234234 345345345"

if $ModEnabled == "1" ;then
printf " ${yellow}REALM-SERVER${default} Updating/Downloading Mod files!\n"
for value in $GameModList; do
${HOME}/servers/steamcmd/steamcmd.sh \
+forceinstalldir ${HOME}/servers/gameserver/ \
+login "${SteamUser}" \
+workshopdownloaditem 123123 "${value}" \
validate +quit
done

printf " ${green}REALM-SERVER${default} Done downloading and updating Mod files!\n"
else
printf " ${red}Error${default} You have not enabled downloading and updating mods, skipping!\n"
fi

However,

GameModList="123123123 234234234 345345345"

Is going to be extremely big soon. My question is basically:

Is it possible do something like this:

GameModList="
123123123 #Mod Denoscription 1
234234234 #Mod Denoscription 2
345345345 #Mod Denoscription 3
"

Basically, list each modID in a new line + adding a #comment?


Best regards, <3

Is there a way to run an animation in the terminal while still typing commands without ending the animation?

Recently, I got interested in Neofetch (the terminal tool that shows system info in a cool way) and thought it would look so much better if the ASCII art was animated. I searched online but couldn’t find anything that lets you have animations while still using the terminal normally.

https://preview.redd.it/ovwg7912bwae1.png?width=1142&format=png&auto=webp&s=d22cc1e311da1166eb8c35fef426da5e4f7f8be3

I tried some ideas, like messing with the terminal buffer memory and using libraries like ncurses, but they either made the code super complicated to maintain or broke normal terminal usage.

So, my question is: is there any software that can do these two things?

1. Give high control over the terminal in a background process.
2. Let me use normal commands like cd or nvim without visual glitches.

If this is a dumb question and the solution is super obvious, feel free to call me out

how do you splitt(=divide in 2 parts) a pdf using qpdf?

Hi, I am trying to get 2 pdf's of 1 (the original.pdf) for add later some pages in the middle and then I will get 1 again ¿collating? and get the original more big.

I looked online help and found the command splitt but It does a partition of 2 pages groups of the entire pdf, it strepps the pdf.

i need only 1 partition in the pag 45 for example

I found this:

qpdf --split-pages=2 infile.pdf outfile.pdf: output files are outfile-01-02.pdf through outfile-11-12.pdf

from: https://qpdf.readthedocs.io/en/stable/cli.html#option-collate

I hope you understand my question.... and of course if you know later how to get 1 again entired tell me

sorry my not EN lang. here.

Thank you and regards!

Why is this cURL request printing results to the screen?

I'm working on an API for Cloudflare, and I have this (almost straight from the docs):

curl "https://api.cloudflare.com/client/v4/zones/$zone_id/dns_records?per_page=50000" \
-4 \
--silent \
--header "X-Auth-Email: $email" \
--header "X-Auth-Key: $key" \
| jq -r '.result[].id' \
| while read id
do
curl -4 --request DELETE \
--url "https://api.cloudflare.com/client/v4/zones/$zone_id/dns_records/$id" \
--silent \
--header "X-Auth-Email: $email" \
--header "X-Auth-Key: $key"
done

Here's the doc on it, very short and simple:

[https://developers.cloudflare.com/api/resources/dns/subresources/records/methods/delete/](https://developers.cloudflare.com/api/resources/dns/subresources/records/methods/delete/)

For some reason it's printing this to the screen for each item it deletes:

{"result":{"id":"foo"},"success":true,"errors":[],"messages":[]}

I know that I can just add `> /dev/null 2>&1` to the end of the second curl (inside the while loop) to stop it from printing, but why is it doing it in the first place? None of the other curl statements print to the screen like that.

Understanding indirect expansion ( ${!foo} )

I'm having a hard time getting my curl to return an error so that I can test this, so I'm hoping that someone can look at this and tell me if I'm using ${!foo} correctly?

I get the general concept that you use it when the value is used as the name of another variable, so is {!} always used when referencing an array with a variable key?

declare -A dns

# run several curl commands and set the return to a value of the array
dnsfoo=$(curl blahblahblah | jq '.errors | .message')
dnsbar=$(curl blahblahblah | jq '.errors | .message')
dnslorem=$(curl blahblahblah | jq '.errors | .message')
dnsipsum=$(curl blahblahblah | jq '.errors | .message')

# loop through dns and print any error responses
# do I need indirect expansion here?
for key in "${!dns@}";
do
if -n "${!dns[$key}" ]
then
printf "\0330;31m"
printf "DNS '$key' for $domain failed...\n"
printf "${!dns[$key}\n"
printf "\0330m\n"

# clear it so that it doesn't match later
dns[$key=''
fi
done
