A script for renaming movie files
Most of the time, when you get a movie file it's a directory containing the video file, maybe some subtitles, and a bunch of other junk files. The names of the files are usually crowded and unreadable. I used to rename them all myself, but I got tired of it, so I learned how to write shell scripts.
[stripper.sh](http://stripper.sh) is really useful tool, and it has saved me a huge amount of work over the last few years. It is designed to operate on a directory containing one or many subdirectories, each one containing a different movie. It formats the names of the subdirectories and the files in them and deletes extra junk files. This script is dependent on "rename," which is really worth getting, it's another huge time saver.
It has four options which can be used individually or together:
1. Option p: Convert periods and underscores to spaces
2. Option t: Trim directory names after title and year
3. Option s: Search and remove a pattern/string from directory and file names
4. Option m: Match file names to the names of their parent directories
5. No option or any other letter entered: Shows the user guide.
Here is an example working directory before running stripper.sh:
Cold.Blue.Steel.1988.1080p.s3cr3t.0ri0le.6xV_HAYT_

It's not perfect, there are some limitations, mainly if there are sub-subdirectories. Sometimes there are, with subtitle files or screenshots. The script does not handle those, but it does not delete them either.

Reading when user enters a response without hitting enter
I have this:

read response

This requires the user to press x [Enter], though.
How do I get it to listen and respond immediately after they press x?

How to Display Dynamic Menu Under Active Command Line Input in Bash Terminal?
I want to write a Bash script that implements a menu which updates in real-time directly beneath the active command line as the user types. Like what you see here with ble.sh , where the user was able to select "tmux" from options displayed below the line they were typing on.
I'm still a beginner, so I wanted to know if this is something feasible for me right now, or if it's more complicated than it appears. If it is feasible, how can I get started?

arguments with spaces to a script, run from another script
So here is an example with a simple script that just prints out its first, second and third argument.
Works as intended with both single and space-embedded arguments
~/tmp$ cat args.sh
#!/usr/bin/env bash
echo "1: $1"
echo "2: $2"
echo "3: $3"
~/tmp$ ./args.sh a b c
1: a
2: b
3: c
~/tmp$ ./args.sh a 'b b' c
1: a
2: b b
3: c
But now if i run this script from another script that uses a variable to pass the arguments, then the quotations dont work.
How can i get this working so that "b b" is understood as one single argument?
In reality these arguments are fetched from a text-file, but I tried to simplify as much as possible here.
~/tmp$ cat wrapper.sh
#!/usr/bin/env bash
args="a 'b b' c"
./args.sh $args
~/tmp$ ./wrapper.sh
1: a
2: 'b
3: b'

Using font colors in a HEREDOC
u/geirha made a comment in another thread about the proper way to use printf, and that sent me down a rabbit hole of learning the different printing styles. I don't do a lot of printing to the screen in bash (usually just error messages), but my 13 year old dog passed away recently so I'm distracting myself with unimportant projects.
As far as I can tell, the only way to use a HEREDOC is with cat. Which is fine, but when I try to change the font color it prints the literal text instead of changing the font:
cat << EOF
\0330;31m Whatever, dude \033[0m
EOF
# \033[0;31m Whatever, dude \033[0m
The only option I've found to change font colors is to create variables using either `echo -e` or `tput`:
# using tput
RED=$(tput setaf 1)
NORM=$(tput sgr0)
# or, using echo -e
RED=`echo -e "\033[0;31m"`
NORM=`echo -e "\033[0m"`
cat << EOF
${RED}Whatever, dude${NORM}
EOF
Are those really the only / best ways to do this?

Passing global variables into other scripts
Hi everyone, I am working on project, the project has multiple sh files.
main.sh has many global variables i want to share with later running scripts, first i think of use source main.sh, then i remeber that the variabes values will changed and i will import values before the change.
I know passing them as arguments is a valid option, but I don't prefer it, because the scripts i talk about could be written by user "to allow customization"
So to make it easier on user to write his script, by source vars.sh, and access all variables, I was thinking about functin like __print_my_global_variables "vars.sh"
Which will prints all global variables of the script into vars.sh
But i want to make the function generic and work in any script, and not hardcode my global variables in the function, so anyone have ideas?
Edit: I forgot to mention that make all global variables to environment variables, but I feel there is a better method than this

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=''

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.

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 scripts 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 script to combine all of these files together in one big bash file. which is my bashrc.
What about you guys?

The project hasn't been maintained for few months as I got busy on my 9to5 job. However, I’ve dedicated time for open-source contributions starting in 2025, and one of my current goals is to further develop writenow.
My next steps are to create a to-do list of future tasks and work on them in short-term iterations.

Trying to pass a regex via command line, and store it in a variable.
I, for the life of me, can't understand why I can't pass this regex as a variable and use it properly in my shell script. I have a text file that contains a number of strings that match a pattern, like this:
ECO "B40"
ECO "E61"
ECO "E63"
If I use grep, such as:
grep "\\"E[6-9\][0-9\]\\"" testdbs/testdb.pgn
It will correctly find all the ECO codes between E60 and E99.
However, If i try to pass "\\"E[6-9\][0-9\]\\"" to a script, it all fails.
For example, I'm passing it to the script as follows:
./script.sh --eco "\"E6-90-9\"" --input testdbs/testdb.pgn
And the script picks up the --eco flag via the typical getopts while loop:
case ${opt} in
h )
usage
;;
-)
case "${OPTARG}" in
eco)
ecoregex="${!OPTIND}"; OPTIND=$(( $OPTIND + 1 ))
;;
esac
esac
Later in my script, I try to use it like:
while IFS= read -r line; do
if [ "$line" =~ ^"$ecoregex" ]; then
ecomatches="true"
fi
done < $inputfile
But, it doesn't match. It either returns all the strings, or none of them. Any idea what I'm doing wrong?

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.

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.

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

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 Description 1
234234234 #Mod Description 2
345345345 #Mod Description 3
"
Basically, list each modID in a new line + adding a #comment?
Best regards, <3

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 scripting language and/or the nature of a shell scripting 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.

Pipe to background process
Hi!
I am trying to write a script 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
