Sample, if you have multiple files like
20221227 2210 - Random TV Chanel HD - Make Arch Great Again.ts
but you need only 'Make Arch Great Again.ts', use
for file in *.ts; do
echo mv "$file" "${file#*-*- }"
done
in '#!/bin/bash' script.
Remove 'echo' if the output looks ok.

Start and stop your conkys with a simple command
This script will start a conky if it's not running; if it is running, it will kill it.
Useful for keybindings; as the same keybinding will either start or stop the conky.
It takes the name of the conky config file as an argument.
Please note to use it, you must call your script "toggleconky.sh"; this is due to the grep declaring the PID variable: we only want the line output of ps that has the actual running conky.
PID=`ps -ef | grep -v -P 'grep|toggleconky' | grep -o -P $REGEX | awk '{print $2}'`
You can name your script anything, but change that line accordingly.
#!/bin/sh
# USAGE: toggleconky.sh <name of conky config>
CONFIG=""
if [ -z "$1" ]; then
exit 0
else
CONFIG=$1
fi
#echo $CONFIG
REGEX='.+conky.+'$CONFIG
#echo $REGEX
PID=`ps -ef | grep -v -P 'grep|toggleconky' | grep -o -P $REGEX | awk '{print $2}'`
#check if PID, if not, we start, otherwise, kill
#echo $PID
if [ -z "$PID" ]; then
#echo 'not found...start'
conky -c ~/.config/conky/$CONFIG
else
#echo 'found, kill'
kill -9 $PID
fiMany user use more than one conky files
I use
killall conky
done
And as sample
conky -c ~/.config/conky/conky-shct
or use an alias for that.
But basically I have conky because I want to see it
But basically your script is a nice thing. 
Agree, Conky is made to be seen. But this is Linux, and you do it because you can
Actually wrote the script for when I was developing lua conkys....I'd create the occaisional bug (not often, most of my code is bug free ) and lua would start dumping reams of stdout....it was easy to just use my toggleconky.sh to stop it and start it again...."!!" became my friend.
I have a section of my monitor now for "wildcard" conkys. I can choose which one I want there and use my keybindings to display it (or kill it).
The script actually morphed from a similar use case where I needed to start/stop a process from a keybinding (because its a headless computer governed by a flirc remote). The tricky part is getting all the grep/regex to extract the PID so you can execute kill.
Like the "killall" suggestion...when I was a wee lad, all I had was "kill".
A couple simple fish shell abbreviations for the lazy ones like me:
abbr -a .dots -r '\.{3,}.*' --position anywhere -f _abbr_dots
function _abbr_dots
string match -qr '\.\.(?<dots>\.+)(?<rest>.*)' -- $argv
echo ..(string replace -a '.' '/..' -- $dots)$rest
end
Allows to shorten repeated leading ../ with multiple dots also when entering a filename, e.g.
micro .../file.txt expands to micro ../../file.txt.
abbr -a .conf -r '~~.*' --position anywhere -f _abbr_conf
function _abbr_conf
test -n "$XDG_CONFIG"
and set -l cfg $XDG_CONFIG
or set -l cfg ~/.config
set -q _abbr_conf_tab # skip expanding the shortcuts on tab completion
or switch $argv # shortcuts for frequently used files and dirs
case '~~f' ; set argv '~~fish'
case '~~fc' ; set argv '~~fish/config.fish'
case '~~fcd' ; set argv '~~fish/conf.d'
case '~~ffn' ; set argv '~~fish/functions'
case '~~fa' ; set argv (status -f) # this file
case '~~s' ; set argv '~~sway'
case '~~ss' ; set argv '~~sway/scripts'
case '~~scd' ; set argv '~~sway/config.d'
case '~~w' ; set argv '~~waybar'
case '~~wc' ; set argv '~~waybar/config'
case '~~ws' ; set argv '~~waybar/scripts'
case '~~wss' ; set argv '~~waybar/style.css'
case '~~grub' ; set argv '/etc/default/grub' # shortcuts do not need to be in .config
end
set -e _abbr_conf_tab
string replace -r '^~~' $cfg/ -- $argv |string replace -r ^$HOME/ '~/'; or true
# reset status in case the path wasn't in $HOME and the second replace failed
end~~~
Allows to shorten ~/.config[/name] with ~~[name], where 'name' can also be one of the configured shortcuts (the case statement and _abbr_conf_tab can be removed if no shortcuts are desired).
Note that Ctrl-Space can be used to avoid expanding, and Ctrl-Z to undo the expansion after the fact.
File completion won't work until after expansion, which is somewhat annoying.
I see no downside in binding / and tab to also first expand abbreviations though:
bind / expand-abbr self-insert
bind \t expand-abbr complete # or (to skip shortcuts on tab completion):
bind \t 'set _abbr_conf_tab; commandline -f expand-abbr; commandline -f complete'
# NOTE: 'set _abbr_conf_tab' expand-abbr complete does not work
and, why not (unrelated):
bind \e 'commandline -P; and commandline -f cancel; or commandline -f kill-whole-line'
Note: bindings (especially \t) may be ignored depending where they are issued, e.g. in conf.d.

Copy command output or file(s) contents from command line, wrapped in forum markup ([details] and ~~~) with relevant details text. Most common escape codes are stripped by default.

sed -E "$esc_filter"
printf %s\n "~~~" "[/details]" ""
end
function _forum_copy
# this is to work around wl-copy detecting some text as binary data (embedded control chars?)

or .cf $argv
else

Use directly from command line, with redirection:
COMMAND | forum.fish
forum.fish <FILE
Use directly from command line, with arguments:
forum.fish FILE...
forum.fish -c COMMAND
forum.fish -i == -c garuda-inxi
Use the functions after sourcing it:
.cf FILE... copy the FILE(s) contents
.cc COMMAND LINE copy the output of COMMAND LINE
.inxi copy the output of garuda-inxi
Options:
-a --ansi allow ANSI escapes (default no)
-l --lang set syntax language (printed after ~~~, default "text" for command output)
-d --details set details text (default filename or command, can't be set for files given as arguments)
Limitations/problems:
When piping into the script, details text will be "pipe:[XXXX]" by default.
Cannot pipe/redirect into .cc and .cf functions, only the main script.
Some combination of arguments may be nonsensical.
Not all ANSI escape sequences are stripped.
(I'll probably fix these issues some day).
Other notes:
Does not depend on wl-copy anymore and should work on all environments (thanks to the fish_clipboard_copy function).
@sgs
To be able to run fish scripts from your terminal, you have to do two things.
#!/usr/bin/env fish.chmod +x <YOUR_FISH_SCRIPT_FILENAME>.Ah, I forgot to say, forum.fish is supposed to be sourced somewhere in the in the fish config.
It does not run as forum.fish from the command line.
Now that you mentioned it though... hold my beer.

I though wl-clipboard was installed by default, my bad.
I don't know why "failed to connect" though, it works here.
Whoogle time.
didn’t you say you use X11? Dare I request an inxi from the master of inxis?
Always depends on which computer I am using, better, which DE is running on it.

Note: since the icons are not all the same width I had to put a tab in there to keep the labels aligned.
It would cause excessive spacing between the icon and the label though, hence the padding.
It may need adjustment. First padding character has to be some other invisible than a normal space.
The final line expects the tab to be there, to split the icon away and then pass the remaining lowercase label text to grimshot.
If the items appear scattered around, it's likely too much padding (depends on the font size).
If the items appear shuffled, it's likely a wofi bug (I think it's worked around with -k /dev/null though).
Tried to get up and running with Davinci Resolve yesterday, and lets just say it wasn't a smooth experience 
. Turns out onetbb causes it to hang on launch, and one of the recommended fixes is to rename libOpenCL.so temporarily. Thus bringing about the birth of this script.
#!/bin/bash
# /usr/bin/start-resolve.sh
# hacky startup script for bugged davinci resolve on systems running onetbb
# renames libOpenCL.so to bypass davinci hang, then restores
user="kilo" # replace with the username you use resolve with
exec=/opt/resolve/bin/resolve "$@"
dir="/opt/intel/oneapi/compiler/2023.0.0/linux/lib"
file="libOpenCL.so"
delay=2
rename() {
from="$dir/$file"
to="$dir/_$file"
if [ $1 == 1 ]; then
if ! [ -f $from ]; then return 0; fi
echo "renaming $from"
mv $from $to
else
if ! [ -f $to ]; then return 0; fi
echo "restoring $from"
mv $to $from
fi
return 1
}
restore() {
sleep $delay
rename 0
}
launch() {
echo "running $exec as user $user"
sudo -u $user $exec ;
}
cleanup() { rename 0; }
trap cleanup EXIT
rename 1
restore & launch
Unfortunately it requires root to run mv in this location, so chmod +x the file. That means you'll need to type a password to run Resolve. A bit annoying, but not the end of the world.
I tried to slap this into a desktop file, and run in the background, but was unsuccessful. That means I've been running it with the terminal open. So, in it's current state, that's another slight annoyance. Oh well, beats manually renaming the file manually every time, I guess.

I'm new to bash, and always open to suggestions and criticisms. If anyone knows how to make this run in the background, I'd gladly update this post with the provided information. I tried Exec=sudo -i sh -c "/usr/bin/start-resolve %u &", and a couple other weird things, but it refuses to run.
Edit: Whoops, slight bug in the .sh causing the file not to be renamed back on delay, fixed.
Edit 2: One solution is to use Exec=sudo -i bash -c "nohup /usr/bin/start-resolve %u &" but I'm not sure if that's ideal since I read it'll persist through logout.
You can kick a terminal program to the background with Ctrl+Z to interrupt, then bg to resume in the background. I don't know how to incorporate that into the script, but at the very least you could type it in manually so you can close the terminal after the script is running.
Neat tip, thanks. I'll have to look more into this as it didn't seem to work while resolve is running.
Oh bummer, it's not running once you start it in the background with bg you mean?
This article says with a single ampersand you can start a script in the background to begin with.

I better get out of this thread, my scripting skills are pretty flimsy!
I’m not sure if it’s because I’m starting it up with sh -c or what. Trying to suspend works if I run from terminal directly, but just results in ^z being printed from the .desktop launch.
I tried with the &, but there must be something simple I’m missing as to why that doesn’t work. ¯\_(ツ)_/¯
LOL, yeah I’m in the same boat. Regardless, I appreciate the efforts.
Perhaps I should stick to web development
