alias sl=“ls“

None, I like to type

To save videos from certain streaming sites that are not supported by yt-dlp, I catch the M3U playlist used by the page and with that I use this script that gets ffmpeg to put together the pieces into a single file.

#!/bin/bash
if [ "$1" == "-h" ] || [ $# -lt 2 ]; then
	echo Download a video from a playlist into a single file
	echo usage: $(basename $0) PLAYLIST OUTPUT_VID
	exit
fi

nbparts=$(grep ^[^#] $1 | wc -l)

echo -e "\e[38;5;202m Downloading" $(( nbparts - 1 )) "parts \e[00m"
time ffmpeg -hide_banner -allowed_extensions ALL -protocol_whitelist file,http,https,tcp,tls,crypto -i $1 -codec copy $2

alias ed=$EDITOR

Extremely convenient on a qwerty keyboard.

This should probably be a default nowadays. Does even a single person here use the real ed ?

ganis :

git add -A && sudo nixos-rebuild switch --impure -j$(nproc)

Everyone who uses nixos probably has a similar alias set x)

Since 720p downloading isn’t really available on yt-dlp anymore, I made an alias for it

alias yt720p="yt-dlp -S vcodec:h264,fps,res:720,acodec:m4a"

i use

alias kimg='kitty +kitten icat' 

to display images in my terminal pretty simple but nice

I wrote this suite of scripts a few years ago and still use them to:

1. Boot into Ventoy and select a Debian Live environment
2. Optional: connect a storage device (local partition, USB drive, etc) for persistent storage
3. Modify cfg/cfg.sh if it’s the first time using the tool
4. Run setup.sh to configure the environment into a familiar/productive state

The tools are flexible on hardware (more directed toward x64 systems at this time), and I (almost) never have to worry about OS upgrades. Just boot into a newer live OS image once it’s ready. They are still a work-in-progress and still have a few customizations that I should abstract for more general use, but it’s FOSS in case anyone has merge requests, issues, suggestions, etc.

I wrote a script called please. You input please followed by any other command (e.g. please git clone, please wget blahblah) and a robotic voice will say “affirmative,” then the command will run, and when it completes, the robotic voice reads out the exit code (e.g. “completed successfully” or “failed with status 1” etc.)

This is useful for when you have a command that takes a long time and you want to be alerted when it’s finished. And it’s a gentleman.

I alias traditional stuff to better, usually drop-in versions of that thing on computers that have the better thing. I often forget which systems have the better thing, so this helps me get the better experience if I was able to install it at some point. For example I alias cat to bat, or top to htop, or dig to drill, etc.

alias fuck='sudo $(history -p \!\!)'

This tmux wrapper is remarkably convenient:

Usage:

# Usage: t [session-name]
#
# With no arguments:
#   Lists existing tmux sessions, or prints "[No sessions]" if none exist.
#
# With a session name:
#   Attempts to attach to the named tmux session.
#   If the session does not exist, creates a new session with that name.
#
# Examples:
#   t            # Lists all tmux sessions
#   t dev        # Attaches to "dev" session or creates it if it doesn't exist

function t {
	if [[ -z $1 ]]; then
		tmux ls 2> /dev/null || echo "[No sessions]"
	else
		tmux attach -t $@ 2> /dev/null
		if [[ $? -ne 0 ]]; then
			tmux new -s $@
		fi
	fi
}

jmpd(jump directory): fuzzy finds and opens directory with fzf

# fish shell
function jmpd
    set _selection $(fzf --walker=dir);
    if test -n "$_selection"
        cd "$_selection";
    end
end

I have a collection of about 8 machines around the house (a lot of Raspberry Pi) that I ssh around to from various points.

I have setup scripts named: ssp1 ssp2 ssba ss2p etc. to ssh into the various machines, and of course shared public ssh keys among them to skip the password prompt. So, yes, once you are “in” one machine in my network, if you know this, you are “in” all of them, but… it’s bloody convenient.
