  • here we go:

    dedup:

    #!/usr/bin/awk -f
    !x[$0]++
    

    this removes duplicate lines, preserving line order

    iter:

    #!/usr/bin/bash
    if [[ "${@}" =~ /$ ]]; then
        xargs -rd '\n' -I {} "${@}"{}
    else
        xargs -rd '\n' -I {} "${@}" {}
    fi
    

    This executes a command for each line. It can also be used to compare two directories, ie:

    du -sh * > sizes; ls | iter du -sh ../kittens/ > sizes2
    

    fadeout:

    #!/bin/bash
    # I use this to fade out layered brown noise that I play at a volume of 130%
    # This takes about 2 minutes to run, and the volume is at zero several seconds before it's done.
    # ################
    # DBUS_SESSION_BUS_ADDRESS is needed so that playerctl can find the dbus to use MPRIS so it can control mpv
    export DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus"
    # ################
    for i in {130..0}
    do
        volume=$(echo "scale=3;$i/100" | bc)
        sleep 2.3
        playerctl --player=mpv volume $volume
    done
    

    lbn:

    #!/bin/bash
    #lbn_pid=$(cat ~/.local/state/lbn.pid)
    if pgrep -fl layered_brown
    then
    	pkill -f layered_brown
    else
    	export DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus"
    	mpv -ao pulse ~/layered_brown_noise.mp3 >>lbn.log 2>&1 &
    	sleep 3
    	playerctl -p mpv volume 1.3 >>lbn.log 2>&1 &
    fi
    

    This plays “layered brown noise” by crysknife. It’s a great sleep aid.

    here are some aliases:

    alias m='mpc random off; mpc clear'
    alias mpcc='ncmpcpp'
    alias thesaurus='dict -d moby-thesaurus'
    alias wtf='dict -d vera'
    alias tvplayer='mpv -fs --geometry=768x1366+1366+0'

    This is not that big of a deal most of the time, since you are the only person interacting with your computer, but it’s worth remembering when you decide to recycle or donate – you have to securely wipe in that case. Also bear in mind, if you do encrypt your drive, there are now more possibilities for total data loss.

    Oh, fun fact: you can change a users windows password inside Linux. Comes in handy for recovery, ie, user forgot their password.
