dateutils' ordinal date format doesn't doesn't work; and everyone is still writing things in Python, so... ordinal dates in Shell
#!/bin/sh
today=$(date +'%A %e %B %Y') # obviously you can modify this line
D=$(echo $today | grep -E -o "(\b(|[0-3])[0-9]\b)")

Records from a camera, and takes audio from a soundcard connected in JACK. Edit variables to taste.
#! env /bin/bash
# ffpmeg-jack-AV-rec - record video from a webcam, audio from a soundcard, using FFMpeg in JACK.
# Corey Mwamba 2018
# You will need jack_autoconnect (https://github.com/kripton/jack_autoconnect)
# And FFMpeg. And JACK.
# the -thread_queue_size option for ffmpeg reduces xruns

Bash, inotify, FFMpeg script to convert audio files to a desired format by placing it in a folder. The example below is for Ogg Vorbis; change it to whatever you want. Then set the script to autostart (in DE or WM).
convert_ogg() {
ffmpeg -hide_banner -nostats -loglevel panic -i ~/audio/convert_to_ogg/$file -vn -b:a 320k ~/audio/convert_to_ogg/${file%.*}.flac &
echo "converting $file"
}
while true; do
inotifywait -m ~/audio/convert_to_ogg -e create -e moved_to | while read path action file; do
if [ ${file##*.} != "ogg" ]; then
convert_ogg

In 2014, I saw a page on Ice SSB (https://peppermintos.com/guide/ice/) which uses the user's browser to create a site-specific browser - I guess what some Android apps do to an extent, or Web Widgets. I then wondered whether it would be possible to do the same but WITHOUT installing a larger browser. Someone else would have done this in Python.

A quick script to record audio notes. I have this little thing bound to a keypress in JWM (opens in a terminal). Needs ffmpeg.
#!/bin/bash
today=$(date +%s)
echo "press q to stop..."
ffmpeg -f alsa -i hw:0 -v 1 ~/audio-notes/$today.flac $@

coreymwamba / start-JACK-on-USB-insert
Last active September 18, 2016 06:16
This is a simple script that brings up a Yad interface when I plug in my USB audio card. The interface then activates JACK. JACK is then killed when I remove the card. You won't be able to do this for a normal user through Udev, since it is a root process. This script is run from the autostart section of my window manager (JWM).
#!/bin/bash
#you will need to modify the device names for JACK...
choose_params() {
qy=$(yad --form --item-separator="|" --field "Purpose:CB" "CD|Live|HD")
jackparams=$(echo $qy | awk -F '|' '{print $1}')
case $jackparams in

Batteries. Laptops. Indicators. The eternal struggle. Conky tells you the percentage of the battery; acpi gives you a long string and an estimated time. This script, if used in Conky, will give you both.
#!/bin/bash
eval $(acpi -b | sed "s/Battery 0: //g" |sed "s/,//g"| awk 'BEGIN {FS=" "}; {print "ch="$1, "percent="$2, "countdown="substr($3,0,5)}')
