Wrapper around notify-send to display desktop notifications when long-running tasks complete.

tellme

#!/bin/bash

## tellme
# tellme displays a basic desktop notification using notify-send to be used when a long
# running task completes. It supports one optional argument, -l, which will show a "loud"
# notification. This depends on notify-send provided by libnotify.
# This script can be run to simply alert or to show the output of the commands:
# $ sleep 10 && tellme
# $ echo "I show on the notification" | tellme

notify () {
  if [ -z "$STD_IN" ]; then
    title=" "
    message="Your command has finished!"
  else
    title="Your command has finished with output:";
    message="$(echo -e \"$STD_IN\" | head -n 10)"
  fi

  # Loud will force you to click the notification away, and show bold text.
  if [ "${is_loud}" ]; then
    notify-send -t 99999999 "$title" "<span color='#DD2222' font='26px'><b>$message</b></span>";
  else
    notify-send -t 5000 "$title" "<span font='16px'>$message</span>";
  fi
}

# Checks if stdin contains anything. This is to use tellme as ... && tellme or ... | tellme
if [ -t 0 ]; then
  :
else
  STD_IN="$(</dev/stdin)"
  echo -e "$STD_IN"
fi

# Takes one optional command line param: -l for loud which makes the notification need to be clicked away
while getopts "l" o; do
  case "${o}" in
    l)
      is_loud=1
      ;;
  esac
done
