All background Bash scripts should start with this preamble:
set -euo pipefail exec > ~/log.log 2>&1
There are countless articles explaining why, and the main purpose of this one is a reminder for myself, so I won't go into the details. For reference:
- -e halts the script on error
- -u errors when using an undefined variable
- -o pipefail makes pipe error return value sane
- exec > ~/log.log 2>&1 redirect all output to ~/log.log
