Redirect debug output of bash script to file
- 01 Aug 2017: Post was created (diff)
I needed a way to debug my thunar (file manager) custom actions, as it doesn’t have a way of debugging these scripts itself.
I make my thunar Custom actions run a script that contains the following snippet at the top:
#!/bin/bash
logfile=~/tmp/bash-$$.log
exec > $logfile 2>&1
set -x
Where all debug output of set -x will go into $logfile. Great for making sure the supplied command arguments are sent from thunar as expected, which is why most of my custom actions didn’t work before.
