I already wrote a post about this topic. But as I do at work, I work in an agile manner at home. So here is an update to the post Find Missing Files in a Backup. The script there has been designed to be copied from the clipboard into the terminal. This time, I present you a script, which you may copy to a file, make it executable and reuse it easily. Further on, it fixes some minor issues with the original version (e.g. handling files with spaces and backup folders which are named differently, than the original folder).
For the more general idea of this script, please have a look at the former blog post (see link above). So here it is:
#!/bin/bash
src=$1
tgt=$2
(cd ${src} && ls) | while read file; do
found=$(find $tgt -name "$file" | wc -l)
if [ $found -eq 0 ]; then
echo $file
fi
done
Copy this into a file e.g. named backup-check.sh and give it exec rights:
$ chmod ugo+x backup-check.sh
Afterwards you can use it like this:
$ ./backup-check.sh original/ backup/
Exciting 🤓.
