I’m not sure why this was so hard to find, but now it’s working… I was initially working on having “find” -exec UnRAR but it didn’t seem to work too well (I couldn’t find a good one-liner to separate file directory and full-filename to put into the find -exec command, if you have one, let me know).
#!/bin/bash
find $PWD -type f -name '*.rar' -print0 |
while IFS= read -r -d '' file; do
dir=$(dirname "$file")
unrar e -o+ "$file" "$dir"/
done(some parts of the script was inspired from other online sources)
