I have a tiny script to prune empty directories from a structure. The
essential line is as follows:
tree --noreport -dfi "${1}" | tac | sed 's/"/\\"/g;s/^/rmdir
- --ignore-fail-on-non-empty "/;s/$/"/'|bash
Running it recently produced :
bash: command substitution: line 2201: syntax error near unexpected
token `('
bash: command substitution: line 2201: `rmdir --ignore-fail-on-non-empty
"/snapshot/Music/Etta James/The Essential Etta James/The Essential Etta
James (Disc 2)"'
I'm trying to understand why command substitution is happening at all,
since the opening paren isn't preceded by a dollar sign.
