On a GNU system, you could do:
find /home/ -mtime +10 -type f -size +100M -delete -printf '%h\0' |
awk -v RS='\0' '!seen[$0]++ {out = out $0 RS}
END {printf "%s", out}' |
xargs -r0 rmdir
We use awk
to filter out duplicate while still keeping the order (leaves before the branch they're on) and also delay the printing until all the files have been removed so rmdir
can remove empty directories.
With zsh
:
files=(/home/**/*(D.LM+100m+10od))
rm -f $files
rmdir ${(u)files:h}
Note that those would remove the directories that become empty after files are removed from them, but not the parent of those directories if they don't have any of those files to delete and become empty as a result of the directories being removed. If you want to remove those as well, with GNU rmdir
, you can add the -p
/--parents
option to rmdir
.
If you wanted to remove all empty directories regardless of whether files or directories have been removed from them or not, still with GNU find
, you could do:
find /home/ \( -mtime +10 -type f -size +100M -o -type d -empty \) -delete
