Remove files older than 30 days without using find, using a shell script

Question

I have been looking for quite a while for an answer to this.

My hosting environment will not let me use the find command. Is there a way to search a directory for all files older than 30 days and delete/rm them? Any reading or examples would be greatly appreciated.

Thanks in advance.

Answer 1

Try something like this:

touch -d 'now -30 days' reference_file
for f in *; do
    if [ "$f" -ot reference_file ]; then
        rm "$f"
    fi
done

Or is touch also on the blacklist?
