Yeah, either cd into the directory first, or pass it to find. But it’s like tar: I can never remember in which order I need to feed stuff to find. One relevant addition could be -xdev, to have find halt at file system boundaries. So: find /path/to/dir -xdev -type f -! -type l … > root@fireball /home/dale/Desktop/Crypt # `find -type f -print0 | xargs > -0 stat -c '%s %n' | sort -n | head -n 20` > -bash: 2: command not found > root@fireball /home/dale/Desktop/Crypt # I used the `` in the mail text as a kind of hint: “everything between is a command”. So when you paste that into the terminal, it is executed, and the result of it is substituted. Meaning: the command’s output is taken as the new input and executed. And since the first word of the output was “2”, you get that error message.

The script creates a new text file, with the current date and the dircetory in its name, and compresses it at the end. This allows me to diff those files in vim and see what changed over time. It also updates a symlink to the current version for quick access via bash alias. -- Grüße | Greetings | Qapla’ Please do not share anything from, with or about me on any social network. ...llaw eht no rorrim ,rorriM
