Question

I am trying to delete all contents in specific folder but it doesn’t seem to effect subfolder but it should, because bash command does it from console.

system('rm -Rf some_dir/*');

Answer 1

There is no need in asterisk in this command. If you want to remove directory together with files, remove the slash as well. Leaving the slash will delete files, but preserve directory.
