Unfortunately zsh: how to delete contents in folder without deleting the folder? does not have any good answer.
I’m currently using rm -rf {.,}* and if that fails because there is no hidden file in the folder I do another rm -rf *. This is of course annoying, not least because I am prompted for confirmation twice (so just putting them in a row with ; wouldn’t solve much.)
Is there a solution that
- works in the presence and absence of hidden files;
- does not delete the current folder, even temporarily;
- prompts only once?
It must work in the current folder. If it also works for a specified folder, that’s nice to have but not a must.
>Solution :
zsh has the GLOB_DOTS setting to make * match hidden files; you can enable this globally with setopt glob_dots if you want, or for a pattern with the (D) glob qualifier.
% print dir/*(D)
So to remove all files (hidden and unhidden) you can use:
% setopt glob_dots
% rm -rf dir/*
# Disable glob_dots for just this pattern:
% rm -rf dir/*(^D)
Or:
% rm -rf dir/*(D)
Unless I missed something, I believe this should do what you want.
For more information see man zshexpn (which is comprehensive, but also quite dense and not an easy read; section 5.9 of the Zsh User Guide is a more gentle introduction, and I recommend spending some time reading through all of the User Guide because there’s lots of useful things in there).
