How can I delete contents in a folder using a bash script?

Question

I would like to clear out my /bin folder in my project directory. How can I do this?

I tried rm -rf ~/bin but no luck

Answer 1

~ is a shorthand to a current user home directory. So unless it's also your project directory you are doing something wrong. Other than that, clearing a directory would be

rm -rf ~/bin/*

And if you also want to clear the hidden files

rm -rf ~/bin/* ~/bin/.[a-zA-Z0-9]*

Make sure you are not doing

rm -rf ~/bin/.*

especially as root as it will try to clear out your entire system.

UPD

Why? Since wildcard (*) is interpreted by shell as zero or more characters of any kind the .* will also match . (current directory) and .. (parent directory), which will result in going all the way up and then down, trying to remove each file in your filesystem tree.
