Remove all but One
$ rm-but() { ls -Q | grep -v "$1" | xargs rm -r ; } Add this to your .bashrc file. Then whenever you need to remove all files/directories but one from present working directory. Run: $ rm-but Notes: 1. This doesn't affect the hidden files. 2. Argument is actually as string. And all files/directories having this string in there name are left untouched.
