I need to delete all files, except one (its name is defined), from a given directory.

How can I do this from the terminal in OS X? Can I do this with one single command?

shopt -s extglob && rm !(non_delete_file)

or

rm -f !(non_delete_file)

or

find . ! -name non_delete_file -delete

Note that the above find command will work recursively -- it will delete all files and directories in the current directory, and in all subdirectories. If that is a problem, use -type f (to match only files) and -maxdepth 1 (to match things only in the current directory, ignoring subdirectories)

find . -type f -maxdepth 1 ! -name non_delete_file -delete

  • +1, you arrived just a second before me with find command :) – DonCallisto May 30 '12 at 08:00
  • @DonCallisto, sorry, i don't know, next time i'll wait you :) –  May 30 '12 at 08:02
  • It's a good solution but how to avoid deleting system file like ./.DS_Store? Also with respect to the -name non_delete_file, in my case -name non_delete_file is a directory. I would it to spare it as well as the content inside. – Konrad Jan 19 '16 at 11:28
  • How to exclude more than one file or folder, can it work like rm -rf !(first) (!second) – Kristi Jorgji Jul 21 '23 at 15:16

  1. move the file that you want to preserve to somewhere outside the directory
  2. remove everything in the directory using your favourite method
  3. move the file that you want to preserve back into the directory

Not exactly 'hi-tech' but it is much harder to accidentally delete the file that you want to preserve if you use this approach.

Obviously, this approach fails if the file needs to continuously exist in the directory while all the carnage is happening.

Try

rm `ls | grep -v '^defined$'`
