Go to tmp :

cd /tmp; mkdir retmp; cd retmp

Create 10 files :

for i in {1..10}; do touch test$i; done

Remove all files except test10 :

rm !(test10)

find . -type f ! -name "*.foo" -name "*.bar" -delete

This command is recursive and will delete in all directories in ".". It will find and delete all files not specified with ! -name "pattern". In this case it's file extensions. -type f means it will only find files and not directories. Finally the -delete flag ask find to delete what it matches. You can test the command by running it first without delete and it will list the files it will delete when you run it.

Know a better way?

If you can do better, submit your command here.

What others think

Thx! Usual I done it with

find . ! -name ...

Nice tip.

Comment by bogomips 209 weeks and 2 days ago

Humph? It does not work in Z-Shell neither in BASH. Am I doing something wrong?

Comment by Minoru 209 weeks and 2 days ago

Got it working in BASH. It's all about 'extglob' option???set it:

shopt -s extglob

and command would work.

Still looking for solution for ZSH.

Comment by Minoru 209 weeks and 2 days ago

For zsh rm -f ^survivior.txt will do but it requires extended_glob

Comment by RanyAlbeg 209 weeks and 1 day ago

Thanks, RanyAlbeg. That really works!

Comment by Minoru 209 weeks and 1 day ago

You welcome ;)

Comment by RanyAlbeg 209 weeks and 1 day ago

I never feel comfortable specifying the file I want to keep in an rm command.

Comment by matthewdavis 209 weeks ago

Use backups a few times and then you'll get used to it.

Comment by RanyAlbeg 193 weeks and 6 days ago

As has been noted zsh uses "^" as the 'not' and while the use of 'not' for a none interactive rm may be potencially dangerious, the 'not' is not :)

Some examples:

ls *^.jpg

ls *[^$(date +%F)].*
