Remove all files except some from a directory

Question

When using sudo rm -r, how can I delete all files, with the exception of the following:

textfile.txt
backup.tar.gz
script.php
database.sql
info.         


        

Answer 1

I prefer to use sub query list:

rm -r `ls | grep -v "textfile.txt\|backup.tar.gz\|script.php\|database.sql\|info.txt"`

-v, --invert-match select non-matching lines
