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

You can use GLOBIGNORE environment variable in Bash.

Suppose you want to delete all files except php and sql, then you can do the following -

export GLOBIGNORE=*.php:*.sql
rm *
export GLOBIGNORE=

Setting GLOBIGNORE like this ignores php and sql from wildcards used like "ls *" or "rm *". So, using "rm *" after setting the variable will delete only txt and tar.gz file.
