bash - List files not matching a pattern?

Question

Here's how one might list all files matching a pattern in bash:

ls *.jar

How to list the complement of a pattern? i.e. all files not matching *.jar?

Answer 1

Use egrep-style extended pattern matching.

ls !(*.jar)

This is available starting with bash-2.02-alpha1. Must first be enabled with

shopt -s extglob

As of bash-4.1-alpha there is a config option to enable this by default.
