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 match

Answer 1

Another approach can be using ls -I flag (Ignore-pattern).

ls -I '*.jar'

Answer 2

If your ls supports it (man ls) use the --hide=<PATTERN> option. In your case:

$> ls --hide=*.jar

No need to parse the output of ls (because it's very bad) and it scales to not showing multiple types of files. At some point I needed to see what non-source, non-object, non-libtool generated files were in a (cluttered) directory:

$> ls src --hide=*.{lo,c,h,o}

Worked like a charm.

Answer 3

And if you want to exclude more than one file extension, separate them with a pipe |, like ls test/!(*.jar|*.bar). Let's try it:

$ mkdir test
$ touch test/1.jar test/1.bar test/1.foo
$ ls test/!(*.jar|*.bar)
test/1.foo

Looking at the other answers you might need to shopt -s extglob first.

Answer 4

One solution would be ls -1|grep -v '\.jar$'

Answer 5

ls | grep -v '\.jar$'

for instance.

Answer 6

Little known bash expansion rule:

ls !(*.jar)
