List files not matching a pattern?
Little known bash expansion rule:
Use egrep-style extended pattern matching.
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.
ls | grep -v '\.jar$'
With an appropriate version of
find, you could do something like this, but it's a little overkill:
find . -maxdepth 1 ! -name '*.jar'
find finds files. The
. argument specifies you want to start searching from
., i.e. the current directory.
-maxdepth 1 tells it you only want to search one level deep, i.e. the current directory.
! -name '*.jar' looks for all files that don't match the regex
Like I said, it's a little overkill for this application, but if you remove the
-maxdepth 1, you can then recursively search for all non-jar files or what have you easily.
