Removing version numbers from … well anything

This one liner can remove the version numbers from any string (providing they start with a hyphen and a digit).

The example below is specific to RedHat as shows how to remove the version numbers from a list of installed packages produced by  rpm , but it will work with any command that produces output ending in a version numbers on each line that begins with a hyphen.

for _string in $(rpm -qa | sort); do echo ${_string//-[0-9]*/}; done
