regex to get the rpm name version

[Asad]

Hi All ,

         I want to get a regex to actually get the rpm name and version for
comparison :


binutils-2.23.52.0.1-12.el7.x86_64",
compat-libcap1-1.10-3.el7.x86_64"
compat-libstdc++-33-3.2.3-71.el7.i686

(^[a-zA-Z0-9\-]*)\-\d'

First part of the regular expression is ^[a-zA-Z0-9\-]

which means search for anything that begins with a letter

(lower or upper) or a number up until you reach an

hyphen sign (‘-‘).

but it fails to match

compat-libstdc++-33-3.2.3-71.el7.i686

Please let me know what regex should i use to extract all 3

rpms.

Also let me know if there are web tools to build regex

Good websites for regex tutorials.




Thanks,
