I would suggest you change your approach and user the query mode of RPM to get
your information instead of build up a regexp:
rpm -qa --queryformat "%{NAME}\n"

Subject: regex to get the rpm name version
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,
