I need a solution that simulates the rpm -q command as follows:
The linux rpm command returns only the first occurance of what you are looking for.
if you have cups installed
rpm -q cups returns
even though cups-libs-1.5.2-9.fc16.x86_64 is installed.
I loaded an array with the output of rpm -qa
I need to do a search on that array (data strucuture is not important to me, it can be anything) using cups as the search string and have it only return
and not anything else with cups in the string anywhere in the array.
This will effectivly simulate the "rpm -q string" command.
It also must return an empty set indication if only
cups-1.5.2-9.fc16.x86_64 does not.
And of course this will work with any string matched against the array. Not just cups.
It's ok if the grep or match or search returns a duplicate.
that is if cups-1.5.2-9.fc16.x86_64 is in the rpm data array twice its ok if it returns it into output of another array.
I have been trying grep and regular expresions, but my regex is not up to solving this particular problem.
Thanks, in advance.
