How do you check for a specific rpm if it is installed? You can do it this way:
rpm -q <package name>
This way you need to enter full name So you can do this:
rpm -qa|grep -i <part of package name>
But it's slow
Then why don't you make scripts to save rpm list. This will speed up the query:
1. Script for saving rpm list for faster reference (name it rpmlist):
#!/bin/bash rpm -qa >~/rpmlist
2. Script for searching in rpmlist(name it rpmfind):
#!/bin/bash grep -i $1 ~/rpmlist
