Although what tinkster stated is correct, that will just produce a bunch of names in almost no time to read.
You can type:
rpm -qa | grep «string»
= looks for the string you specify (without «») within the installed packages. For examples: rpm -qa | grep libstdc++
, lists any installed package that contains the string libstdc++
rpm -qa | more
= lists all the files but pauses each time your screen is filled. By pressing enter
you advace one line, space bar
you advance one page and by pressing q
you quit at any time.
BTW, using the |
is called piping. It's sending the output from one program (in this case rpm -qa) to another one that filters it. There are a lot of combinations as you might suppose.
Hope that helps
