Looking for the most convenient grep command to list fields from two stdout entries

MostViktorious · 11-03-2013, 05:19 PM

Hello, my goal is to be able to search an arbitrary amount of packages using

Code:

apt-cache show package1 package2

... and grep all of those entries with

Code:

| grep "Package\|Size"

for instance.

The current solution appears to be extremely inefficient and I would like to believe there's another method with manipulating cat and/or echo (I'm not too good with those yet.)

i.e

This produces exactly what I want:

Code:

apt-cache show gparted | grep "Package/|Size" && apt-cache show partitionmanager | grep "Package\|Size"

How do I reproduce this more efficiently?

define "more efficiently"

your grep works just fine

Code:

apt-cache show gparted partitionmanager | grep "Package\|Size"
