How to search ONLY in package names, without descriptions?

indianahorst · 2008-09-04 15:24:59

Hello!

I would like to know how I can search with pacman only in the package names, without searching descriptions?

For example, searching for the rar package (pacman -Ss rar) gives me tons of results with hundreds of packages, where "library" occurs in the description.

I have already read the pacman manual page, but I couldn't find anything suitable.

find /var/abs -type d -name *rar*

You could pacman -Sl core extra community | grep rar.

How about:

pacman -Slq | grep <package>

Woops, yeah, I meant -Slq.

perl -e '$search = "rar";$output=`pacman -Ss $search`;while($output=~/^(\S.*?\Q$search\E.*?\n(?:\s.*\n)*)/mgi){print $1}'

This does the normal "pacman -Ss whatever" search, but then it checks that the search term is in the package name. Just replace "rar" in "$search = "rar" with whatever you want to search for.

I tried to make it work with grep using -P, but I still don't know how to make it case-insensitive then ("-i" doesn't seem to work with perl regexes). Here it is anyway though:

pacman -Ss rar | grep -P "^\S.*?rar(?:.*|\n)*?(?=\n\S)"

Aside from being case-sensitive, you also have to replace both instances of "rar" with your search term.

Here's a script version that you can run from the command line:

#!/usr/bin/perl
use strict;
use warnings;


my $search = "@ARGV";
my $output = '';

open(my $pipe,'-|',"pacman -Ss $search") or die "Unable to create pipe to pacman: $!\n";
while (defined(my $line=<$pipe>)){$output.=$line;}
close $pipe;
while($output=~/^(\S.*?\Q$search\E.*?\n(?:\s.*\n)*)/mgi){print $1};

Save it as "search_pkgnames", make it executable, then invoke it with your search term: search_pkgnames rar

Hope this helps.

You can even alias the above script to work with pacman, i.e. alias "pacman -Sp" /path/to/search_pkgnames.

I would suggest something other than "-Sp" as that's for printing the URIs... perhaps "pacman -Ss --by-name" instead.

Interesting idea btw... I hadn't even considered making aliases like that.

Oops, you're right, I had forgotten about the -p flag. How about pacman -Sss?
