Package Manager Search Commands

By Michael Altfield, on December 23rd, 2010

In a given week, I touch maybe a half dozen different Operating Systems/Distributions. Some are similar to others (centos, rhel), some–not so much (solaris). The common commands are easy enough to remember ( @ls@ vs @dir@ ), but I always forget how to search through each OS’s package manager for a software package. For my reference (and perhaps yours?) here’s a list for each of the OSs’ package managers I use frequently:

yum – RHEL/CentOS

yum list

apt – Debian/Ubuntu

apt-cache search

pacman – Arch

pacman –sync –search pacman -Ss

portage – Gentoo

emerge –search # pkg names only emerge –searchdesc # pkg names & descriptions emerge -S # alias of –searchdesc

Enabling SELinux strict on RHEL5

By Michael Altfield, on July 6th, 2009

I’ve been playing around with SELinux at work recently. Not surprisingly, I was struggling to get SELINUXTYPE=strict to work properly. Unfortunately, all “google results for ‘enabling selinux strict’ would return were dead ends. People would enable selinux strict, kernel panic, and ‘fix’ it by disabling selinux.

Well, a co-worker of mine *was* able to successfully enable selinux’s strict policy on RHEL5 (CentOS 5). He gave me this guide to post to the world for others to see how (thanks Mykola):

Install “build-essential” on RHEL/CentOS and OpenSolaris

By Michael Altfield, on June 13th, 2009

Debian

If you want to be able to compile packages in debain/ubunutu, you can issue the following command:

apt-get install build-essential

 

Red Hat

If you want to be able to compile packages in red hat/centos, you can issue the following command:

yum install make gcc gcc-c++ kernel-devel

…or, if you don’t care about maintaining a small footprint, you can get *all* of the development packages (including X devs–eww):

yum groupinstall "Development Tools"

 

Open Solaris

If you want to be able to compile packages in open solaris, you can issue the following command:

pkg install SUNWgcc Michael Altfield
