Notice that "Linux" does not have a standardized package manager at all. In fact Linux is basically a kernel, not an OS and what makes it a complete OS is a bunch of GNU-tools added to it. Whoever does that adding choses and selects what he deems relevant and this way different "distributions" come to pass.

Because of this there is no package manager and the different distributors (the people/companies creating the distributions) created their own package managers. The two probably most widespread are rpm (RedHat Package Manager), developed by RedHat and used by: RedHat, SuSE, CentOS, Fedora, RHEL and perhaps a few more and apt, developed by Debian and used an all Debian-based distributions (Debian, *Ubuntu, Mint, etc.). There are other package managers either, but there are even distributions without a package manager (Gentoo and ArchLinux, IIRC) at all.

If you want an agent-like software to create a software inventory over various systems you will either have to limit which distributions (more precisely: which package managers) you want to support or perhaps write your own.

I hope this helps.

NAME

       whohas - find packages in various distributions' repositories

SYNTAX

       whohas [--no-threads] [--shallow] [--strict] [-d Dist1[,Dist2[,Dist3 etc.]]] pkgname

DESCRIPTION

       whohas  is  a command line tool to query package lists from the Arch, Debian, Fedora, Gentoo, Mandriva, openSUSE, Slackware (and linuxpack-
       ages.net), Source Mage, Ubuntu, FreeBSD, NetBSD, OpenBSD, Fink, MacPorts and Cygwin distributions.

OPTIONS

       --no-threads
	      Don't use multiple threads to query package lists (will be much slower)

       --shallow
	      Limit to one call per server. Faster, but loses some information, typically package size and release date.

       --strict
	      List only those packages that have exactly pkgname as their name.

       -d Dist1[,Dist2[,Dist3 etc.]]
	      Queries only for packages for the listed distributions.  Recognised  values  for	Dist1,	Dist2,	etc.  are  "archlinux",  "cygwin",
	      "debian", "fedora", "fink", "freebsd", "gentoo", "mandriva", "macports", "netbsd", "openbsd", "opensuse", "slackware", "sourcemage",
	      and "ubuntu".

       pkgname
	      Package name to query for

FILES

       whohas uses various files in ~/.whohas to cache package lists for some distributions.
