Introduction

Finding the version number of a particular piece of software can be tricky. It implies that you know where the software is located in the first place! This page tries to solve this problem.
The usual method is:

Look at the local package manager. That's usually the most reliable method. It helps a lot to locate a specific package (for instance Motif or MPI or ...) and to get its version.
Commands that can help: whereis (don't take into account your PATH), which (usually a csh command), type (a ksh command), man -k, what (to extract a SCCS tag)
For an executable, try these flags: -V, -v, -version, --version, -what, +version
For a library, look for a possible symbolic link in the relevant directory which may give you an hint. For instance, for libc, try ls -l /usr/lib/libc*. Failing that, try strings on the library file.

*Package managers on Unix*
Operating system	Main command	List installed packages

Linux Debian	`dpkg`	`dpkg -l`
Linux (Slackware distribution)	`pkgtool`	`pkgtool` `ls -l /var/log/packages/`
Cygwin	Graphic installer ("setup.exe")	`cygcheck -c`
Solaris	`pkginfo`	`pkginfo` `grep xxx /var/sadm/install/contents`
Irix	`versions`	`versions`
Compaq (Digital) Unix	`setld`	`setld -i`
AIX	`lslpp`	`lslpp -l`
