Command to display executable version

[Gary Cooper_1]

I'm sure I came across a shell (ksh) command that displayed the version of an executable, something along the lines of...

$ <show_version> /usr/bin/diff

But I can't for the life of me remember what it was.

I'm not looking for the regular 'swlist', but something that looks inside the file (which is supplied as a parameter).

Many thanks,

Gary

The command you're looking for is 'what'.

# what /usr/bin/diff
/usr/bin/diff:
diff.c $Date: 2002/06/03 03:20:39 $Revision: r11.11/2 PATCH_11.11 (PHCO_26907)

In addition to 'what', the program 'ident' can be useful in certain scenarios, e.g. when the binary is built using sources controlled under RCS.
