WHAT(1)

NAME
what - identify files

SYNOPSIS
what name ...

DESCRIPTION
What searches the given files for all occurrences of the pattern which get (1) substitutes for %Z% (this is @(#) at this printing) and prints out what follows until the first `"', `>', newline, or null character. For example, if the C program in file `f.c' contains

    char iden___[] "@(#)identification information";

and f.c is compiled to yield `f.o' and `a.out', then the command

    what f.c f.o a.out

will print

    f.c:
    	identification information
    f.o:
    	identification information
    a.out:
    	identification information

What is intended to be used in conjunction with the SCCS command get (1), which automatically inserts identifying information, but it can also be used where the information is inserted manually.

DIAGNOSTICS
Use help (1) for explanations.

BUGS
It's possible that an unintended occurrence of the pattern @(#) could be found just by chance, but this causes no harm in nearly all cases.
