NAME

what − identify SCCS files

SYNOPSIS

what files

DESCRIPTION

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

char ident[] = "@(#)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  command get(1), which automatically inserts identifying information, but it can also be used where the information is inserted manually.

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.
