NAME

what − print identification strings

SYNOPSIS

what [−s] files

DESCRIPTION

what searches the given files for all occurrences of the pattern that the get command 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

#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

prints

f.c:
identification information

f.o:
identification information

a.out:
identification information

what is intended to be used in conjunction with the get command, which automatically inserts identifying information, but it can also be used where the information is inserted manually.  Only one option exists:

−s Quit after finding the first occurrence of pattern in each file.
