WHAT(1) — Silicon Graphics
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 SCCS command get(1), which automatically inserts identifying information, but it can also be used where the information is inserted manually.
EXAMPLE
If "test1.c" has the following string
char v[] = "@(#)1 test1.c 2";
typing
what test1.c
would print the following:
test1.c:
1 test1.c 2

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.
