NAME

what — get SCCS identification information

SYNOPSIS

what [-s] file...

DESCRIPTION

The what command searches the given files for all occurrences of the pattern that get(1) substitutes for %Z% (currently @(#) 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 ident[] = "@(#)identification information";

and f.c is compiled to yield f.o and a.out, 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 SCCS get command (see get(1)) which automatically inserts identifying information, but it can also be used where the information is inserted manually.

Options

what recognizes the following option:

-s

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

EXTERNAL INFLUENCES

Environment Variables

LC_CTYPE determines the interpretation of the pattern substituted for %Z% as single- and/or multibyte characters.

LC_MESSAGES determines the language in which messages are displayed.

If LC_CTYPE or LC_MESSAGES is not specified in the environment or is set to the empty string, the value of LANG is used as a default for each unspecified or empty variable. If LANG is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable contains an invalid setting, what behaves as if all internationalization variables are set to "C". See environ(5).

International Code Set Support

Single-byte and multibyte character code sets are supported.

DIAGNOSTICS

Exit status is 0 if any matches are found, otherwise 1. Use help for explanations (see sccshelp(1)).

WARNINGS

The pattern @(#) may occasionally appear unintentionally in random files, but this causes no harm in nearly all cases.

STANDARDS CONFORMANCE

what: SVID2, SVID3, XPG2, XPG3, XPG4
