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 ",
>, 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, 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 multi-byte
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 multi-byte 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.
