what - get SCCS identification information
what [-s] file ...
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
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
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.
what recognizes the following option:
-s Quit after finding the first occurrence of pattern in
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).
