WHAT(1)WHAT(1)NAMEwhat - identify SCCS files
SYNOPSISwhat [-s] files
DESCRIPTIONwhat 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 command get(1),
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.
SEE ALSOget(1), help(1)DIAGNOSTICS
Exit status is 0 if any matches are found, otherwise 1. Use help(1) for
explanations.
BUGS
It is possible that an unintended occurrence of the pattern @(#) could be
found just by chance, but this causes no harm in nearly all cases.
