what(1)
NAME
what − identify SCCS files
SYNTAX
what files
DESCRIPTION
The what command 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";
If f.c is compiled to yield f.o and a.out, then the command:
what f.c f.o a.out
This command will print:
f.c:
identification information
f.o:
identification information
a.out:
identification information
The what command 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.
RESTRICTIONS
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.
