NAME
 what — search files for SCCS identifiers
DESCRIPTION
 The 
what utility reads each 
file operand and searches for sequences of the form “@(#)” as inserted by the source code control system. It prints the remainder of the string following this marker, up to a null character, newline, double quote, backslash, or “>” character.
If the -s option is specified, only the first occurrence of an identification string in each file is printed.
 
EXIT STATUS
 The what utility exits 0 if any matches were found, and 1 otherwise.
STANDARDS
 The what utility conforms to X/Open Portability Guide Issue 4, Version 2 (“XPG4.2”).
HISTORY
 The what command appeared in 4.0BSD.
BUGS
 As BSD is not licensed to distribute SCCS this is a rewrite of the what command which is part of SCCS, and may not behave exactly the same as that command does.
