XENIX Programming SCCS: Source Code Control System
Searching for Strings
You can search for strings in files created from an s-file by using the what command.
The com mand searches for the symbol "#(@)" (the current value of the 96Z96 keyword) in
the given file and prints on the standard output all text immediately following the
symbol up to the next double quote ("), greater than ( > ), backslash {\), newline, or
(nonprinting) NULL character. For example, if the s-file s.demo.c contains the line
char id[] = "%Z%%M%: %1% " ;
and the command
get -r3.4 s.prog.c
is executed, then the command
displays
what prog.c
prog.c:
prog.c:3.4
You may also use what to search files not created by SCCS commands.
Comparing SCCS Files
You can compare two versions from a given s-file by using the sccsdiff command. This
command prints on the standard output the differences between two versions of the sfile.
The command has the form
sccsdiff -rS/01 -rS/02 s. filename
where -rSID1 and -rSID2 give the SIDs of the versions to be compared, and s.filename is
the name of the s-file containing the versions. The version SIDs must be given in the
order in which they were created. For example, the command
sccsdiff -r3.4 -r5.6 s.demo.c
displays the differences between versions 3.4 and 5.6. The differences are displayed in a
form similar to the XENIX diff command.
