SOURCE CODE CONTROL SYSTEM (SCCS)

SCCS Overview
The source code control system allows versions of a program to be stored in a special file, so that any version may be retrieved. There are a few commands involved (not all of them listed here). All source code files start with 's.'

get -r<revision> <source code file>

- get a program out of source code to read only. Missing out the -r flag gets the most recent version. e.g.
$ get $SCUK/s.parser.c # extracts file parser.c from source code file $SCUK/s.parser.c as read only. See get -e for editing.

get -e <source code file>

- get a piece of code out for edit, so that the code may be modified and a new version created using 'delta'. e.g.
$ get -e $SCUK/s.parser.c # extracts file parser.c from source code file $SCUK/s.parser.c for editing. See get for read-only.

delta <source code file>

- you must be in the directory with the modified piece of code when you execute this command. This adds the latest version to the source code file. e.g.
$ delta $SCUK/s.parser.c # writes file parser.c to the source code file $SCUK/s.parser.c . See get -e for information on how to extract the file from source code.

prs <source code file>

- show comments/details on source code file.

admin -r <revision no> -i <program> <source code file>

- create a new source code file with progam. -r specifies the initial revision of the program and may be missed out (default is 1.1 I think). Must be spaced correctly! admin is also used for sccs administration, but it gets to fear and loathing time pretty fast. e.g.
admin -iparser.c $SCUK/s.parser.c # creates a new source code file called $SCUK/s.parser.c from the file parser.c

unget <source code file>

- cancels a get -e
