NAME

sccs-sccsdiff, sccsdiff - compare two versions of an SCCS file

SYNOPSIS

/usr/ccs/bin/sccsdiff 
[-p] 
-rsid 
-rsid 
[diff-options]


    [-N
bulk-spec] 
s.filename

DESCRIPTION

sccsdiff compares two versions of an SCCS file and displays the differences between the two versions. Any number of SCCS files may be specified. The options specified apply to all named s.files.

OPTIONS

The following options are supported:

Pipe output for each file through pr(1).

Specify a version corresponding to the indicated SCCS delta ID (SID) for comparison. Versions are passed to diff(1) in the order given.

Pass options to diff(1), including: -b, -c, -e, -f, -h, -u, -C number, -U number, and -D string.

Processes a bulk of SCCS history files. This option allows one to do an efficient mass processing of SCCS history files.

The bulk-spec parameter is composed from an optional list of flag parameters followed by an optional path specifier.

The following flag types are supported:

The following path specifier types are supported:

The file name parameters to the sccsdiff command are not s.filename files but the names of the g-files. The s.filename names are automatically derived from the g-file names by prepending s. to the last path name component. Both, s.filename and the g-file are in the same directory.
The file name parameters to the sccsdiff command are s.filename files. The the g-files names are automatically derived by removing s. from the beginning of last path name component of the s.filename. Both, s.filename and the g-file are in the same directory.
The file name parameters to the sccsdiff command are not s.filename files but the names of the g-files. The s.filename names are put into directory dir, the names are automatically derived from the g-file names by prepending dir/s. to the last path name component.
The file name parameters to the sccsdiff command are s.filename files in directory dir. The the g-files names are automatically derived by removing dir/s. from the beginning of last path name component of the s.filename.

A typical value for dir is SCCS.

In order to overcome the limited number of exec(2) arguments, it is recommended to use `−' as the file name parameter for sccsdiff(1) and to send a list of path names to stdin.

This option is a SCHILY extension that does not exist in historic sccs implementations.

-V
Prints the sccsdiff version number string and exists.

This option is a SCHILY extension that does not exist in historic sccs implementations.

ENVIRONMENT VARIABLES

See environ(7) for descriptions of the following environment variables that affect the execution of sccsdiff(1): LANG, LC_ALL, LC_COLLATE, LC_CTYPE, LC_MESSAGES, and NLSPATH.

If set, sccsdiff(1) will not automatically call help(1) with the SCCS error code in order to print a more helpful error message. Scripts that depend on the exact error messages of SCCS commands should set the environment variable SCCS_NO_HELP and set LC_ALL=C.

DIAGNOSTICS

If the two versions are the same.

Use the SCCS help command for explanations of other messages. See sccs-help(1).

AUTHORS

The SCCS suite was originally written by Marc J. Rochkind at Bell Labs in 1972. Release 4.0 of SCCS, introducing new versions of the programs admin(1), get(1), prt(1), and delta(1) was published on February 18, 1977; it introduced the new text based SCCS v4 history file format (previous SCCS releases used a binary history file format). The SCCS suite was later maintained by various people at AT&T and Sun Microsystems. Since 2006, the SCCS suite has been maintained by Joerg Schilling and the schilytools project authors.
