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

 SYNOPSIS


 "/usr/ccs/bin/sccsdiff \c  [ -p "] \c  -r "sid \c  -r "sid \c  [ diff-options "] 

 " [" -N\c  bulk-spec "] \c  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:




 13
 -p Pipe output for each file through 
 pr (1). 




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





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


 -N bulk-spec Processes a bulk of SCCS history files.
This option allows 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:



 10
 none 

The following path specifier types are supported:

 10
 -N 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.


 -Ns. 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.


 -N dir 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.


 -N dir /s. 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
 \s-1SCHILY\s+1 extension that does not exist in historic
 sccs implementations.








 0
 -V 

 -version 

 --version 

Prints the
 sccsdiff version number string and exists.
This option is a
 \s-1SCHILY\s+1 extension that does not exist in historic
 sccs implementations.


 ENVIRONMENT VARIABLES

See
 environ (5) 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 . 




 SCCS_NO_HELP 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 .

 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 is maintained by J\*org Schilling.
