Reviewing Pending Changes: sccs diffs

Changes made to a checked-out version, which are not yet checked in, are said to be pending. When editing a file, you can find out what your pending changes are using sccs diffs. The diffs subcommand uses diff(1) to compare your working copy with the most recently checked-in version.

$ sccs diffs program.c
------ program.c ------ 
37c37 
<		      if (((cmd_p - cmd) + 1) == l_lim) { 
--- 
>	      	if (((cmd_p - cmd) - 1) == l_lim) { 

Most of the options to diff can be used. To invoke the -c option to diff, use the -C argument to sccs diffs.
