sc2sbcs - convert an SCCS file to a new SBCS file.
sc2sbcs converts an existing SCCS s-file
to a new SBCS s-file.
Version and history information is extracted from the SCCS s-file
and used to create a new SBCS s-file.
The information that is preserved includes the original SID,
delta sequence number, date and time, author,
list of MRs and comments for all deltas, actual and removed.
The file descriptive text, user list and flags are also preserved.
Predecessor sequence numbers reflect the underlying differencing
implementation and are in general not preserved.
An application should not rely on predecessor sequence numbers.
The information on included or excluded deltas is not preserved, because
SBCS has no use for it. This does not affect the integrity of any of
the versions transformed. If the new file were reconverted to SCCS,
using sb2sccs, the new SCCS file may be larger than the original
one because storage efficiences realized with -i and -x cannot
be recreated. Again, this does not affect the integrity of any version.
The SCCS character-count statistics for deltas is regenerated,
except for removed deltas.
sc2sbcs generates an sh(1) and awk(1) script and then runs it.
It is possible to run the command to simply generate the intermediate
Don't run the script. The intermediate sh executable script is
preserved as sc2sb.sh and it is not run. sc2sbcs will not
overwrite an existing sc2sb.sh file.
Silent mode. Suppress all non-error information.
Normally some status information is printed to standard output.
Verbose mode. Allow all SBCS and SCCS commands used by the script
to print their usual messages to standard out.
- -fw comp
Set compression scheme to comp in the new sbcsfile. If comp is null,
do not use compression in the resulting SBCS file.
See nadmin(1) for a review of possible comp values.
- -fy diff
Set differencing scheme to diff in the new sbcsfile. If diff is null,
do not use differencing in the resulting SBCS file.
See nadmin(1) for a review of possible diff values.
Only in exceptional circumstances should differencing be turned off.
- -g sccs-get-cmd
Full path of the SCCS get command to use to retrieve versions
from the SCCS file.
That path is then also used for the SCCS admin, delta and prs
All temporary files are created in the directory
specified by TMPDIR, TEMP, TMP or the sbcsenv variable tmpdir.
They are removed before completion of sc2sbcs.
The SCCS g-file is also created and cannot pre-exist.
The SBCS g-file, p-file, z-file and Z-file are all created during
the conversion. They are removed at the end of the conversion.
