NAME

sccs-comb, comb - combine SCCS deltas

SYNOPSIS

/usr/ccs/bin/comb [ -os ] [ -csid-list ] [ -psid ] s.filename ...

DESCRIPTION

comb generates a shell script (see sh(1)) that you can use to reconstruct the indicated s.files. This script is writ- ten to the standard output. If a directory name is used in place of the s.filename argu- ment, the comb command applies to all s.files in that direc- tory. Unreadable s.files produce an error; processing con- tinues with the next file (if any). The use of `-' as the s.filename argument indicates that the names of files are to be read from the standard input, one s.file per line. If no options are specified, comb preserves only the most recent (leaf) delta in a branch, and the minimal number of ancestors needed to preserve the history.

OPTIONS

The following options are supported: -o For each `get -e' generated, access the reconstructed file at the release of the delta to be created. Other- wise, the reconstructed file is accessed at the most recent ancestor. The use of -o may decrease the size of the reconstructed s.file. It may also alter the shape of the delta tree of the original file. -s Generate scripts to gather statistics, rather than combining deltas. When run, the shell scripts report: the file name, size (in blocks) after combining, ori- ginal size (also in blocks), and the percentage size change, computed by the formula: 100 * ( original - combined ) / original This option can be used to calculate the space that will be saved, before actually doing the combining. -csid-list Include the indicated list of deltas. All other del- tas are omitted. sid-list is a comma-separated list of SCCS delta IDs (SIDs). To specify a range of deltas, use a `-' separator instead of a comma, between two SunOS 5.8 Last change: 1 Nov 1999 1 User Commands sccs-comb(1) SIDs in the list. -pSID The SID of the oldest delta to be preserved.

BUGS

comb may rearrange the shape of the tree of deltas. It may not save any space; in fact, it is possible for the recon- structed file to actually be larger than the original. SunOS 5.8 Last change: 1 Nov 1999 2
