vdiff - display line-by-line differences between versions of files
vdiff [ diff-options ] [ -base path ] [ -P ] files ..
vdiff is a differential comparator for file versions that are stored in shapeTools' object base, AtFS. The functionality of vdiff is very similar to the diff command on your host. All options and switches that are recognized by diff can also be specified for vdiff.
The arguments to vdiff can either be a single filename, or a pair of version identifiers. If only a filename is specified, vdiff prints the differences between the specified file and the most recent version of this file that is stored in the AtFS object base. A file can be compared to any stored version by specifying the version as first, and the filename as second argument. If both arguments are version identifiers, the difference between these two versions is printed.
Differences between files and versions can be printed in any style that is supported by the local diff program.
Version identifiers consist of the filename, and a version number
or alias name for a version, enclosed in brackets. Example:
retrieve.c[4.22] or retrieve.c[Rel-4.1]
vdiff creates temporary copies of the versions that shall be compared, invokes the diff command, and finally removes the temporary copies.
