svnversion — Summarize the local revision(s) of a working copy.
svnversion is a program for summarizing the revision mixture of a working copy. The resultant revision number, or revision range, is written to standard output.
It's common to use this output in your build process when defining the version number of your program.
TRAIL_URL, if present, is the
trailing portion of the URL used to determine if
WC_PATH itself is switched
(detection of switches within
WC_PATH does not rely on
TRAIL_URL).
When WC_PATH is not defined,
the current directory will be used as the working copy path.
TRAIL_URL cannot be defined if
WC_PATH is not explicitly
given.
Like svnserve, svnversion has no subcommands, it only has options.
--no-newline (-n)Omit the usual trailing newline from the output.
--committed (-c)Use the last-changed revisions rather than the current (i.e., highest locally available) revisions.
--help (-h)Print a help summary.
--versionPrint the version of svnversion and exit with no error.
If the working copy is all at the same revision (for example, immediately after an update), then that revision is printed out:
$ svnversion 4168
You can add TRAIL_URL to make
sure that the working copy is not switched from what you
expect. Note that the WC_PATH
is required in this command:
$ svnversion . /repos/svn/trunk 4168
For a mixed-revision working copy, the range of revisions present is printed:
$ svnversion 4123:4168
If the working copy contains modifications, a trailing "M" is added:
$ svnversion 4168M
If the working copy is switched, a trailing "S" is added:
$ svnversion 4168S
Thus, here is a mixed-revision, switched working copy containing some local modifications:
$ svnversion 4212:4168MS
If invoked on a directory that is not a working copy, svnversion assumes it is an exported working copy and prints "exported":
$ svnversion exported
