## Name

svnversion — Summarize the local revision(s) of a working copy.

## Synopsis

    svnversion [OPTIONS] [WC_PATH [TRAIL_URL]]

## Description

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 whether `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.

## Options

Like svnserve, svnversion has no subcommands—only options:

`--no-newline` (`-n`)

  Omits the usual trailing newline from the output.

`--committed` (`-c`)

  Uses the last-changed revisions rather than the current (i.e., highest locally available) revisions.

`--help` (`-h`)

  Prints a help summary.

`--version`

  Prints the version of svnversion and exit with no error.

## Examples

If the working copy is all at the same revision (e.g., immediately after an update), then that revision is printed out:

    $ svnversion
    4168

You can add `TRAIL_URL` to make sure the working copy is not switched from what you expect. Note that the `WC_PATH` is required in this command:

    $ svnversion . /var/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
