【PE】Linux下的svnversion命令以及SVN版本号获取方法

###Date: 2017/9/23

在makefile脚本中检索出svn版本号：

$(shell svnversion -n|grep  [0-9]*[A-M] $(ROOT_IDR))

or:      $(shell svn info|grep Revision|awk '{print $2}')

下面是整理的Subversion官网上关于svnversion命令的使用方法：

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.

--quiet (-q)

Requests that the program print only essential information while performing an operation.

--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

svnversion will also inform you if the target working copy is sparsely populated (see the section called “Sparse Directories”) by attaching the 'P' code to its output:

$ svnversion
4168P

Thus, here is a mixed-revision, sparsely populated and switched working copy containing some local modifications:

$ svnversion
4123:4168MSP
