Current Subversion revision command

Question

Is there a Subversion command to show the current revision number?

After svn checkout I want to start a script and need the revision number in a variable.

Answer 1

There is also a more convenient (for some) svnversion command.

Output might be a single revision number or something like this (from -h):

  4123:4168     mixed revision working copy
  4168M         modified working copy
  4123S         switched working copy
  4123:4168MS   mixed revision, modified, switched working copy

I use this python code snippet to extract revision information:

import re
import subprocess

p = subprocess.Popen(["svnversion"], stdout = subprocess.PIPE, 
    stderr = subprocess.PIPE)
p.wait()
m = re.match(r'(|\d+M?S?):?(\d+)(M?)S?', p.stdout.read())
rev = int(m.group(2))
if m.group(3) == 'M':
    rev += 1
