I want to write a shell script in bash to deploy websites from an svn repository. When I deploy a website, I name the exported directory website_name-Rrevision_number. I'd like the bash script to automatically rename the exported directory, so it needs to learn the current revision number from the export directory. If I run
$> svn info http://svn-repository/trunk
Path: trunk
URL: http://svn-repository/mystery/trunk
Repository Root: http://svn-repository/mystery
Repository UUID: b809e6ab-5153-0410-a985-ac99030dffe6
Revision: 624
Node Kind: directory
Last Changed Author: author
Last Changed Rev: 624
Last Changed Date: 2010-02-19 15:48:16 -0500 (Fri, 19 Feb 2010)
The number after the string Revision: is what I want. How do I get that into a bash variable? Do I do string parsing of the output from the svn info command?

To find information about the history of a file or directory, use the svn log command. svn log will provide you with a record of who made changes to a file or directory, at what revision it changed, the time and date of that revision, and, if it was provided, the log message that accompanied the commit.
If you want to write a script which requires no input, you should use the official Subversion command line client instead. checkout a working copy in REV revision: svn checkout --revision REV https://svn.example.com/svn/MyRepo/trunk/ svn checkout https://svn.example.com/svn/MyRepo/trunk/@REV.
As you saw in the section called “Revisions”, revision numbers in Subversion are pretty straightforward—integers that keep getting larger as you commit more changes to your versioned data.
Using the latest versions of Subclipse, you can actually view them without using the cmd prompt. On the file, simply right-click => Team => Switch to another branch/tag/revision.
Use svnversion. This will output the revision number/range with minimal additional cruft

REVISION=`svn info http://svn-repository/trunk |grep '^Revision:' | sed -e 's/^Revision: //'`
It's simple, if inelegant.
