BASH – Extracting Subversion Log
January 28th, 2010 @ 13:59:40 | BASH, Linux, Subversion
Subversion
Subversion (SVN) is a version control system initiated in 2000 by CollabNet Inc. It is used to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly-compatible successor to the widely used Concurrent Versions System (CVS). Subversion is well-known in the open source community and is used on many open source projects.
Subversion was started in 2000 as an effort to write a free version control system which operated much like CVS but with fixed bugs and misfeatures in CVS. By 2001, Subversion was sufficiently developed to be capable of hosting its own source code. More information, including this above paragraphs, is here.
Why This Script?
Per SVN Book:
svnlookis a tool provided by Subversion for examining the various revisions and transactions in a repository. No part of this program attempts to change the repository—it’s a read-only tool.svnlookis typically used by the repository hooks for reporting the changes that are about to be committed (in the case of the pre-commit hook) or that were just committed (in the case of the post-commit hook) to the repository. A repository administrator may use this tool for diagnostic purposes.
This BASH script uses svnlook and extends its usage to produce an elegant display of log of a Subversion repository.

Have you ever considered about adding a little bit more than just your articles? I mean, what you say is important and everything. But think of if you added some great pictures or video clips to give your posts more, “pop”! Your content is excellent but with images and clips, this website could definitely be one of the most beneficial in its niche. Good blog!
