The other day I wanted to figure out when a particular line in WordPress was changed. I wanted to know this so I could find the commit message and ticket that went along with it so I could figure out the reasoning behind the change. How do you go about doing that though?
It turns out that svn blame is the command you want. It will output something like this:
$ svn blame http://svn.red-bean.com/repos/test/readme.txt 3 sally This is a README file. 5 harry You should read this.
So the first line was last modified by sally in revision 3 and the second line was last modified by harry in revision 5. Awesome huh?
