Very helpful, thank you!

jonmcewen commented

Very useful for downgrading svn! What does the "brew switch" command do?

bekacho commented

I upgraded tmux from 1.6 to 1.8 and things suddenly stop to work, so I did not need to install it again since it was already installed , so to downgrade :

brew switch tmux 1.6

Thank you for the gist !

:+1:
@jonmcewen -- brew switch appears to simply update the symlink in /usr/local/bin to the specified formula version in the Cellar.

when i brew update
error: Your local changes to the following files would be overwritten by merge:
Library/Formula/subversion.rb
Please, commit your changes or stash them before you can merge.

Dude nice! I had 404 from all old versions of SVN but was able to manually drop in 1.7.11 into the svn folder and homebrew picked it up.

rainchen commented

git checkout -- Library/Formula/FORMULA.rb this line is not working. I have to replace the -- with the hash of latest commit to get this work

rainchen commented

I created a function version https://gist.github.com/rainchen/6363948
usage example:
$ brew-install ssh-copy-id 6.0p1

netsensei commented

Works perfectly! Thx!

hansenc commented

When trying to install subversion 1.7.x, I got "Error: No available formula for serf". The workaround was: 

$ brew tap homebrew/versions
$ brew install subversion17

as mentioned here. To switch back and forth between the two, you can use brew unlink and brew link.
