I had a problem, normally i checkout an svn folder of my dotfiles and create symlinks to these files, however sometimes this isn't possible, as the end machines dont have svn installed, or cant reach the internet. I've found recently a more useful use case is being able to checkout to a single machine and push out the dot files from there, having 1 master set of files, and one master ssh machine per location. Here's what I came up with, feel free to reuse if it helps you.

  
#!/bin/bash
#########################################################################################
# Small script to push out some common files to various machines in differing locations #

work_machines=`echo myusername@{hostnameA,hostnameB}`
home_machines=`echo myuser@{hostnameA,hostnameB}`
