SLEX

slex is a simple binary that allows you to run a command on multiple hosts via SSH. It is very similar to fabric except that it is written in Go so you don't have to have python installed on your system and you don't have to write a script or configuration files if you do not want to.

Building

To build slex you must have a working Go install then you can run:

go get -u github.com/crosbymichael/slex
