Installing
mssh is a rubygem: gem install mssh. http://rubygems.org/gems/mssh
BUGS/TODO
- Optionally Incorporate stderr into -c, with $?
- allow commandline manipulation of ssh args
- factor out redundancy between bin/mssh and bin/mcmd (cli module?)
- incorporate range / foundation lookup syntax for -r
- json output mode
- to-file output mode
- lots of rough spots, not super slick yet
- needs testing real bad. 0.1 release
