UnixCommander
This is a gem used to run unix commands ruby style. Normally to run a command we have to do something like:
%x[cat file | tail -n10 | grep 'something']
The goal is to be able to do it with a more rubyesque way.
Installation
Add this line to your application's Gemfile:
gem 'unix_commander'
And then execute:
$ bundle
Or install it yourself as:
$ gem install unix_commander
Usage
With this gem you will be able to run unix commands this way:
require 'unix_commander'
comm = UnixCommander::Command.new
comm.cat("file").tail("-n10").grep("'something'").run
You can use redirection too
require 'unix_commander'
comm = UnixCommander::Command.new
comm.cat("file").tail("-n10").grep("'something'").out_to("my_file").err_to("/dev/null")
You don't have to run the commands right away, we can create a command and run it whe we see fit:
require 'unix_commander'
comm = UnixCommander::Command.new
comm = comm.cat("file").tail("-n10").grep("'something'")
#...
comm.run
Also you can run commands remotely using ssh using run_ssh instead of run. (Syntax: run_shh(username, password,server) or run_ssh(username,password) to connect to localhost)
require 'unix_commander'
comm = UnixCommander::Command.new
comm.cat("file").tail("-n10").grep("'something'").run_ssh("Batou99","secret","remote_server")
After running a command you can access it output using out, err or both
require 'unix_commander'
comm = UnixCommander::Command.new
comm.cat("file").tail("-n10").grep("'something'").run_ssh("Batou99","secret","remote_server").out
# Or
comm.cat("file").tail("-n10").grep("'something'").run_ssh("Batou99","secret","remote_server").err
# Or
comm.cat("file").tail("-n10").grep("'something'").run_ssh("Batou99","secret","remote_server").both
