Shr

Shr tries to make controlling subprocess easier in Ruby.

It can be writea shell command as like a Ruby's method and capture subprocess output.

This is a port of Python's sh.

gem install shr

Require when needed

require 'shr'

Create instance by Shr#shell

sh = Shr.shell

Run command and capture subprocess output.

puts sh.ls

Redirect [to|from] file

sh.ls > '/tmp/ls_result.txt'
puts sh.cat < '/tmp/ls_result.txt'

Pipes are represented by the chain method

# cat -n /tmp/ls_result.txt | sort -r
puts sh.cat(:n, '/tmp/ls_result.txt').sort(:r)

Bake and run new command

sh.bake(:catn,  :cat   [:n])
sh.bake(:sortr, :sort, [:r])
puts sh.catn('/tmp/ls_result.txt').sortr
