Pipe Run
Pipe Run runs command and returns its standard output in one call:
require "pipe-run"
stdout = Pipe.run("date") # blocking
puts stdout # will print out for example 'Thu Feb 17 17:22:18 CET 2011'
stdout, errout = Pipe.run2("date") # blocking
puts stdout # will print out for example 'Thu Feb 17 17:22:18 CET 2011'
Asynchronous Use
In case, eventmachine is available, non-blocking run of the command is
possible using #run_nonblock or #run with block given, defined in
em-pipe-run file. So for example:
EM::run do
Pipe.run("date") do |stdout| # non-blocking
puts stdout # will print out for example 'Thu Feb 17 17:22:18 CET 2011'
end
Pipe.run2("date") do |stdout, errout| # non-blocking
puts stdout # will print out for example 'Thu Feb 17 17:22:18 CET 2011'
end
end
