If you just want to get a list of files in a directory, Ruby
provides the portable Dir#entries method.
I don’t know how to
redirect the output into a gtk text editor, not in the original
terminal window.
I’m sure the gtk text editor has some #append or #insert method
which lets you add text to it. Use that.
Something like
sbtn.signal_connect(“pressed”) {
lsproc = IO.popen(‘ls’)
p Process.waitpid(lsproc.pid)
p $?
}
… is portable, but still does not redirect the output.
IO.popen(‘ls’) do |f|
puts f.read
end
If you want to “pipe” some data to the subprocess:
request = “i want ice cream!”
IO.popen(‘cat’, ‘r+’) do |f|
f.write request
f.close_write
response = f.read
puts “cat said: #{response}”
end
