Capturing Output of a Command from an Extension

[xtranophilist aaa <xtranophilist gmail com>]

How do I capture the output of a command?

One way could be running command with Util.spawn that redirects output to a file using '>' or using tee command. And then read the file with GLib.file_get_contents().

But I couldn't make the command output to file work right.

There should be a way to directly get output into a variable as string.

Please help!

Thank you :)
