[julia-users] How to capture the output of a system command?

[J Luis]

Ok, I've spend about an hour around "run" "open", "run(pipeline(..." but no 
way.
In Matlab I would do

    [status, cmdout] = system(cmd);

but in Julia the most a can reach is to run the command

com = "C:/programs/GraphicsMagick/gm.exe compare -density 200 ...

   run(`com')

but I need the result of that execution. 
How to?

Thanks
