Lets take this command for example$ time ssh ec2 lswww appsreal    0m0.554suser    0m0.004ssys     0m0.000s$ time ssh ec2 ls 1>/dev/nullreal    0m0.554suser    0m0.004ssys     0m0.000s$ time ssh ec2 ls 2>/dev/nullwww appsreal    0m0.554suser    0m0.004ssys     0m0.000sClearly ls output come from fd 1. What about time output. Which file descriptor does it use? How can I find it?Other than this, instead of redirectly them individually, how can I redirect all of them at once.. i.e. all>/dev/null. I am not looking for 1>/dev/null 2>&1...
How to get file descriptor number of a output and how to redirect all of them at once
