I have a script that connects to an FTP server and while doing so prints out a load of junk.

Is there a way to 'mute' the ouput of the script, similar to windows @echoff? I saw on another question very similar to mine, not the same though that you could use scriptname >/dev/null. When I put this in my program, obviously replacing scriptname with the name of the script, I got a command not found error message.

Does anyone have any idea why this might be happening.

  • Because of a typo, for example. Or because the script calls a command that's not available, in which case the shell will print the error message to stderr as opposed to stdout (which is not redirected by > /dev/null). Without knowing your code and the way you call it, all is guesswork. Commented Mar 2, 2015 at 21:12

If you mean you want to redirect all output to /dev/null from within the script, rather than when you execute the script, you can do this:

#!/bin/bash
echo Hi

and run that, like this

./script

then do this

#!/bin/bash
exec 1> /dev/null
echo Hi

and run it again exactly the same way, and see that the output is discarded.

You wouldn't put that in your program, but rather, would use it when calling your program. On the command line:

$ scriptname >/dev/null
