How to hide terminal output when executing a command?

If you can avoid writing stuff in the console, it depends on how output from the program is created. If it is streamed to standard output, then it is just enough to do

$ eclipse >/dev/null

and no output should be made.

To suppress error messages as well:

$ eclipse >/dev/null 2>&1

Or in bash, simply:

$ eclipse &>/dev/null

But if they do it somehow differently then it might be a problem to stop it from writing in the console.

if possible use the solution given by MuffinStateWide

You can create a bash function that will alias a command name and add some extra functionality to achieve what you are asking for.

For example: let's say you want to launch gvim (a gui text editor) from the command line.

you could write a function like this:

function gvim () {
    nohup gvim "$@" > /dev/null 2>&1 & disown
}

(add this function to your .bashrc or .bash_aliases file so it is always loaded)

Explanation:

• this will alias the gvim command with a bash function also named gvim (so when you type gvim at a bash prompt, it will call your gvim function, rather than executing the real gvim command. Your function then calls the real gvim command (and accepts its regular args), with some added features:

  • redirects stdout and stderr to /dev/null (suppresses output to the terminal)
  • uses & to run the command in the background (so your shell isn't blocked)
  • uses disown to remove the background job from the shell (so it won't appear in the list of active jobs)
  • uses nohup to detach the process from the terminal (so you can end your shell session or close your terminal without killing the process)

try adding --help as a command switch and look for "quiet" this should suppress the output , or just launch from GUI. and launch with the switch or find a way to suppress it via script

personally i launch from cli to get that output so im not sure its possible for all GUI apps.
