I have a bash script that runs a program with parameters. That program outputs some status (doing this, doing that...). There is no option for this program to be quiet. How can I prevent the script from displaying anything?
I am looking for something like windows "echo off".
The following sends standard output to the null device (bit bucket).
and if you also want error messages to be sent there, use one of (the first may not work in all shells):
scriptname &>/dev/null scriptname >/dev/null 2>&1 scriptname >/dev/null 2>/dev/null
and, if you want to record the messages but not see them, replace
/dev/null with an actual file, such as:
For completeness, under Windows cmd.exe (where "nul" is the equivalent of "/dev/null"), it is :
scriptname >nul 2>nul
script > /dev/null 2>&1
This will prevent standard output and error output, redirecting them both to
