Question

I want to execute a Linux shell command from “/sbin/” with execl or system (or another command), and hide its output.

I am using “fork” already to get a child process…

Like if I entered…

service "servicename" restart

I would see the output where it says “restarting xyz [OK]”. Instead, I simply want the command to be executed silently and its output discarded instead of being shown in my console application.

Answer 1

Redirect the output to /dev/null

Eg.,

service smb restart 1> /dev/null

service smb restart 2> /dev/null

where 1 and 2 represents the stdout and stderr
