SYNOPSIS         top

       setsid [options] program [arguments]

DESCRIPTION         top

       setsid runs a program in a new session. The command calls fork(2)

       program in the current process. This default behavior is possible
       to override by the --fork option.

           Set the controlling terminal to the current one.

       -f, --fork
           Always create a new process.

       -w, --wait
           Wait for the execution of the program to end, and return the
           exit status of this program as the exit status of setsid.

       -V, --version
           Display version information and exit.
