Testing the forking process.
Hey, first time poster and a new UNIX user here.

My question is regarding the forking process. I logged in to tty1, and typed the command ls -1 and hit enter. How can i tell that the ls -1 command ran in a subshell?


Thanks.

LEARN ABOUT NETBSD

rwho

RWHO(1) 						    BSD General Commands Manual 						   RWHO(1)

NAME

     rwho -- who is logged in on local machines

SYNOPSIS

     rwho [-aHq]

DESCRIPTION

     The rwho command produces output similar to who(1), but for all machines on the local network.  If no report has been received from a machine
     for 11 minutes then rwho assumes the machine is down, and does not report the users last known to be logged into that machine.

     If a user hasn't typed to the system for a minute or more, then rwho reports this idle time.

     -a 	 Include all users.  By default, if a user hasn't typed to the system for an hour or more, then the user will be omitted from the
		 output.

     -H 	 Write column headings above the regular output.

     -q 	 ``Quick mode'': List only the names and the number of users currently logged on.  When this option is used, all other options are
		 ignored.

FILES

     /var/rwho/whod.*  information about other machines

SEE ALSO

     finger(1), rup(1), ruptime(1), rusers(1), who(1), rwhod(8)

HISTORY

     The rwho command appeared in 4.3BSD.

BUGS

     This is unwieldy when the number of machines on the local net is large.
