.SH SYNOPSIS
.B killall5
.RB -signalnumber
+.RB [ \-o
+.IR omitpid ]
+.RB [ \-o
+.IR omitpid.. ]
.SH DESCRIPTION
.B killall5
is the SystemV killall command. It sends a signal to all processes except
kernel threads and the processes in its own session, so it won't kill
the shell that is running the script it was called from. Its primary
(only) use is in the \fBrc\fP scripts found in the /etc/init.d directory.
+.SH OPTIONS
+.IP "-o \fIomitpid\fP"
+Tells \fIkillall5\fP to omit processes with that process id.
+.SH NOTES
+\fIkillall5\fP can also be invoked as pidof, which is simply a
+(symbolic) link to the \fIkillall5\fP program.
+.SH EXIT STATUS
+The program return zero if it killed processes. It return 2 if no
+process were killed, and 1 if it was unable to find any processes
+(/proc/ is missing).

.IP -x
Scripts too - this causes the program to also return process id's of
shells running the named scripts.
-.IP -o \fIomitpid\fP
+.IP "-o \fIomitpid\fP"
Tells \fIpidof\fP to omit processes with that process id. The special
pid \fB%PPID\fP can be used to name the parent process of the \fIpidof\fP
program, in other words the calling shell or shell script.
+.SH "EXIT STATUS"
+.TP
+.B 0
+At least one program was found with the requested name.
+.TP
+.B 1
+No program was found with the requested name.
.SH NOTES
-\fIpidof\fP is simply a (symbolic) link to the \fIkillall5\fP program,
-which should also be located in \fP/sbin\fP.
+\fIpidof\fP is actually the same program as \fIkillall5\fP;
+the program behaves according to the name under which it is called.
.PP
When \fIpidof\fP is invoked with a full pathname to the program it
should find the pid of, it is reasonably safe. Otherwise it is possible
