 .SH DESCRIPTION
 .B Pidof
 finds the process id's (pids) of the named programs. It prints those
 id's on the standard output.
 .SH OPTIONS
-.IP \-s
+.IP \fB\-s\fP
 Single shot - this instructs the program to only return one \fIpid\fP.
-.IP \-c
+.IP \fB\-c\fP
 Only return process ids that are running with the same root directory.
 This option is ignored for non-root users, as they will be unable to check
 the current root directory of processes they do not own.
-.IP \-q
+.IP \fB\-q\fP
 Quiet mode, suppress any output and only sets the exit status accordingly.
-.IP \-w
+.IP \fB\-w\fP
 Show also processes that do not have visible command line (e.g. kernel
 worker threads).
-.IP \-x
+.IP \fB\-x\fP
 Scripts too - this causes the program to also return process id's of
 shells running the named scripts.
-.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.
-.IP "-S \fIseparator\fP"
+.IP "\fB-S\fP \fIseparator\fP"
 Use \fIseparator\fP as a separator put between pids. Used only when
 more than one pids are printed for the program.
 The \fB\-d\fR option is an alias for this option for sysvinit
