Short separator option used 's' instead of 'S' which
meant it pidof would use the single-shot option when you
meant separator.
Added alias for -S using -d to give some sysvinit pidof
compatibility.

.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
|
|
Single shot - this instructs the program to only return one \fIpid\fP.
|
|
.IP \-c
|
|
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 \-x
|
|
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"
|
|
Use \fIseparator\fP as a separator put between pids. Used only when
|
|
more than one pids are printed for the program.
|
|
The \fI\-d\fR option is an alias for this option for sysvinit pidof
|
|
compatibility.
|
|
.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 BUGS
|
|
When using the \fI\-x\fP option,
|
|
.B pidof
|
|
only has a simple method for detecting scripts and will miss scripts that,
|
|
for example, use env. This limitation is due to how the scripts look in
|
|
the proc filesystem.
