!!DESCRIPTION |

|

|
| |
|
24 |
__Pidof__ finds the process id's (pids) of the named |
| |
|
25 |
programs. It prints those id's on the standard output. This |
| |
|
26 |
program is on some systems used in run-level change scripts, |
| |
|
27 |
especially when the system has a ''System-V'' like |
| |
|
28 |
''rc'' structure. In that case these scripts are located |
| |
|
29 |
in /etc/rc?.d, where ? is the runlevel. If the system has a |
| |
|
30 |
__start-stop-daemon__ (8) program that should be used |
| |
|
31 |
instead. |

Single shot - this instructs the program to only return one |
| |
|
39 |
''pid''. |

-x |
| |
|
43 |
|
| |
|
44 |
|
| |
|
45 |
Scripts too - this causes the program to also return process |
| |
|
46 |
id's of shells running the named scripts. |
| |
|
47 |
|
| |
|
48 |
|
| |
|
49 |
-o |
| |
|
50 |
|
| |
|
51 |
|
| |
|
52 |
Tells ''pidof'' to omit processes with that process id. |
| |
|
53 |
The special pid __%PPID__ can be used to name the parent |
| |
|
54 |
process of the ''pidof'' program, in other words the |
| |
|
55 |
calling shell or shell script. |

!!NOTES |

|
| |
|

''pidof'' is simply a (symbolic) link to the |
| |
|
60 |
''killall5'' program, which should also be located in |
| |
|
61 |
''/sbin''. |
| |
|
62 |
|
| |
|
63 |
|
| |
|
64 |
When ''pidof'' is invoked with a full pathname to the |
| |
|
65 |
program it should find the pid of, it is reasonably safe. |
| |
|
66 |
Otherwise it is possible that it returns pids of running |
| |
|
67 |
programs that happen to have the same name as the program |
| |
|
68 |
you're after but are actually other programs. |
