23 fuser lists all PIDs (Process IDs) that currently have a given
24 file open. fuser can also list all PIDs that have a given network
25 (TCP or UDP) port open.
31 The command kill sends the specified signal to the specified
32 process or process group. If no signal is specified, the TERM
40 killall sends a signal to all processes running any of the
41 specified commands. If no signal name is specified, SIGTERM is
53 Look for processes by name.
59 Pidof finds the process id's (pids) of the named programs. It prints
60 those id's on the standard output.
62 config FEATURE_PIDOF_SINGLE
63 bool "Enable argument for single shot (-s)"
67 Support argument '-s' for returning only the first pid found.
69 config FEATURE_PIDOF_OMIT
70 bool "Enable argument for omitting pids (-o)"
74 Support argument '-o' for omitting the given pids in output.
75 The special pid %PPID can be used to name the parent process
76 of the pidof, in other words the calling shell or shell script.
82 Send signals to processes by name.
88 ps gives a snapshot of the current processes.
90 config FEATURE_PS_WIDE
91 bool "Enable wide output option (-w)"
95 Support argument 'w' for wide output.
96 If given once, 132 chars are printed, and if given more
97 than once, the length is unlimited.
