Section: User Commands (1)
Updated: February 17, 1998
Index NAME
killall - kill processes by name
SYNOPSIS
killall[
-eiqvw][
-signal]
name ...killall-l
killall-V
DESCRIPTION
killallsends a signal to all processes running any of the specified commands. If nosignal name is specified, SIGTERM is sent.
Signals can be specified either by name (e.g. -HUP) or by number(e.g. -1). Signal 0 (check if a process exists) can only be specifiedby number.
If the command name contains a slash (/), processes executing thatparticular file will be selected for killing, independent of their name.
killall returns a non-zero return code if no process has been killedfor any of the listed commands. If at least one process has been killed foreach command, killall returns zero.
A killall process never kills itself (but may kill other killallprocesses).
OPTIONS
- -e
- Require an exact match for very long names. If a command name is longerthan 15 characters, the full name may be unavailable (i.e. it is swappedout). In this case, killall will kill everything that matches withinthe first 15 characters. With -e, such entries are skipped.killall prints a message for each skipped entry if -v is specified in addition to -e,
- -i
- Interactively ask for confirmation before killing.
- -l
- List all known signal names.
- -q
- Do not complain of no processes were killed.
- -v
- Report if the signal was successfully sent.
- -V
- Display version information.
- -w
- Wait for all killed processes to die. killall checks once per second ifany of the killed processes still exist and only returns if none are left.Note that killall may wait forever if the signal was ignored, had noeffect, or if the process stays in zombie state.
FILES
/proc location of the proc file system
KNOWN BUGS
Killing by file only works for executables that are kept open duringexecution, i.e. impure executables can't be killed this way.
Be warned that typing killall name may not have the desiredeffect on non-Linux systems, especially when done by a privilegeduser.
killall -w doesn't detect if a process disappears and is replaced bya new process with the same PID between scans.
