KILLALL(1) User Commands KILLALL(1) NAME
killall - kill processes by name SYNOPSIS
killall [-e,--exact] [-g,--process-group] [-i,--interactive] [-q,--quiet] [-v,--verbose] [-w,--wait] [-V,--version] [-S,--sid] [-c,--con- text] [-s,--signal signal] [--] name ... killall -l killall -V,--version DESCRIPTION
killall sends a signal to all processes running any of the specified commands. If no signal name is specified, SIGTERM is sent. Signals can be specified either by name (e.g. -HUP) or by number (e.g. -1). If the command name contains a slash (/), processes executing that particular file will be selected for killing, independent of their name. killall returns a zero return code if at least one process has been killed for each ilisted command. killall returns zero otherwise. A killall process never kills itself (but may kill other killall processes). OPTIONS
-e, --exact Require an exact match for very long names. If a command name is longer than 15 characters, the full name may be unavailable (i.e. it is swapped out). In this case, killall will kill everything that matches within the 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, -g, --process-group Kill the process group to which the process belongs. The kill signal is only sent once per group, even if multiple processes belong- ing to the same process group were found. -i, --interactive Interactively ask for confirmation before killing. -l, --list List all known signal names. -q, --quiet Do not complain if no processes were killed. -v, --verbose Report if the signal was successfully sent. -V, --version Display version information. -w, --wait Wait for all killed processes to die. killall checks once per second if any 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 no effect, or if the process stays in zombie state. -S (Flask only) Specify SID: kill only processes with given SID. Mutually exclusive with -c argument. Must precede other arguments on command line. -c (Flask only) Specify security context: kill only processes with given security context. Mutually exclusive with -s. Must precede other arguments on the command line. FILES
/proc location of the proc file system KNOWN BUGS
Killing by file only works for executables that are kept open during execution, i.e. impure executables can't be killed this way. Be warned that typing killall name may not have the desired effect on non-Linux systems, especially when done by a privileged user. killall -w doesn't detect if a process disappears and is replaced by a new process with the same PID between scans.
