KILLALL(1)                       User Commands                      KILLALL(1)



 

NAME


       killall - kill processes by name

 

SYNOPSIS


       killall [-Z,--context pattern] [-e,--exact] [-g,--process-group]
       [-i,--interactive] [-q,--quiet] [-r,--regexp] [-s,--signal signal]
       [-u,--user user] [-v,--verbose] [-w,--wait] [-I,--ignore-case]
       [-V,--version] [--] 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 -SIGHUP ) or by
       number (e.g. -1) or by option -s.

       If the command name is not regular expression (option -r) and  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 listed command, or no commands were listed and at least
       one process matched the -u and -Z search criteria. killall returns non-
       zero otherwise.

       A  killall  process never kills itself (but may kill other killall pro-
       cesses).

 

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 every-
              thing 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,

       -I, --ignore-case
              Do case insensitive process name match.

       -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
              belonging 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.

       -r, --regexp
              Interpret  process  name  pattern as an extended regular expres-
              sion.

       -s, --signal
              Send this signal instead of SIGTERM.

       -u, --user
              Kill only processes the specified user owns. Command  names  are
              optional.

       -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.

       -Z, --context
              (SELinux  Only)  Specify  security  context: kill only processes
              having security context that match with given  expended  regular
              expression  pattern. Must precede other arguments on the command
              line. Command names are optional.

 

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.

       If  processes  change their name, killall may not be able to match them
       correctly.
