       killall [-d,--sid] [-c,--context] [-e,--exact] [-g,--pro­
       cess-group] [-i,--interactive] [-q,--quiet] [-s,--signal
       signal] [-v,--verbose] [-w,--wait] [-V,--version] [--]
       name ...
       killall -l
       killall -V,--version


       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 exe­
       cuting 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).


       -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  addi­
              tion 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 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.

       -d     (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 -d.  Must precede other arguments on
              the command line.


       /proc     location of the proc file system


       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.
