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,--context] [-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 par-
    ticular 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 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,

    -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.

    -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  argu-
    ments on command line.

    -c   (Flask only) Specify security context: kill only processes with
    given security context. Mutually exclusive with -s. Must pre-
    cede 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.
