# parkill(1)

Kill all processes running a specified command

## NAME

parkill - Kill all processes running a specified command

## SYNOPSIS

**parkill \[ -debug \] \[ -verbose \] \[ -user=name \] program**

## DESCRIPTION

**parkill** kills all processes running a specified command.

Many systems also have the "killall" command; this should be used instead if it is available.

This script relies on the ps command; where possible, it uses the /proc/\<pid\>/cmdline interface to more reliably access the commandline (to avoid matching command line parameters as if they were functions).

## OPTIONS

- **-debug**

  Print debug information.

- **-verbose**

  Be verbose.

- **--user=name**

  Only kill processes belonging to a particular user. Root privileges are required for this option.
