## Name

KILL — Abort a process

## Synopsis

`kill` `procID`

## Description

This shell “built in” command sends an “abort” signal to the process having the process ID number specified. The process to be aborted must have the same user ID as the user that executed the command. The procs command can be used to obtain the process ID numbers.

NOTE: If a process is waiting for I/O, it may not die until it completes the current I/O operation, therefore, if you kill a process and the procs command shows it still exists, it is probably waiting for receive a line of data from a terminal before it can die. Since this is a built-in shell command, it does not appear in the CMDS directory. For more information see: the section called “Built-in Shell Commands and Options”, the section called “Process States”, procs
