Kill command in UNIX and Linux is normally used to kill a suspended or hanged process or process group. Though kill is mainly associated with kill operation its mere a signal transporter and can send specified signal to specified process in UNIX or UNIX like systems e.g. Linux, Solaris or FreeBSD. Like in windows when we see a particular process hung the system we go to task-manager find the process and kill it, similarly in UNIX and Linux we first find the process ID (PID) of offending process and then kill it. Though we have killAll command also which doesn't require PID instead it can kill the process with just process name. Kill commands is often a wrapper around kill () system call but some Linux systems also has built-in kill in place. In this article we will see some examples of kill command in UNIX and how we can use kill command to kill the locked process.
