I am sure you would have come across Windows' processes that hang. And I am sure you know what to do. CTL + ALT + DEL and kill the process using the Task Manager. In this article, we'll how to do that on Unix using command line.
Here are the steps:
1) See the PID of the process that has hung and you want to kill. Execute the following command in the terminal.
ps aux
This command will list all the processes running on your system. Here is the format:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 29364 2864 ? Ss Sep15 0:01 /sbin/init root 2 0.0 0.0 0 0 ? S Sep15 0:00 [kthreadd] root 3 0.0 0.0 0 0 ? S Sep15 0:00 [ksoftirqd/0] root 5 0.0 0.0 0 0 ? S< Sep15 0:00 [kworker/0:0H] root 7 0.0 0.0 0 0 ? S Sep15 0:00 [rcu_sched] root 8 0.0 0.0 0 0 ? S Sep15 0:00 [rcuos/0] root 9 0.0 0.0 0 0 ? S Sep15 0:00 [rcuos/1] root 10 0.0 0.0 0 0 ? S Sep15 0:00 [rcu_bh] root 1026 0.0 0.1 248388 11928 ? Ssl Sep15 0:00 /usr/sbin/glusterd -p /var/run/glusterd.pid root 1038 0.0 0.0 19188 764 ? Ss Sep15 0:10 /usr/sbin/irqbalance syslog 1075 0.0 0.0 255844 1416 ? Ssl Sep15 0:00 rsyslogd root 1084 0.0 0.0 4368 664 ? Ss Sep15 0:00 acpid -c /etc/acpi/events -s /var/run/acpid.socket
2) Note down the PID of the process I want to stop. As an example, let's assume that I want to stop the process /usr/sbin/glusterd. Its PID is 1026.
3) Execute the following command on the command line.
sudo kill 1026
Execute ps aux command again and make sure that your unresponsive program has been killed. If it's still present, execute the following on the command line.
sudo kill -9 1026
Now that should do it! :)
