How to Kill All Processes in Linux?

• nohup lets you run a program in a way which makes it ignore hangup signals.
• ps displays a list of current processes and their properties.
• kill is used to send termination signals to processes.
• pgrep search and kill system processes.
• pidof display Process ID (PID) of a task.
• killall kill a process by name.

pkill is what I recommend, if it’s available (Linux, FreeBSD, NetBSD, OpenBSD, Solaris). You can specify processes by the command name, by the full command line or other criteria. For example, pkill vi kills all programs whose command name contains the substring vi . To kill only processes called vi , use pkill -x vi .To kill this job/process, either a kill %1 or a kill 1384 works. Remove job(s) from the shell’s table of active jobs. The fg command switches a job running in the background into the foreground. The bg command restarts a suspended job, and runs it in the background.There is one exception: even root cannot send a fatal signal to PID 1 (the init process). However kill -9 is not guaranteed to work immediately. All signals, including SIGKILL, are delivered asynchronously: the kernel may take its time to deliver them.
