Knowing when and how to stop running processes is a essential skill for sysadmins. When a process becomes stuck, it only takes a gentle nudge to restart or stop it.

At times, a process takes all the system resources. In both cases, you need a cmd that lets you manage a process.
The Linux operating system includes a number of commands for terminating errant processes (rogue processes), such as pkill, kill, and killall.

This thread will teach you how to use the kill command in Linux.

As a sysadmin or Linux power user, how do you transfer files from your local system to a remote?

To synchronize directories or files to another machine we need a fast and reliable tool. In this thread, we will learn about the rsync command in Linux using some practical examples.
rsync is a command-line utility that can synchronize files and directories between two locations via a remote shell or from/to a remote Rsync daemon.

It enables rapid incremental file transfer by transferring only the differences between the source and destination files.
Rsync can be used to mirror data, perform incremental backups, copy files between systems, and to replace the scp, sftp, and cp commands.
