Overview of this book

Linux is one of the most sought-after skills in the IT industry, with jobs involving Linux being increasingly in demand. Linux is by far the most popular operating system deployed in both public and private clouds; it is the processing power behind the majority of IoT and embedded devices. Do you use a mobile device that runs on Android? Even Android is a Linux distribution. This Linux book is a practical guide that lets you explore the power of the Linux command-line interface. Starting with the history of Linux, you'll quickly progress to the Linux filesystem hierarchy and learn a variety of basic Linux commands. You'll then understand how to make use of the extensive Linux documentation and help tools. The book shows you how to manage users and groups and takes you through the process of installing and managing software on Linux systems. As you advance, you'll discover how you can interact with Linux processes and troubleshoot network problems before learning the art of writing bash scripts and automating administrative tasks with Cron jobs. In addition to this, you'll get to create your own Linux commands and analyze various disk management techniques. By the end of this book, you'll have gained the Linux skills required to become an efficient Linux system administrator and be able to manage and work productively on Linux systems.

Moving one file

Sometimes, you may want to move a file (or a directory) to a different location instead of copying and wasting disk space.

To do this, you can use the mv command. For example, you can move the file copycats.txt from Elliot's home directory to /tmp by running the mv copycats.txt /tmp command:

elliot@ubuntu-linux:~$ mv copycats.txt /tmp
elliot@ubuntu-linux:~$ ls
apple.txt carrot.txt cities d2 Desktop Downloads
banana.txt cats.txt d1 d3 dir1 Pictures
elliot@ubuntu-linux:~$ cd /tmp
elliot@ubuntu-linux:/tmp$ ls
apple.txt carrot.txt cats.txt copycats.txt d2
banana.txt cats2.txt cities d1 d3

Notice that copycats.txt is now gone from Elliot's home directory as it relocated to /tmp.
