- 2. Table of Content • Introduction • Features of Linux OS • Basic Linux Commands • Linux Distributions
- 3. Introduction to LINUX • LINUX is an operating system. • LINUX is FOSS(Freeware and Open Source Software). • It was developed by Linus Torvalds and first released on September 17, 1991. • It was developed by using UNIX Kernel. • Linux is an interface between computer/server hardware, and the programs that runs on it.
- 4. Features of Linux OS Free Operating System Linux is a free OS. The operating system is cost-free so you can view, modify, and customize the code without any cost. It facilitates the users by providing: • Free to use this OS for personal use, on the server, and for educational use. Open-source operating System The code of the core component and other software are open to all the users. The facilities the feature includes are: • Anyone can go through the code so one can understand how the kernel works. • Modification is possible according to the user’s preference. One can distribute the modified version to other Linux distributions. Portability • Portability allows it to be used on a wide range of hardware architectures.
- 5. Lightweight This operating system is so lightweight that it can be installed on any small hardware and it uses quite small disk space while installation. Again, other operating systems have many default apps and graphical interfaces but Linux is only a kernel that can be customized. Multiuser and Multitask support It allows numerous users to work on various tasks at once. There are two approaches to this: •Single users doing multiple tasks. •Multiple users do multiple tasks which includes editing file, and using browsing facility at the same time. Security The Linux operating system provides strong security through end-to-end encryption. This encryption feature includes: •All the files are stored with a secure key. •Users have to authenticate it by password.
- 6. Graphical User Interface Linux supports the GUI just like Windows. You can install the packages on the command line or from the server. Well Structure File System Linux has a hierarchical file system in which all files are sorted according to their type and located in a particular directory. There are various types of directories in Linux, such as Binary Directory (bin), Unix System Resource (usr), Configuration Directory (conf), Data Directory, and Memory Directory. Accessible Update The Linux operating system keeps the user’s system up to date by informing them of new updates and making accessible the new versions. Users can upgrade the system based on their requirements.
- 7. Basic Linux Commands • The ls command The ls command is used to list files and directories in the current working directory. • The pwd command The pwd command allows us to print the current working directory on our terminal.
- 8. • The cd command Linux command to navigate through directories • The mkdir command It is used to create directories in Linux
- 9. • The cp and mv commands The cp and mv commands are equivalent to the copy-paste and cut-paste in Windows. But since Linux doesn’t really have a command for renaming files, we also make use of the mv command to rename files and folders.
- 10. • The rm command Delete files or directories. To delete a directory, you have to add the -r argument to it. Without the -r argument, rm command won’t delete directories. • The touch command Create blank/empty files
- 11. • The cat and echo command When you want to output the contents of a file, or print anything to the terminal output, we make use of the cat or echo commands. As you can see in the above example, the cat command when used on our “New-File”, prints the contents of the file. At the same time, when we use echo command, it simply prints whatever follows after the command.
- 12. Linux Distributions There are over 600 Linux distributions, over 300 of which are in active development.
