If you think you know enough about Linux and you are a pro, then why not create your own Linux distribution? Linux From Scratch LFS is a project that provides you with step-by-step instructions for building your own custom Linux system, entirely from source code.
There are various sub-parts of this project, you can check it out on its website and download the books from there. The real power of Linux lies in the command line and if you want to conquer Linux, you must learn Linux command line and Shell scripting. It covers things from beginners to advanced level.
Download it and keep it with you always. This eBook from The Linux Documentation Project is a good place to begin with Linux command line and get acquainted with Shell scripting. This is a free eBook to download from GNU. As the name suggests, it deals with Bash Shell if I can call that.
This book has over pages and it covers a number of topics around Linux command line in Bash. If you just want to get started with Bash scripting, this could be a good companion for you.
If you think you already know basics of Bash scripting and you want to take your skills to the next level, this is what you need. This pages eBook from The Geek Stuff teaches you the essentials of Linux command lines with easy to follow practical examples. Not the prettiest book here but if you really need to go deeper with your scripts, this old-yet-gold book could be helpful.
This section is dedicated to the SysAdmins, the superheroes for developers. I have listed a few free eBooks here for SysAdmin which will surely help anyone who is already a SysAdmin or aspirs to be one. I must add that you should also focus on essential Linux command lines as it will make your job easier. If you use Debian Linux for your servers, this is your bible. This is an ideal book if you are preparing for LPI certification.
The book deals straightway to the topics essential for sysadmins. So knowledge of Linux command line is a prerequisite in this case. Another free eBook by Paul Cobbaut. The pages long eBook covers networking, disk management, user management, kernel management, library management etc.
The reason locate command is faster is because it searches file through the database opposing to file command which initiates a search through the file system. The database has bits of files that result in an almost instantaneous result. Executing the locate command is straightforward to use and one has to do is pass the name of the file. The netstat is a command-line tool that presents an overview of the network connections.
Beyond that, the command also provides several network interface statistics, multicast memberships, routing tables, and masquerade connections. Although it is standard on UNIX-like systems, many other operating systems also have netstat command. The command will display listening and non-listening sockets. Users can always use the -interface option to view only the interface that is down.
You can even choose to view the statics of all ports. Input the following command display overview of all ports:. The cron command is a software utility that is provided by Unix-like operating systems. The primary job of the utility is to schedule the task at a predefined time. Cron is a compelling and popular command that many uses to schedule task periodically at predetermined time or dates. The time-based job scheduler automates scheduling making it very convenient.
The cron runs in the background and is often referred to as a daemon process. Daemon process is a background process that runs for a long time and answers requests for services. The best feature of cron is that it performs its task without the intervention of a user. Commonly most programmers use cron to accomplish repetitive tasks automatically. To complete this repetitive task is daunting, and hence, coders can schedule processes to run automatically.
Users can even schedule processes such as organizing folders at given time intervals, taking backups at regular intervals, and also checking for updates. The traceroute command tracks the route that a particular packet of information takes to reach to the host. In simple words, the command prints the journey that a packet takes from the source to destination. One of the most common purposes to use traceroute is to track where data is lost in the network. As such, that coders can identify the particular node that is down.
More so, the traceroute command will also display all jumps it makes during the journey. Users can also use the -g gate option to route the packet through the gateway.
Rsync stands for Remote Sync is a very standard command leveraged to synchronize files and directories. The software utility is usual among many Unix-like operating systems. The primary purpose of the utility is to sync files between hosts or machines, both locally and remotely.
Beyond that, Rsync is also used to copy files. Below is a basic example of transferring files between two local machines. In the example, we copy a file dubbed examples. RPM stands for Red Hat Package Manager, which is a tool that permits users to install, verify, manage, and uninstall software packages in Linux and Unix-like operating systems.
However, programmers must remember that the utility only works if the software is developed using the. Users can enter the following argument to see if RPM is installed or not on a package.
Coders have to use the -q option. The ifup command is an essential and straightforward way to bring the network interface up and enable it to transfer and receive data.
In other words, coders use the ifup command to configure network interfaces. Programmers must take note that the command is used with Sudo as it deals with permission privileges. The screen command permits users to initiate multiple shell sessions via a single ssh session.
The best feature of the screen command is that the process can be detached from a session and then join the session again at a later period. It is possible as the process because the screen runs the process that was started even after being detached. Therefore, making it possible to reattach the session at a later time. So one can begin the same place where they left off in the terminal.
The command will initiate a new window within the screen and also give the windows it a name. The declare is a bash shell builtin command which means that it is a part of the shell. It has multiple purposes, such as declare shell functions, display variables, and more. The cpio command is a standard among many Unix-like operating systems with the primary purpose being processing archive files.
In simple words, programmers can use the cpio command to copy files from archives such as. The command will extract files and directory with a single argument. Similarly, coders can even use cpio to extract. The exec command is leveraged to run a command directly from the bash.
Therefore it does create a new process but instead substitutes it with the command that has to be executed. So, if the argument is successful, then it won't come back to the calling process. The exec can be used as an argument or without a command.
Below is an example of the exec:. Awk is a software utility that one can leverage to write small programs in the way of statements. Users can utilize these statements to define text patterns which can be searched in a document.
One of the primary purposes of Awk is to scan patterns and processes. Awk is actually a scripting language that is mostly leveraged by programmers to manipulate data. With Awk, coders do not have to use compiles but can run scripts with logical operators, variables, and string functions. We will shorty upload a linux commands pdf file to download for free. Meantime, you can bookmark this page for all linux commands. The article covers most of the basic Linux commands that one will come across.
There are various other commands, but commonly the above listed 50 Linux commands will do the job. More so, running commands on Linux is all about combining it with the right option. There are multiple ways to get the job done, and one must use logic to choose the best possible option. Top 50 Linux Commands With Examples. Top 50 Linux Commands With Examples Linux is one of the most popular operating systems with an extensive user-base around the world, most commonly programmers and developers.
Alias Command 3. SSH Command Enable Command Cp Command Locate Command There are dozens of reasons behind it. One reason is that Kali comes preloaded with many useful tools used for penetration testing. We should have basic knowledge of Kali Linux commands.
It gives us full portability and power to boot on any machine. Here are all Kali Linux commands with examples. From F From X Keep this in mind that these commands are related to the inbuilt function of OS.
