Linux Tutorials
On the Linux command line, you work with several types of files, for example, directories, symbolic links, and stuff like that. Sometimes, the requirement is to know more about individual elements in a path – what type of file it is, who is its owner, and more. Thankfully, there’s an inbuilt Linux command line utility – dubbed namei – that lets you fetch this information.
In Linux, if you want to print a file’s content on stdout, the first command that comes to mind is cat. However, there may be times when the requirement is to remove certain part of the file and print only the rest of the content. You’ll be glad to know there exists a tool – dubbed cut – that lets you do this.
Processes form the core of a running Linux system. When a program converts into a process (which is when it’s executed), a lot of attributes are set. Sometimes, you may want to change these attributes at runtime. There exists a command line tool chrt that lets you do this.
While compression is helpful in general as it allows you to save space on your system, command line users need to uncompress the file for several small tasks, like viewing what all the file contains. However, there exists a command line utility – dubbed zcat – that lets you take a peek inside compressed files without any additional effort.
If your work involves running tools and scripts on the Linux command line, I am sure there are a lot of commands you would be running each day. Those new to the command line should know there exists a tool – dubbed history – that gives you a list of commands you’ve executed earlier.
There exists a command – dubbed dmesg – that you can use if you want to access messages printed by kernel. In this tutorial, we will understand how the dmesg tool works using some easy to understand examples.
If you are on a Debian or Debian-based system (like Ubuntu), there are high chances you might have encountered .deb packages. These are Debian packages, and Linux command line offers built-in commands/tools to deal with this kind of packages. One such tool is dpkg, which we will discuss here in this tutorial.
If you are new to Linux command line, and are interested in learning networking stuff, there are many command line utilities that you should be aware of. One such tool is netstat. In this article, we will discuss this command using some easy to understand examples.
As a Linux command line user, you should be aware of utilities that help you with user-account management. Once such tool is passwd, which lets you change your account password. In this tutorial, we will discuss the basics of this command using some easy to understand examples.
Looking inside a binary/executable file to grab human-readable strings isn’t the kind of work that everybody does, but what if you are asked to do this? Opening the file in an editor, and manually looking for stuff isn’t an elegant solution. So, what to do? Yes, you guessed it right – there exists a command line utility that does this for you.
