If you are a Linux system administrator, then monitoring the server load is necessary to maintain stable performance. The server load is an average of the amount of computational work that a computer system performs. It can be defined as an average load over a specific interval of time. If your server load is higher, it will become very slow, sometimes resulting in a shutdown.

In simple terms, the server load refers to the incoming traffic, login requests, hits, and whether the server is available for all users. There are many tools available in Linux for monitoring server load. Monitoring the server load through the command line can save your time and gives you an accurate value of the server load.

In this post, we will show you how to check server load in Linux.

For example, if you want to find the difference between two source code files to develop patches, then you need a file comparison tool to make this process easier. There are several command-line tools available in Linux to compare two files. Among them, diff is a very popular command-line utility that provides various options to get the difference between two files.

In this post, we will show you how to compare two files in a Linux terminal.

The $PATH variable plays an important role in Linux and Unix-based operating systems. It contains a list of directories that hold various executables on the system. The $PATH variable allows you to run any programs in Linux seamlessly. Generally, the $PATH variable contains the /bin, /usr/bin, /usr/local/bin, /sbin and /usr/sbin directories. However, you can also add your own directories to the $PATH variable to execute any script from anywhere on the system without specifying the script’s absolute path.

In this post, we will show you how to set a $PATH variable in Linux.
