Checking disk space in Linux is a fundamental task for system administrators and users alike. It helps to ensure that there is sufficient storage capacity for the operating system, applications, and user data. There are several commands that can be used to check disk space in Linux, each with its own advantages and use cases.
One of the most common commands for checking disk space is df. Df stands for “disk free” and it provides a summary of the available and used space on all mounted file systems. To use df, simply type “df” in a terminal window. The output will show the total space, used space, available space, and percentage of used space for each mounted file system.
