What is the primary function of the 'sort' command in Linux?

• A. Change the permissions of a file or directory
• B. Send ICMP ECHO_REQUEST to test connectivity
• C. Sort the contents of a file or STDIN
• D. View detailed information about a file

Answer: (C)

The primary function of the 'sort' command in Linux is to sort the contents of a file or standard input (STDIN). When this command is executed, it reads lines from the input and arranges them in a specified order, typically in ascending order. Users can define various sorting criteria, such as numerical or lexicographical order, and the command can be combined with other commands or options to filter and modify the output further. This functionality is particularly useful for organizing data, such as lists or logs, and makes it easier to analyze or read information in a structured manner. For example, if you have a file containing unsorted names, using the 'sort' command would provide a neatly ordered list, enhancing data readability and accessibility. The command demonstrates a fundamental aspect of Linux's design, allowing users to manipulate data efficiently through command line tools. In contrast, options referencing changing permissions, testing connectivity, or viewing file information involve different commands and functionalities that serve distinct purposes within the Linux operating system.
