Which command is used to view the contents of a file in Linux?

The command used to view the contents of a file in Linux is often the cat command. This command concatenates and displays the content of files directly in the terminal. It is a straightforward tool that outputs the entire content of a file to the standard output (usually the terminal) without any additional formatting or paging. When you use cat filename, it will show the contents of "filename" all at once, which is useful for small text files or when you want to quickly check the content.

While other commands listed can also be used to view file contents, they have different functionalities or user experiences. For instance, when using the more command, it displays the content one screen at a time, which is particularly useful for larger files, allowing for easier navigation through the content. The view command is essentially a read-only version of the text editor vi, which provides an interface for viewing and navigating files but is more complex compared to cat. The read command does not exist in a way that facilitates file content viewing; instead, it is typically a shell built-in that reads a line from standard input into a variable.

Therefore, cat stands out as the most direct and efficient method for viewing file contents
