What command is used to view the content of a text file in Linux?

The command used to view the content of a text file in Linux is "cat." This command stands for "concatenate" and is primarily used to display the contents of files in the terminal. When you use "cat" followed by the filename, it outputs the entire content of the file to the standard output (usually the terminal window). This makes it a straightforward and quick way to view small text files.

In contrast, while "more" can also be used to view the content of a text file, it operates differently by allowing users to paginate through the content, which can be useful for larger files that don't fit in the terminal window at once. The "ls" command is intended for listing directory contents, which is not related to file content display, while "echo" is used to print a specific string or variable value to the terminal, not for viewing file contents. Thus, "cat" is the most direct and common choice for viewing text files.
