What is the command to remove a file in Linux?

• A. mkdir
• B. rm
• C. cat
• D. rmdir

Answer: (B)

The command to remove a file in Linux is "rm." This command is specifically designed for deleting files and works by taking the filename as an argument. When you execute "rm filename," the specified file will be permanently removed from the file system without moving it to any trash or recycle bin; thus, it is essential to use this command carefully.

The other commands listed serve different purposes. "mkdir" is used to create new directories rather than remove files. "cat" is a command primarily used for concatenating and displaying file contents, not for removal. "rmdir," on the other hand, is intended for removing empty directories. While it shares a similar function with "rm," it is not applicable for deleting files that may contain data. Understanding these distinctions is crucial for effective file management in a Linux environment.
