The command used to delete a file in Linux is the 'rm' command. This command stands for "remove" and is specifically designed to remove files and directories from the filesystem. When you issue 'rm filename', it immediately deletes the specified file without moving it to a recycle bin or trash, which is common in other operating systems.

The 'rm' command is versatile, allowing for the deletion of multiple files at once or directories when used with the '-r' option. Its straightforward syntax and power make it a fundamental tool for file management in Linux.

Other options mentioned are not valid commands in Linux. For example, 'del' is a command used in DOS and Windows environments for deleting files but does not exist in the Linux command set. Likewise, 'delfile' and 'erase' are not recognized commands in Linux for file deletion, further emphasizing 'rm' as the correct choice for this operation.
