Which command would you use to remove a file in Linux?

The command used to remove a file in Linux is 'rm'. This command is widely recognized and utilized in Unix-like operating systems, including various Linux distributions. When invoked, 'rm' deletes files from the filesystem. It can also be combined with different options and flags to enhance its functionality, such as '-r' for recursive removal of directories and their contents, or '-i' to prompt the user for confirmation before deletion.

Understanding that 'rm' is a fundamental command in Linux for managing files is critical for effectively navigating the system and performing operations related to file management. The other options listed do not represent valid commands in the context of Linux, as they are either associated with other operating systems or simply do not exist in the Linux command set.
