What command is used to remove a file in Linux?

The command used to remove a file in Linux is "rm." This command stands for "remove" and is specifically designed for deleting files and directories from the file system. It is a standard Unix command that has been adopted in Linux, and it provides a straightforward way to manage files through the terminal.

When using "rm," you can specify various options to modify its behavior, such as using "-r" to remove directories recursively or "-f" to force removal without prompts. This flexibility makes "rm" a powerful tool in the command-line environment for file management.

The other options, although they might sound plausible, are not commands in the Linux operating system for removing files. For example, "del" is commonly used in Windows systems for deleting files, while "remove" and "erase" are not recognized as valid commands in Linux environments. Therefore, understanding that "rm" is the correct and standard command for file deletion in Linux is crucial for effective command-line usage.
