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

The command used to remove a file in Linux is "rm filename.txt." The "rm" command stands for "remove," and it is a standard command in Unix-like operating systems, including Linux, for deleting files and directories from the filesystem.

When executed, "rm" will delete the specified file (in this case, filename.txt) without sending it to a trash or recycle bin, so caution is advised when using it. If the file exists and the user has the appropriate permissions, it will be permanently removed from the system.

The other commands listed do not correspond to the standard Linux command for removing files. For example, "del" is a command used in DOS and Windows environments, while "erase" and "remove" are not standard commands in Linux for file deletion. Understanding these nuances is essential for effective navigation and file management within a Linux environment.
