What command would you use to remove a linked file?

The command used to remove a linked file is best answered by the command "unlink." This command specifically targets single files (including hard links) and is designed for the purpose of removing links from the file system. When you use unlink on a linked file, it effectively removes the link, and if it is the last link to that file, the data is removed from the file system itself.

While the command "rm" can also be used to remove linked files by specifying the name of the file, it is a more general-purpose command that is actively used to remove directories and multiple files as well. It can be used in a wide variety of ways, including recursive removals, making it more complex than necessary for the simple task of unlinking a single file.

The other options, "delete" and "remove," are not valid command-line utilities in Linux for removing files and do not correspond to any recognized command for this action. Therefore, the best and most specific command for removing a linked file is "unlink."
