Which Linux command is utilized to delete or remove a file?

The command used to delete or remove a file in Linux is rm. This command stands for "remove," and it is specifically designed to delete files and directories. When you execute the rm command followed by the filename, it will remove that specified file from the filesystem.

Using rm can also include options to enhance its functionality; for example, using -r allows for the removal of directories and their contents recursively, while -f forces the deletion without asking for confirmation.

The other commands serve different purposes: mv is used to move or rename files, rmdir is specifically for removing empty directories, and ps is a command for displaying information about running processes. Understanding the specific function of each command is crucial for effective command-line usage in Linux environments.
