The command "atom" is used to launch the Atom text editor. In this specific command, "${filename_or_directory}" is used as a placeholder. It means you should replace it with the actual name of a file or directory that you want to open in Atom. For example, if you have a file named "script.js" and you want to open it in Atom, you would replace "${filename_or_directory}" with "script.js" to give the command: atom script.js Likewise, if you have a directory named "project" and you want to open it in Atom, you would replace "${filename_or_directory}" with "project", resulting in the command: atom project By using this command, you can easily open files or directories in Atom from the command line.
