That description doesn&#x27;t do it justice. You didn&#x27;t have to open an executable from the Finder; you could call it from the command line, as in<p><pre><code>  &gt;commando ls
</code></pre>
That popped up a dialog box with checkboxes for -l, -R, etc., with a text field for file names, a button that allowed you to pick files, etc.<p>There were two ways to exit the dialog. One executed the command, the other entered it in your shell for further editing, copy-pasting in a script (in MPW shell, that copy-pasting wasn&#x27;t even needed, as every shell window was a file), etc.<p>And even better: the shell (at least in MPW) knew about commando, so typing<p><pre><code>  &gt;ls…
</code></pre>
or just typing <i>ls</i> and hitting command-option-return (or some other magic incantation) opened the dialog, too.<p>I may misremembered it, but IIRC, commando even parsed partial inputs to populate the dialog box when you opened it.<p>Thinking of MPW and the early Mac, I also miss the consistent distinction between return (the key to the right of the letter &#x27;l&#x27; that starts a new line) and command-return or enter (on the numeric keypad, starts a command) that made it possible to enter multi-line text in input dialogs without living in the constant fear of dismissing the dialog early.
