Prompt may refer to:

• Command prompt, in computing, one or more characters in a command line interface to indicate that the computer is ready to accept typed input
• Prompt (theatre) or "prompter", in theatre, the person who prompts an actor when they forget their next line
• Prompt corner or prompt box, the location at the side of the stage where the prompt is located
• Prompt critical, in nuclear engineering, the state of an assembly when for each nuclear fission event, one or more of the immediate or prompt neutrons released causes an additional fission event
• Prompt neutron, in nuclear engineering, a neutron immediately emitted by a nuclear fission event, as opposed to a delayed neutron
• PROMPT Telescopes, an array of telescopes located at CTIO which are designed to rapidly observe gamma-ray burst afterglows simultaneously in multiple filters

PROMPT, an acronym for Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes, is currently being built by the University of North Carolina at Chapel Hill at Cerro Tololo Inter-American Observatory (CTIO) in Chile. PROMPT's primary objective is rapid and simultaneous multiwavelength observations of gamma-ray burst afterglows, some when they are only tens of seconds old. In addition to measuring redshifts by dropout, and early-time SFDs and extinction curves of sufficiently bright afterglows in unprecedented detail, PROMPT will facilitate quick response observations at larger observatories such as the UNC-led 4.1-m SOAR Telescope. PROMPT will also serve as a platform for undergraduate and high school education throughout the State of North Carolina.

Eingabeaufforderung (auch Prompt, engl. ‚abfragen, auffordern‘) ist ein Begriff aus dem IT-Bereich und bezeichnet eine Markierung auf der Kommandozeile (Eingabekonsole), welche auf die Stelle verweist, an der man Kommandozeilenbefehle eingeben kann. Dieser Prompt wird typischerweise durch den Kommandozeileninterpreter ausgegeben.

Le mot prompt peut être employé comme :

• adjectif, il est synonyme de rapide
• nom commun (anglicisme), il désigne l'invite de commande (caractère indiquant que l'ordinateur est prêt à recevoir une saisie au clavier).
• nom propre, il désigne une marque de logiciel de traduction automatique.

Kommandotolk är ett typ av skalprogram, är ett gränssnitt där en dators användare kan skriva in kommandon. Det program som används som kommandotolk kan oftast även användas för att köra enkla program, så kallade skript.

Interfaccia a linea di comando (dall'inglese Command Line Interface, in acronimo CLI) è un termine generico per descrivere un programma che permette all'utente di interagire scrivendo righe di comando su un terminale testuale. L'esempio tipico sono le shell, ma anche altri programmi utilizzano questo approccio.
