Scripting language
Scripting redirects here. For other uses, see
script. Scripting languages (commonly called script languages) are computer
programming languages that are typically
interpreted and can be typed directly from a keyboard. Thus, scripts are often distinguished from programs, because programs are converted permanently into
binary executable files (i.e. machine code) before they are run (There are some interpreters which convert the script into some suitable binary form, for efficiency reasons, but this is transparent to the user). Scripts remain in their original form and are interpreted command-by-command each time they are run. Scripts were created to shorten the traditional edit-
compile-
link-run process. The name 'script' is derived from the written script of the
performing arts, in which dialogue is set down to be interpreted by actors and actresses--the programs. Early script languages were often called batch languages or job control languages. Scripting languages can also be compiled, but because interpreters are simpler to write than compilers, they are interpreted more often than they are compiled.

Skriptsprache
Skriptsprachen (häufig auch Scriptsprachen) sind
Programmiersprachen, die vor allem für kleine, überschaubare Programmieraufgaben gedacht sind. Sie verzichten oft auf bestimmte Sprachelemente, deren Nutzen erst bei der Bearbeitung größerer Projekte zum Tragen kommen. So wird etwa in Skriptsprachen auf den
Deklarationszwang von Variablen verzichtet – vorteilhaft zur schnellen Erstellung von kleinen Programmen (siehe auch
Prototyping (Softwareentwicklung)), bei großen hingegen von Nachteil, etwa wegen der fehlenden Überprüfungsmöglichkeit von
Tippfehlern in Variablennamen.

Scripting
Descrizione delle azioni richieste mediante opportuni
linguaggi di programmazione, detti appunto linguaggi di scripting.Il programma, detto script, definisce il controllo delle operazioni richieste al calcolatore. Spesso progettati per l'uso interattivo, e con molti comandi eseguibili individualmente di complessità anche elevata (ad esempio nella
shell Unix sh la maggior parte delle operazioni sono programmi essi stessi). Gli script vengono spesso usati per compiti a singola passata, tipicamente di tipo amministrativo o di utilità. Il codice degli script è tipicamente contenuto in file di testo e vengono interpretati. In alcuni casi (come il
Perl) vengono compilati ad ogni esecuzione.
