AWK je interpretirani programski jezik dizajniran za obradu teksta i najčešće korišćen kao alatka za izvoženje podataka i izveštaje. Jedan je od standardnih alata na Juniks-baziranim operativnim sistemima.
Razvijen je u Bell Laboratories istraživačkom centru 1970[1], a ime je dobio po prezimenima njegovih autora. Akronim se izgovara identično imenu ptice auk (njorke, koja predstavlja amblem jezika i pojavljuje se u literaturi). Kada se piše malim slovima, misli se na program iz juniksa i Plan 9 operativnog sistema koji pokreće skripte pisane u AWK programskom jeziku.
Primeri aplikacija
Zdravo svete
Evo uobičajenog 'Zdravo svete' programa napisanog u AWK:
BEGIN { print "Hello, world!" }
Imajte na unu da eksplicitna exit izjava nije potrebna; pošto je jedini obrazac BEGIN, argumenti komandne linije se ne obrađuju.
