cat (Unix)

Uit Wikipedia, de vrije encyclopedie

Het cat-commando, wat staat voor concatenate, is een standaardprogramma[1] voor Unix-achtige systemen om een of meer bestanden en/of de standaardinvoer samen te voegen en af te drukken op de standaarduitvoer. Vaak wordt het in combinatie met een zogenaamde pipe gebruikt om de inhoud van een reeks bestanden te verwerken:

cat bestand1 bestand2 bestand3 | een_commando met eventueel argumenten

Op GNU-systemen is cat onderdeel van het pakket GNU Core Utilities.
