Default Extracting reads with specific barcodes


I've received Illumina PE files, which I've been told contain several samples, and that the barcode I want is GT. From what I've understood, barcodes are a sequence of 2-3 bases added to the beginning of each read so that several small samples can be sequenced in one lane.

Is there a program that can be used to separate the reads with my barcode from the others?
