4 years ago Depends on how pedantic we need to be with this. There are overlapping channel numbers in 5GHz and 2.4GHz bands. There are also overlapping channels if dealing with 60GHz. If concerned about these scenarios we would need the user to supply yet another option in the form of the band as well. If not concerned then we can just loosely take 1-14 and the other channels that airodump-ng uses {36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 100, 102, 104, 106, 108, 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 132, 134, 136, 138, 140, 142, 144, 149, 151, 153, 155, 157, 159, 161, 165, 169, 173}. The idea of just having --freq is that the onus is passed to the user in those overlapping cases.
If you still prefer the later than a patch like the following would suffice I assume:
