szap-s2 is a command line channel zapping (i.e. tuning) utility similar to szap but including support for S2API a.k.a. DVB API version 5, which supports DVB-S2. When using szap-s2, one instructs it to change the channel to one of a list of channels supplied in a channels.conf type file.
Note: szap-s2 requires Linux DVB driver API version 5 -- i.e. use kernel 2.6.28 or later.
