That is for analog channels.  I'm looking for ATSC digital channels so I 
use "dvbscan":

usage: dvbscan [options...] [-c | initial-tuning-data-file]
        dvbscan doesn't do frequency scans, hence it needs initial
        tuning data for at least one transponder/channel.
        -c      scan on currently tuned transponder only
        -v      verbose (repeat for more)
        -q      quiet (repeat for less)
        -a N    use DVB /dev/dvb/adapterN/
        -f N    use DVB /dev/dvb/adapter?/frontendN
        -d N    use DVB /dev/dvb/adapter?/demuxN
        -s N    use DiSEqC switch position N (DVB-S only)
        -i N    spectral inversion setting (0: off, 1: on, 2: auto 
[default])
        -n      evaluate NIT-other for full network scan (slow!)
        -5      multiply all filter timeouts by factor 5
                for non-DVB-compliant section repitition rates
        -o fmt  output format: 'zap' (default), 'vdr' or 'pids' (default 
with -c)
        -x N    Conditional Axcess, (default 1)
                N=0 gets only FTA channels
                N=xxx sets ca field in vdr output to :xxx:
        -t N    Service select, Combined bitfield parameter.
                1 = TV, 2 = Radio, 4 = Other, (default 7)
        -p      for vdr output format: dump provider name
        -e N    VDR version, default 2 for VDR-1.2.x
                ANYTHING ELSE GIVES NONZERO NIT and TID
                Vdr version 1.3.x and up implies -p.
        -l lnb-type (DVB-S Only) (use -l help to print types) or
        -l low[,high[,switch]] in Mhz
        -u      UK DVB-T Freeview channel numbering for VDR
