SYNOPSIS

fm [ -h ] [ -o ] [ -q ] [ -d device ] [ -t tuner ] on | off | + | - | freq [ volume ]

DESCRIPTION

fm is a program to control the frequency, volume, and mute/unmute state of an FM radio card, using the video4linux interface introduced in 2.1.x series Linux kernels.

OPTIONS

-h
Print a usage message to standard output, and exit.
-o
Ignore frequency range limits of card. Use if you suspect that the card supports a wider frequency range than its driver believes.
-q
Quiet mode. Keeps information on station and volume from being printed on standard output.
-d device Sets device as the device to tune. The default is /dev/radio0.
-t tuner Sets tuner as the tuner on the selected device to adjust. The default is tuner 0. Most radio devices have only a single tuner.
freq
Frequency to tune the radio to, in MHz. For instance, 88.9 specifies a frequency of 88.9 MHz. AM tuner values are also specified in MHz; for instance, 530 kHz would be specified as .530.
on
Turn the radio on (unmute).
off
Turn the radio off (mute).
volume
Specify the desired volume, in percent. Not all radio devices support volume control.
+
Increase the current volume.
-
Decrease the current volume.

FILES

$HOME/.fmrc
Optional configuration file used to set default volume and volume increments, in percents. Specify default volume with a line of the form VOL percent. Specify volume increments with a line of the form INCR percent.

If this file does not exist then the defaults are 12.5% volume and 10% volume increments.
