NAME

SYNOPSIS

DESCRIPTION

If no command is given, then cdcontrol enters an interactive mode, reading commands from the standard input.

The following options are available:

-s

Silent mode. Do not print table headers and human readable comments.

-v

Verbose mode. Print as much information as possible.

-f device

Specify a device, such as /dev/cd0. Both absolute path and relative to /dev filename are possible. The -f option overrides CDROM. If neither CDROM nor the -f option is specified, cdcontrol tries opening first /dev/cdrom, then /dev/cd0.
