You can specify an argument for the --file=archive-name (-f archive-name) option whenever you
use tar; this option determines the name of the archive file
that tar will work on.
If you don't specify this argument, then tar will use a
default, usually some physical tape drive attached to your machine.
If there is no tape drive attached, or the default is not meaningful,
then tar will print an error message. The error message might
look roughly like one of the following:
tar: can't open /dev/rmt8 : No such device or address tar: can't open /dev/rsmt0 : I/O error
To avoid confusion, we recommend that you always specfiy an archive file
name by using --file=archive-name (-f archive-name) when writing your tar commands.
For more information on using the --file=archive-name (-f archive-name) option, see
section Choosing and Naming Archive Files.
