Here is information that you should know before you copy files to tape with the tar command:
You can use file name substitution wildcards (? and *) as part of the file names that you specify when copying files. For example, to copy all documents with a .doc suffix, type *.doc as the file name argument.
You cannot use file name substitution wildcards when you extract files from a tar archive.
$ tar cvf /dev/rmt/n filenames
Indicates that you want to create an archive.
Displays the name of each file as it is archived.
Indicates that the archive should be written to the specified device or file.
Indicates the files and directories that you want to copy. Separate multiple files with spaces.
The file names that you specify are copied to the tape, overwriting any existing files on the tape.
$ tar tvf /dev/rmt/n
For more information on listing files on a tar tape, see How to List the Files on a Tape (tar).
