NAME
       dds2index - tool to create an indexfile for the use of

SYNOPSIS
       dds2index [options]

DESCRIPTION
       dds2index creates an index file that is required by the file extraction
       utility dds2tar(1).  It works  on  tar  archives	 stored	 on  dds  tape
       devices	(DAT).	 Since the file structure of the tape archives is used
       to extract the files, the archive must be an uncompressed tar  archive.
       But  compression by the transparent signal processor of the tape device
       is allowed.

       The index created by dds2index is written  to  stdout  by  default  and
       should  normally	 be  stored on hard disk as indexfile for later use by
       dds2tar(1).

       The default tape device to read from is /dev/rmt0, which may  be	 over‐
       ridden  with  the environment variable TAPE, which in turn may be over‐
       ridden with the -f device option.  The  device  must  be	 a  SCSI  tape
       device.

OPTIONS
       -f devicefile
	      device of the tape archive. Must be a character special file.

       -t indexfile
	      write the index to indexfile, not to stdout.

       -z,--compress
	      write the index in (gzip) compressed mode.

       --help print  some screens of online help with examples through a pager
	      and exit immediatley.

OPTIONS you didn't really need
       -b, --block-size
	      Set the maximal blocksize, dds2index can handle.

       --z, --no-compress
	      Don't filter the archive file through gzip.

       -v,--verbose
	      verbose mode. Print to stderr what is going on.

       -h,--hash-mode
	      Print a hash sign '#' to stderr for  each	 MB  read  from
	      tape.

       -V,--version
	      Print  the version number of dds2index to stderr and exit
	      immediately.

EXAMPLES
       Example of getting the index from the default tape /dev/rmt0 and
       storing it in file archive.idx:

	      dds2index -v -t archive.idx

WARNING
       This  program  can  only	 read records (tar is calling them tape
       blocks) up to 32 kbytes. A bigger  buffer  will	cause  problems
       with the Linux device driver.

ENVIRONMENT
       The  environment variable TAPE overrides the default tape device
       /dev/rmt0.

FILES
       /dev/rmt0     default tape device file. Must be a character spe‐
		     cial file.
