dds2index
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 overridden with the environment variable TAPE,
which in turn may be overridden 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.
ENVIRONMENT
The environment variable TAPE overrides the default
tape device /dev/rmt0.
FILES
/dev/rmt0 default tape device file. Must be a
character special file.
