NAME
       lif - logical interchange format description

DESCRIPTION
       LIF  (Logical  Interchange  Format) is a Hewlett-Packard standard mass-
       storage format that can be used for interchange of files among  various
       HP computer systems.  A LIF volume contains a header (identifying it as
       a LIF volume) and a directory that defines the contents (i.e. files) of
       the volume.  The size of the directory is fixed when the volume is ini‐
       tialized (see lifinit(1)) and sets an upper  bound  on  the  number  of
       files that can be created on the volume.

       HP-UX  contains a set of utilities (referred to as lif∗(1)) that can be
       used to:

	      ·	 Initialize a LIF volume (i.e. create a header	and  an	 empty
		 directory),
	      ·	 Copy files to and from LIF volumes,
	      ·	 List the contents of LIF volumes,
	      ·	 Remove LIF files,
	      ·	 Rename LIF files.

       The  lif∗(1)  utilities	are  the only utilities within HP-UX where the
       internal structure of a LIF volume is known.  To the rest of  HP-UX,  a
       LIF volume is simply a file containing some unspecified data.  The term
       LIF volume should in no way be confused with the HP-UX notion of a file
       system volume or mountable volume.

       LIF  utilities  on HP-UX currently support three file types, ASCII (1),
       BINARY (-2) and BIN (-23951).

       Three copying modes are associated with these file types:

	      If the copying mode is
			ASCII and an HP-UX file is being copied to a LIF  vol‐
			ume,  the  utility  strips the trailing LF (line-feed)
			character, and inserts two bytes of record  length  in
			front  of each record.	These records are then written
			to a LIF-formatted medium.  When copying a  LIF	 ASCII
			file  to  HP-UX the two-byte record length is stripped
			and a trailing LF is appended.	These records are then
			written	 to the destination.  In this mode of copying,
			the length of the file is preserved.  The default file
			type for this mode of copying is ASCII (1).

	      If the copying mode is
			and an HP-UX file is being copied to a LIF volume, the
			utility simply inserts two bytes for record length  in
			front  of  each 1-Kbyte record.	 A trailing fractional
			block has a count reflecting the number	 of  bytes  in
			that  block.   No interpretation is placed on the con‐
			tent of the records.  These records are	 then  written
			to a LIF-format medium.	 When copying a LIF file to an
			HP-UX file in copying mode,  the  record  lengths  are
			stripped  and the content of records is directly writ‐
			ten to the destination.	 In this mode of copying,  the
			length	of  the binary file is preserved.  The default
			file type for this mode of copying is (-2).

	      If the copying mode is
			RAW, and an HP-UX file is being copied to a  LIF  vol‐
			ume,  the  utility  simply  copies the raw data to the
			destination.  File sizes that are not  integer	multi‐
			ples  of  256  bytes are padded with nulls to the next
			higher multiple.  Therefore, When copying a  LIF  file
			to  an	HP-UX  file  in	 RAW  mode, the information is
			copied directly without any interpretation  placed  on
			the  content of the source.  The default file type for
			this mode of copying is (-23951).

       A LIF volume can be created on any HP-UX file (either regular disk file
       or device special file) that supports random access via (see lseek(2)).
       lif∗(1) utilities.  See lifinit(1) for details.	Within a  LIF  volume,
       individual files are identified by 1- to 10-character file names.  File
       names can consist of uppercase alphanumeric characters (A through Z,  0
       through	9) and the underscore character (_).  The first character of a
       LIF file name must be a letter (A through Z).   The  lif∗(1)  utilities
       accept  any  file name (including illegal file names generated on other
       systems), but can only create legal names.  This means that files whose
       names contain lowercase letters can be read but not created.

       LIF  file names are specified to the lif∗(1) utilities by concatenating
       the HP-UX path name for the LIF volume followed by the LIF  file	 name,
       separating the two with a colon For example:

	      specifies		    LIF file accessed via HP-UX device special
				    file
	      specifies		    LIF file within HP-UX disk file

       Note that this file-naming convention is applicable  only  for  use  as
       arguments  to the lif∗(1) utilities, and does not constitute valid path
       naming for any other use within the HP-UX operating system.
