- NAME
- xad2lha 1.1
-
- SYNOPSIS
- xad2lha FROM/A,TO,PASSWORD/K,NE=NOEXTERN/S,QUIET/S,HEADER0/S
-
- DESCRIPTION
- xad2lha extracts data from other archives and stores it in an
- lha archive.
- This program transfers all additionally information, like UNIX
- owner stuff and protection bits.
-
- FROM specifies the file archive that should be handled.
-
- TO is the name of destination lha file. When not specified, the
- source name extensions are stripped and .lha is added.
-
- PASSWORD can be used to supply a password for unarchiving of
- encrypted archives. This argument requires the keyword PASSWORD.
-
- NOEXTERN prohibits the use of external clients for
- recognition purposes.
-
- HEADER0 uses header level 0. This header is older and does not
- have special information.
-
- The QUIET option makes the program really silent.
-
- DATA FORMAT
- This tool normally creates files using header level 2.
- Uncompressable files are stored using -lh0-, all the others use
- -lh5- identifier. Directories use -lhd- identifier. The OS-ID is
- set to 'A', which is used by other Amiga lha programs.
- Following header information is included:
-
- 0x00 CRC always
- 0x01 file name except it is an directory
- 0x02 directory name except the file name has no directory part
- 0x50 UNIX protection bits if there are group or other bits
- 0x51 UNIX owner ID's only if user or group ID is not zero
- 0x52 UNIX group name if exists
- 0x53 UNIX user name if exists
- 0x54 UNIX date always, except if source archive had no
- date (no UTC correction, but local time)
- 0x71 comment if exists
-
- When HEADER0 ist used, then directories are stored using -lh0- and
- a slash at name end. Comments are included in file name field and
- are seperated by a zero byte. Additionally header information is not
- supported with that format.
-
- Standard protection bits and time stamp are always included in both
- headers.
-
