MOVER Utility

Transferring HFS-Named Files With MPE Attributes

by Steve Elmer
Commercial Systems Division

Overview

Beginning with the MPE/iX-Express 2 based on General Release 5.0, a new TELESUP utility, MOVER.PRVXL.TELESUP, is available. The MOVER utility is essentially an upgrade to the UHAUL utility that allows HFS files to be archived while providing expanded features. The utility is documented in MOVER.DOCXL.TELESUP.

Prior to this Express 2 Release, transferring files via the network has posed many difficulties when using HFS names for files. There have also been problems with new file formats and preserving MPE file attributes.

Each of the existing archive utilities falls short of the MOVER utility for the following reasons:

The shell's tar utility can handle HFS names and the new file types, but drops the MPE file attributes.
The STORE command does not support creating a disk file, so even though it handles all the problems, it cannot be used to transfer files over a network.
The UHAUL utility in TELESUP can handle the new file types and all the MPE file attributes, but cannot handle the HFS name space.

MOVER Features

The MOVER utility combines and compresses multiple disk files into a single disk file. This file can then be easily transported to another system through products like NS/3000 or the ARPA FTP program. Once transported the MOVER utility can again be run to reconstruct the original files.

Following is a list of the MOVER features:

Keeps many related files together in one easy to transport location (like patch files and their job streams).
Reconstructs files exactly as they were originally created including:
- File type (including symbolic links)
- File code
- File limit
- Record size
- Record format (including byte-stream)
- Blocking factor
- Extent size
- Number of extents
- Number of user labels
- User label contents
- Security information (as POSIX user/group/other rwx bits)
Compresses and simplifies moving multiple files from one HP 3000 to another. (ASCII data is anywhere from 30-80% compressible. Binary files are usually about 5-15%.) This data compression can reduce data transmission times.
Uses the byte-stream record format and has no dependencies on MPE file attributes for the archive file itself.
Recognizes directories and automatically recurses them.
Uses a LISTF like format to display file information for every file archived.
When privileged, can archive some common database files.
Supports both relative and absolute filename modes.
To archive files with only relative names, simply use relative names in the fileset. To archive files with absolute names, use absolute names in the fileset.
For example, if the Current Working Directory (CWD) is "/" then the command

MOVER -c foo .

archives every file on the system using relative names. The command

MOVER -c foo /

would archive every file on the system using absolute names. Files archived with relative names can be unarchived into any directory. Files archived with absolute names are unarchived only to their original filename.

MOVER Syntax

The MOVER program is a POSIX program and takes a POSIX syntax. When you use the shell to invoke MOVER it expands filename wildcards appropriately for MOVER's use.

To create a new archive, use

MOVER -c archive_name file file...

To extract files from an existing archive, use

MOVER -x archive_name

To list the files in an existing archive, use

MOVER -t archive_name

To allow MOVER to manipulate privileged files, add "0" to the options. For example, the following command

MOVER -c0 foo .

would archive privileged files in the CWD.

MOVER Safety

To remove PM capability from MOVER, use the linkeditor:

MPEIX:linkedit LinkEd> altprog MOVER;cap=ia,ba

The utility still functions, but the "0" option is ignored.

The MOVER utility overwrites files by default. Use care when unarchiving files, especially absolute named files.

If you need MOVER then download mover55.prvxl.telesup
Use ftp, Reflection Binary, or other binary transfer method to upload it to your HP3000

ftp> bin
200 Type set to I.
ftp> quote site posix on
200 POSIX command ok.
ftp> put mover55.prvxl.telesup mover55.telesup
200 PORT command ok.
150 File: mover55.telesup opened; data connection will be opened
226 Transfer complete.
