vmsprep - VMS tape preparation aid
vmsprep [-] [name ...]
Vmsprep traverses hierarchies of files and prepares them for
transportation to VMS. Since ANSI standard tapes (the VMS standard) do
not allow hierarchy, this program provides a method of flattening the
hierarchy onto a tape in such a way that it can be unpacked on VMS to
recreate the same tree structure.
For reasons best not described here, vmsprep will attempt to exclude all
RCS and SCCS archives by ignoring all files or directories named 'RCS' or
'SCCS', or files starting with 's.' or ending in ',v'.
The output of vmsprep is a pair of files vmsprep.namelist and UNPACK.COM.
vmsprep.namelist is a list of files to be placed on the tape in the
format required by ansitape. If the first argument is '-' instead of a
file or directory name, vmsprep will instead send the namelist to
standard output, and place UNPACK.COM in /tmp to avoid attempting to
write in the current directory. All of the files except UNPACK.COM will
be placed on the tape under cryptic names. UNPACK.COM is a VMS command
script which will recreate all of the necessary directories and then move
the cryptically named files to their proper place.
A typical sequence would be:
vmsprep - tree1 tree2 file | ansitape cln trees -
Then on the VMS machine
mount MFA0: trees
copy MFA0:*.*.* *
A warning is reported if a file or directory name contains a character
not permitted in VMS names. The offending character is replaced by 'Z'
and vmsprep continues.
Extra periods in file names may not be dealt with optimally.
All files and directories to be moved must be descendants of the current
working directory. Absolute path names and paths containing ".." will
produce unpredictable results.
Since vmsprep uses find(1) internally, it does not follow symbolic links.
The exclusion of RCS and SCCS files should be controlled by a command
Assumes VMS v4.0 or greater for long file names.
