Zip utility

Mike R Smith — Thu, 25 Jun 2009 13:01:15 GMT

I am running ZIP 2.2 on VMS 8.3 using an account that has all privs. I am trying to perform a zip of several files into one and delete the files that were zipped.

Initially I thought a zip/delete was the answer but then I realized I was reading the doc wrong. I then attempted the zip/move which still does not remove the source files. The zip works just so you know.

I would appreciate it if someone has the syntax for this. I am currently doing:

$ zip/batch='input_file /move filename.zip

Seriously? That's before my time, and
probably has all kinds of bugs which have
been fixed in the intervening decade.

> [...] The zip works just so you know.

Not really. Trust me.

"-m" or /MOVE should do the job. If you have
a problem with Zip 3.0 or later, please
re-complain.

Note: UnZip 6.0 is available, too.

Current versions offer large-file support,
faster I/O, bzip2 compression, fewer bugs,
...

I just got here 4 weeks ago, zip 2.2 is what was here when i walked in. Given time i could look into installing a new version but that would take time due to tight regulations on installing anything. Thanks for the reply.

Hey, I might look into it, but the oldest
source kit I have is 2.3 (which has enough
bugs to satisfy almost anyone), and it dates
from 1999. I could try to locate the source
for 2.2, but that would take time, and if
you have tight regulations on installing
anything, then I assume that any fixes for
version 2.2 would be as unwelcome as a whole
new 3.0 (which I'd expect to work).

Move to current zip, and try it there. (2.2 is from around 1997 or so, and it features a wealth of known OpenVMS bugs, and I'd definitely expect it won't deal at all well with ODS-5 disks and extended file names.)

As for syntax with most of these sorts of Unix-style commands, I usually try something like:

zip -h

or

zip -?

In the case of zip, the qualifier -h is available.

FWIW, the OpenVMS port of zip and of unzip do offer DCL-style syntax, but (given my use of zip and unzip all over the place) I tend to prefer use of the foreign-command syntax.

If you can't get off of zip 2.2 and for whatever justification is used to trump the "we're still on v.ancient" and "well then upgrade to current" discussion (and I really don't care why that's the case), then (here) use a DELETE command after the zip and move on to the next problem.

The OpenVMS FAQ http://www.hoffmanlabs.com/vmsfaq has some information on locating various tools including pointers over to sites with zip and unzip. (Though Steven has already provided these.)

And if you're zipping OpenVMS files, always use the "-V" option as this preserves the OpenVMS file metadata.

And, nowadays, "-h2" (/HELP = EXTENDED), if
you need reading material and can't find
"zip.txt".

Always, unless you plan to take the archive
to a non-VMS system, and you're using a Zip
older than 2.31 (May 2000). (Just one of
those many bugs...)

On the bright side, even the CLI "/MOVE"
qualifier works these days:

But if you like 2.2 better, it's ok with me.

Best solution appears to be to upgrade.

Right. In fact, if you have an ODS5 extended
file name with sufficiently funny characters:
" : \ |
then you actually need Zip 3.1b (or newer,
still in pre-release ("BETA") form).

Never trust the documentation, I always say.
(_Now_, I always say that, having learned my
lesson.)
