===Zip===

====Zip and Unzip files====
Use the zip program to add files to a zip archive. Make sure you are using version 3 if you want to Zip files greater than 2GB (contact Scanco to install v3 if necessary).
<pre>
$ ZIP myzip.zip myfile.txt;1	                !Adds myfile.txt to myzip.zip.
$ ZIP "-V" myzip.zip myfile.txt;1	        !Adds myfile.txt;1 to myzip.zip.  The "-V" maintains the OpenVMS version number.
$ ZIP "-V" myzip.zip [.subdir...]*.*;*	        !Adds all files within subdir to myzip.zip, maintaining their version number.
$ ZIP	                                        !Displays the help for the zip command.
</pre>

Use the unzip program to unzip an archive.
<pre>
$ UNZIP "-V" myzip.zip		                !Extracts myzip.zip, maintaining the OpenVMS structure.
$ UNZIP		                                !Displays the help for the unzip command.
</pre>

====Transfer Zip between Scanco systems====

Files must be zipped before transfer by e-mail or ftp because important attributes will be lost in the transfer otherwise.

To transfer files from system A to B, do the following.

On system A:
<pre>
$ zip "-V" for_calgary.zip uctd:UCT_SAMPLES_TORONTOXT.DAT  ! for each filename
$ zip "-V" for_calgary.zip uctd:UCT_MEASUREMENTS_TORONTOXT.DAT
</pre>
This will add both files to the same zip file.

Note: "-V" is very important, it must be capital V!

Transfer the file by e-mail, or by ftp.

On system B:
<pre>
$ unzip -j for_calgary.zip  ! to unzip on your end them (-j to 'junk' the original file path)
</pre>

====Unpack Zip sent by Scanco====
In the .zip file, you'll find a .sav file. Unzip the .zip just by saying

<pre>$ unzip xxxx.zip</pre>

Then:

<pre>$ backup/log xxxx.sav/sav disk3:[steve.devel.temp]</pre>

and it will unpack everything into <code>disk3:[steve.devel.temp]</code>

Or:

<pre>$ backup/list xxxx.sav/sav</pre>

and you see what's in the .sav.

Then:

<pre>$ backup/log xxx.sav/sav/sel=[andres.uct.ipl_for_cust...] disk3:[steve.devel.cipl...]</pre>

and it will create the same directory tree in <code>steve.devel.cipl</code> as it was when I 
packed it into the .sav.

====Tips for making and unpacking SAVSETS====
Separate all "input" files with comma, and no space in between (space separated parameters) :

<pre>
$ backup/log D0014097.RAD,D0014097.SCV myfiles.sav/sav
</pre>

You may want to consider to only take the newest/highest file version:

<pre>
$ backup/log D0014097.RAD;,D0014097.SCV; myfiles.sav/sav
</pre>

When unpacking a SAVSET, if you want the directory structure to be maintained, do something like this:
<pre>
$ BACKUP/LOG ACKNEE_HUMAN_2020-02-18.SAV/SAV/SELECT=([BONELAB.PROJECTS.ACKNEE...]*.*) DISK4:[BONELAB.PROJECTS.ACKNEE...]
</pre>

Extracting an archived SAVESET back onto the VMS system in location different from where it was originally located, for example putting it
on DISK7:[XTREMECT2.EXTERNAL] instead of DISK4:[BONELAB.PROJECTS], do the following:
<pre>
$ SET FILE/ATTR=(RFM=FIX,LRL=32256) UBC_HUMAN_2024-03-25.SAV
$ BACKUP/LOG UBC_HUMAN_2024-03-25.SAV/SAV/SELECT=([BONELAB.PROJECTS.UBC...]*.*) DISK7:[XTREMECT2.EXTERNAL.UBC...]
</pre>
