Support for gzip and gunzip

[Michael Piccirilli]

We are an HPUX11/i user with MicroFocus Cobol.
The master Files for our application are idx8 format. Can we safely gzip and ungzip these?

We had heard that over 2 GIG this was some kind of problem. We have our file systems defined for large files. Some of our master files are as large as 24GIG. We have gzipped some of these down to 4GIG.

Thanks

HI

There is a version of pkzip for HP-UX, ver 2.1 I think.

Free to download and instals without a reboot.

Lots of sites have it.

You must have a newer version of gzip than what is shipped with HP-UX in order to work with files over 2GB. It sounds like you've already got that though.

Check the new versions of gzip to see what size files they support. It sounds like you should be OK, since you've already gzip'ed some of them down to 4GB without a problem. The next thing I'd try is to gunzip it and make sure it still works.

Michael,

I believe the newest version of gzip allows for files greater than 2gb. It can be downloaded from:
