unzip

[Chiara Fregonara]

Hi,
I have to unzip lot of files coming from mvs.
The unzipped file are very large (up to 20Gb).
I've actually installed UnZip 5.50 and I've found that have 2Gb limit.
I've tryed to download the bata UnZip 6.0 but I can't compile it successfully, it ends with udefined symbols ecc.
How can I unzip my files?

Thanks
Chiara

My first thought is to check if the "largefiles" option is enabled in your filesystem. Can you confirm this is configured?

[Jannik]

if the command returns nolargefiles change it:
# fsadm -F vxfs
nolargefiles

This is how it is done:
# fsadm -F vxfs -o largefiles

To verify:
# fsadm -F vxfs
largefiles

[Chiara Fregonara]

Largefile is enabled and if the same users transfers files not zipped he can write all the files but the transfer takes too long.

The unzip gives a write error but of course the file system is not full (we have 110Gb free on it)

Thanks
Chiara

Chiara,
look to me that you have the 32bit version on unzip, you may have to rebuild as 64bit.
Perhaps somebody has a pre-built 64 bit version?

Chiara,

Looks indeed like you need unzip version 6.0 to solve your large files problem.

Would gzip/gunzip be a solution ?

here you'll find the binaries in depot format.

A lot of helpful information is here:

As alredy told I was unable to compile unzip 6 on my system.
Has anyone the unzip 6.0 binaries for hp-ux 11.11 64 bit?

I've just downloaded the latest official binaries 5.52 but the error is the same and with the -v options it says
USE_DEFLATE64 (PKZIP 4.x Deflate64(tm) supported)

What can I do?

Thanks
Chiara

I can't seem to find the beta source kit. Where did you find it?
I'd like to give it a try.
If I succeed, I'll make it available on my site

Enjoy, Have FUN! H.Merijn

I got the source here:
ftp://ftp.info-zip.org/pub/infozip/OLD/beta/unz600c.zip

Let me know if you succede in compiling it whith the LARGE FILE support (I was able to compile it only without this option)

Thanks

[H.Merijn Brand (procura]

Check if this is what you need:

http://www.cmve.net/~mbrand/unzip60c-11.11-elf64.tgz

If not, what did I miss?

# cp unix/Makefile .
# vi Makefile:

CF = +DD64 +Z -z -Ae -O -I. -DUNIX $(LOC)
LF = -o unzip
LF2 = -s +DD64

# make hpux

Enjoy, Have FUN! H.Merijn

Hi,

How about giving a try with jar utility ?

# /opt/java1.4/bin/jar -xvf

Thanks Procura, it works but non on all my files. Unzipping some file it gives this error:

Archive: cliente.zip
PKZIP for zSeries by PKWARE
skipping: cliente.data need PK compat. v4.5 (can do v2.1)

I don't know why, still investigating.

Thanks Arunvijai even if it gives this kind of error it seems to work!

java.util.zip.ZipException: invalid entry size (expected 4211106945 but got -83860351 bytes)

I didn't have idea that jar could do this.

Thanks all
Chiara
