What version of gzip do you have installed?

whence gzip

what

You might try a newer version or this may be a feature.

May be you can rename the file (remove the extension) and then try zipping it..

is this the problem with file size??
bacuase the file i am tring to zip is of above 1 GB....

Could be filesize if you fail out at 2 GB. Thats the max on filesystems created without the largefiles option.

check as whether the file is above 2gb in size for which

1.check as whether the file system supports largefiles.

2.Use gzip latest version above 1.3.1

What type of file is is, and - sorry to ask - do you want to compress the file, or do you want to uncompress/extract it as if it were a (compressed) archive of some sort.

First thing to do is to find out what the type of the file is:

# file blah.bkp

If that returns GZIP, BZIP2, PACK, COMPRESSED, or ZIP, you will need the corresponding utility to uncompress it

# gzip -d file.xxx
# bzip2 -d file.xxx
# unpack file.bkp (very unlikely)
# uncompress file.xxx
# unzip -l file.bkp

unzip does compress and archive in one phase, which you cannot split

Now look at the type of file.xxx

# file file.xxx

If it says TAR or CPIO

# tar tvf file.xxx
# cpio -itv
to see what the content of the archive is. If cpio comes with a phase error, try

# cpio -itvc
In all cases it's wise to use the GNU versions of the utilities, because they can deal with non-native or weird formats (other CRC checksums etc) way better than HP's native tar and cpio

Enjoy, Have FUN! H.Merijn

No one mentioned it, so:

To check largefiles support:
fsadm /path/to/filesystem

To enable largefiles support:
fsadm -o largefiles /path/to/filesystem
