Help with GZIP

[Ragni Singh]

Hello all, what command or how can I zip up these huge files?

-rw-r--r-- 1 root other 13201392128 Jul 13 20:10 f480a_local.tar
-rw-r--r-- 1 root other 33286085632 Jul 13 17:52 f480a_raid1.tar
-rw-r--r-- 1 root other 13312 Jul 13 22:49 f480a_raid2.tar
-rw-r--r-- 1 root other 68500506112 Jul 13 21:18 f480a_raid4.tar


I tried doing and get the following message..

[root@db2.pmonline.com]/raid1#gzip f480a_local.tar
f480a_local.tar: Value too large for defined data type

Pipes are your friend.

gzip -cd f480a_raid1.tar | tar tvf -

to do a listing (assuming a tar-gz file).

gzip does not support more than 2GB size.Use compress instead.

compress filename

What ?! gzip should have no problems with large files under Linux!

.. and now that I've read this again, I think i told you the wrong direction..

gzip < f480a_raid1.tar > f480a_raid1.tar.gz

Using this method should work regardless of file size.

If it is a largefile issue, what version of gzip are you using ? It'd have to be old to not support large-files. We're talking pre-2002/2001.

As usual, it might help if you showed the
actual command you used, and told us the
version of the program you're using.

gzip -V

Try bzip2

[option -1 to 9, 9 for best compression)

have a look at http://www.mkssoftware.com/docs/man1/bzip2.1.asp

I have a feeling this is Solaris. Regardless, you need to update gzip.

hi,

in the worst case, you may also choose to split each file into more *manageable* sizes before doing the gzip.

hope this helps too!
kind regards
