Hi
I am unable to open through "vi" as well unable to gzip the file. Its giving "Unknown Error" message.

Hi,

If I remember correct there was a size limit in older versions of gzip. Try to install a more recents version. (link is below)

'vi' on a 2.5 Gb size file will never work. That's just too big for that editor.

a compressed file cannot be edited with vi

file size doesn't matter if you compress pipewise

# gzip -9 < large_file > file.gz

GNU gzip has lifted the file size limit long ago. Get the newer version (1.3.5) from the link posted above, or from my site: http://mirrors.develooper.com/hpux/downloads.html where I have it available for HP-UX 10.20 through 11i

You can also compile it from source yourself. Get it at ftp://alpha.gnu.org/gnu/gzip/

Hi,

vi won't be able to open such a huge file and add the fact that it is a compressed file. Try to get a newer version of gzip.

Isralyn, what does your post add to this thread? You just repeat the info already passed in the previous two posts.

No points for this post please.

Hi,

are you sure it's a gzipped file?
With 'file ' you'll get an information if it's zip or tar or others.

hi,

is it a text file?

if yes, you may also wish to "split" the file into multiple ones and use "vi" as you wish...

e.g.
split myfile output

then
vi output*

then when you reach end of the currrent file, switch to the next by doing:
"Esc"+":n"

hope this helps too!

Hi Saraswathy,

It may not be an issue with largefiles being enabled in /etc/fstab.

Try splitting the file and gzip the splitted files.

Should be something like:
split -b1000000k $path/$file.tar $path/$file.tar_
/usr/contrib/bin/gzip -v $path/$file.tar_*

To restore the initial file, use cat file1 file2 >large_file after unzipping.

This should work.
