Unzipping the file

[Girish_17]

Hi all,
This could be an silly question but in a hurry.
I would like to know the way to unzip the file with .tgz extension.
Gunzip doesn't work ... what do i use for it??
Thanks and regards,
Girish

/usr/contrib/bin/gzip -dc file.tgz|tar xvf -

Hi Girish,

Use gzip (See man for more details):

#gzip -d

Best Regards,

Hi,
Like above or with gzcat | tar -xvf -


All the best

Thanks a lot RAlph, Eric and VIctor for your prompt responses but this is what is get :

gzip: hpux_800_11.23_12210248.tgz: unexpected end of file
Tar: error! blocksize changed

What do you suspect...!
Thanks and regards,

Use GNU tar, if you can get it, it has automatic correction for that type of error.

GNU tar 1.15 was released yesterday, and it has automatic compression detection! Yeahh!!! No more need for -z -Z or -j

The error/warning can probably be ignored, you can check this with

# tar tf BUNDLE11i_B.11.23.0409.3.depot

If that does not yield any error, the extract was fine. Otherwise, you have to re-fetch hpux_800_11.23_12210248.tgz because it is probably an unfinished download

Enjoy, Have FUN! H.Merijn

Hi Girish,

The .tgz file you tried to down load was not completed it seems. Use a download manager viz.Download Accelerator Plus for download which gives a better continuity in download. You can also resume downloads using such utilities incase u loose the connectivity during ur download.

Try downloading the file again.

Merijn,

wow really good news the auto compression detection. :-)
I always used to forget the -j switch for bzip2 packed archives with GNU tar.

New GNU cpio-2.6 just uploaded to my site. Give it a few hours to spread to the mirrors. GNU tar-1.15 is about to follow pretty soon

Enjoy, Have FUN! H.Merijn
