Hi

can't unzip a gz file in TurboLinux 7.0
when i'm trying this
gunzip filename.tar.gz it always says not in gzip format
what should I do...please help me

You might want to use the file command to check that it is a gzip file.

% file bind-src.tar.gz
bind-src.tar.gz: gzip compressed data - deflate method
% file iscbind831.tar
iscbind831.tar: USTAR tar archive
% file tpa.dns.Z
tpa.dns.Z: compressed data block compressed 16 bits
%
% mv tpa.dns.Z tpa.dns.gz
% file tpa.dns.gz
tpa.dns.gz: compressed data block compressed 16 bits

You can see just because a file has a .gz does not mean it is a gzipped file. It may have changed in the way it was downloaded (or after) but kept the .gz name.

It may be that the file is simply tarred. I've had this where someone forgot to zip it but specified the extension with gz. Worth a quick check too.

Depending on the browser you used to download, the file may have already been unzipped during the download, but didn't alter the file to reflect this. You might try renaming the file from file_name.tar.gz to file_name.tar, then try untaring it.

tar xvf file_name.tar

See if that works. -mk

Hello,

sometimes, when I want to compact a file or a groups of files I use bz2, because it permits appends on the .bz2 file.

If you have a test.bz2 file, you can do something like bzip2 -9 file.x >> test.bz2.

For some jobs, thats good, for others no.
