extract error tar.gz
 

I saved my downloaded Mozillafirebird.tar.gz file in /usr/local/src.

To extract tar.gz..
Run the following commnd in /usr/local/src
[root@localhost src]# tar -xvf MozillaFirebird-0.6-i686-pc-linux-gnu.tar.gz
tar:this does not look like a tar archive
tar:skipping to next headers.
tar:archive contains obsolescent base-64 headers.
tar:error exit delayed from previous errors.
why this error message occurs??

Corrupted download?

Look at the file:
file filename
SO
file MozillaFirebird-0.6-i686-pc-linux-gnu.tar.gz
Also look at the size. Maybe there was an error when it was copied over, you may have been out of space (are out of space) look with:
df -h
....Nevermind.
I see you missed the Z for the gz compression:
tar xvzf filename.tar.gz

Cool

You are doing it wrong... it's a gunzip. The file name ends with gz right? do like this first

gunzip MozillaFirebird-0.6-i686-pc-linux-gnu.tar.gz

then untar it

tar -xvf MozillaFirebird-0.6-i686-pc-linux-gnu.tar

Or just add the z in the tar command:
tar xvzf

:)

Cool

tar -xvzf filename.tar.gz
