Your can 'gunzip' to uncompress the archive.

Change directory to where you archive is

# /usr/contrib/bin/gunzip ./Managerhpux.tar.gz

Missed something....

# /usr/contrib/bin/gunzip ./Managerhpux.tar.gz

Once the file has been un-zipped you can extract from the archive.

change directory to where you wish to extract.

# tar xvf /directoryname/Managerhpux.tar

Hello,

Mr. SivaKumar, uncompress won't work, that works only for .Z files.

of course if the file isn't really a gz none of the commands will work!

file file.tar.gz
to verify format.

# file /one.tar
/one.tar: tar file
# gzip /one.tar
# file /one.tar.gz
/one.tar.gz: awk program text

awk program text.. yikes..
of course that should say gz

Hi,

If eManager35hpux.tar.gz is actually a gzipped tar file, you can use "gunzip" or "gzip -d" on it then "tar xvf". To unzip the file, you need enough space in the directory where it resides for the .gz file and the unzipped file (because the system keeps the .gz file until the unzipped file is fully unzipped).

If tight on space or you just want to extract the contents of the tar file, use:
gzip -dc eManager35hpux.tar.gz | tar xvf -

I'd always use "tar tvf" before actually extracting the contents.

"file eManager35hpux.tar.gz" may not tell you what kind of file it really is. I just ran "file" against a gzipped tar file and it said "awk program text".

Where did you get eManager35hpux.tar.gz? It's possibly corrupted. It ftp'ed from a PC, did you use binary mode? You should.

Hi

to use 'uncompress' the file, it has to end with .Z (xxx.Z) so you have to copy or move it for trying to 'uncompress'.
The file name suggests me that it is downloaded from internet.
Maybe the download was uncomplete. Try it again.
You also can check a file xxx.gz with winzip or alike.
If the file is incomplete winzip will tell it.

Hi ayanda,

no reply from you till now.
So some more informations:

zcat and uncompress (your 1. and 4. try) only works with files with extention '.Z'.
tar needs an unzipped file. Your file is zipped (or gzipped) therefor error 'directory checksum error' (3. and 6. try).
5. try doesn't work because file doesn't exists.
2. try says 'format violated':
so either the file is incomplete or the transfer was ascii instead of binary.

Hello,

Try with Gnu Zip.

Download it from here:

Ayanda,

Please give us the output of this command:

file ./Managerhpux.tar.gz

My guess is you have a corrupted file, perhaps downloaded as ascii instead of binary.
