thanks, but -a option in tar HP-UX 11.00
doesn't work.

[Robin Wakefield]

With tar, it's the -r option

tar -r (This option can not be used if archive is tape)

you can create file1.gzip then include this zipfile with new files to be zip.

Use the r flag to append files to an existing tar file.

You can't append to a gz file but if it's a compressed tar archive then you could:-
- gunzip the file
- tar r to add files
- gzip it again.
