HI：
How can i use use gzip to compress and tar to append the other file:
here is is a testcase :
file :test1 test2
:~/testtar # tar -czf 1.tar.gz test1
:~/testtar # tar -rzf 1.tar.gz test2
Could you use tar czf 1.tar.gz test1 test2 ?
tar: Cannot update compressed archives
Try `tar --help' or `tar --usage' for more information.
However tar -cf
tar -rf can work fine.
I am thinking find a way useing gzip to compress and tar then and
need to append any time .
Thank you
