Hi every one ,

I was confuse to use gzip in shell.
You see below. I can use zip -gj make test.tar include the
testfile and the test1file
However , use gzip make the test_gzip.tar.gz NULL.
I see man and use gzip -c file >> tarname. to add a file to a tar file .
Can anyone tell me why?
You can let /root have two sample file testfile test1file


#!/bin/sh

anse='/root/test.tar'
anse_gzip='/root/test_gzip.tar.gz'
test='/usr/local/sbin/testfile'
test1='/usr/local/sbin/test1file'

zip -gj $anse $test
zip -gj $anse $test1

gzip -c $test >> $anse_gzip
gzip -c $test1 >> $anse_gzip

I think gzip can do what zip can do in linux .

If I just do
gzip -c testfile >> test_gzip.tar.gz

It can create the test_gzip.tar.gz file But can't include any file .

Hi,
gzip is a compressor, not an archiver as tar. zip is an archiver and compressor. So maybe you could use tar with the z option to compress?

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
tar: Cannot update compressed archives
Try `tar --help' or `tar --usage' for more information.
