tar doubts - problem with tar

Shell Programming and Scripting
1

The below tar command works fine for me,

tar -cvf - `find ./srcdir -type d` | (cd ./destdir ; tar -xvf - )

but this version is giving error to me:

cd ./srcdir &&
tar -cf - . |
gzip -9 |
cd ../destdir &&
gzip -d |
tar -xf -

error is: gzip: compressed data not read from a terminal. Use -f to force decompression.
For help, type: gzip -h
tar: This does not look like a tar archive
tar: Error exit delayed from previous errors

gzip is not receiving the input from the pipeline, it is lost by the cd. However some versions of cd will allow you to do something like tar cf - | cd target | tar xf -, or use a subshell (put parentheses around the cd; gzip -d | tar xf -)

Some versions of tar also have an option to switch directories when starting; with GNU tar, this is tar -C directory

Nice solution, works fine for me. Thanks a lot.
