tar and extract in a single line

[sandeep t]

I have 4 lines of code where I tar the doc files and then extract to some other location.

cd ${INSTALLER_BUILD_ROOT}/doc/
tar cvf build_doc.tar *
cd $DOC_ROOT/doc
tar xvf ${INSTALLER_BUILD_ROOT}/doc/build_doc.tar

Can I optimize it and reduce to a single line?

Do you want to end up with an additional archive in $DOC_ROOT or do you merely want to copy the files?

cp ${INSTALLER_BUILD_ROOT}/doc/* $DOC_ROOT/doc/

Actually, I want to just copy the files. But I can't use cp command because I'm doing this copy on the network drive location which starts with //, and cp command ignores the Case. ( for ex: it will copy the Hello as hello, which I do not want)
I want to use tar only.

Use the pipe. That's what it's there for.

# cd ${INSTALLER_BUILD_ROOT}/doc/; tar cf - . | (cd $DOC_ROOT/doc; tar xpf -)

Thanks, this is what I was looking for!
