These don't mean the same thing - even in shell. The && requires truth.
Hence the reason this:
tar cBpf - . | ( cd /dest/dir && tar xBpf - )
is *so* much safer than this:
tar cBpf - . | ( cd /dest/dir ; tar xBpf - )
The former requires that you be able to cd to /dest/dir first before
untarring. The second one doesn't, meaning you can potentially corrupt
all your data by untarring right back over the top of it.
Sometimes braces and brackets are a Good Thing... ;-)
