Hi,
x='\'
The above command works. But the following command doesn't. It doesn't
make sense to me why the above command should work without closing the
initial single quote. Could anybody help explain why this syntax
should be correct? Thanks.
x="\"
A single quote cannot be escaped; a double quote can be.
