Here is what happens in bash shell:
$ echo "${X}" > ${Z}
bash: ${Z}: ambiguous redirect

Perhaps I am misinterpreting your question; however, if I
define both
${X} and ${Z} in a script prior to running your snippet, I
do not
receive any error message. Could you show more info on how
you are
attempting to run this snippet?


$ X='

XX1=YES
XX2=YES
'

$ echo $X
XX1=YES XX2=YES
$
$ Y='

YY1=YES
YY2=YES
'

$ echo $Y
YY1=YES YY2=YES
$
$ echo "${X}" > ${Z}
bash: ${Z}: ambiguous redirect

I want to append all variables in X and Y into Z so that "echo $Z" should be:
XX1=YES XX2=YES YY1=YES YY2=YES

I'm doing everything in command line not using any scripts.


That's not how you set a variable.  Do it like this:

Z="${X} ${Y}"

You're mixing up variable initialisation with output to files.

        Cheers,
