My main concern is to extract all lines of virtual host block related to given sites in shared httpd server and trnsfer it to remote vps's httpd conf file. It seems so that you try to write some characters that are treated by like special characters.

You must escape them with ''. If you want just add lines line1 , line2 , line3 seprated with newlines try. Thank you for additional information. That is a command substitution here, but must be a normal interpolated string.
