How to pass a variable value to another server using ssh

Question

#!/bin/ksh

CTN=1
ssh -q user@host 'exec bash -s' << 'ENDSSH'
cd abc/def
./scriptname \$CTN
ENDSSH

exit;

However in the remote server, value of variable CTN is not getting passed. Please help.

It should be:

CTN=1
ssh -q user@host 'exec bash -s' << ENDSSH
cd abc/def
./scriptname "$CTN"
ENDSSH

Since you want $CTN to expanded locally you must not escape the $ and must not put ENDSSH between single quotes.
