Unable to get terminal prompt when executing script via ssh

Question

I have the below script that works fine when run locally

cat /tmp/input.sh

                echo -n ">> "
                read env
                exit;

I get the command prompt when i run as below.

$/tmp/input.sh | echo "whatever"
$

All good so far. The problem occurs when i run this script via ssh

ssh wladmin@myhost /tmp/input.sh | echo "whatever"

As you see i expected control on the command prompt terminal i.e $ but unless i press Crtl + C or others i do not get the command prompt to type further.

I tried ssh -T option but that did not help.

Can you suggest what needs to be done?

The echo "whatever" is killing the script at the echo -n ">> " line, since it is not accepting any input coming from the script - therefore the read env never happens. I do not see why you would be doing |echo like that but carrying on regardless - When you do the ssh, only the input.sh script gets run remotely - and it does not "know" that text to stdout will be rejected. To get the same effect, run everything remotely, i.e. quote or escape the |

ssh wladmin@myhost /tmp/input.sh \| echo "whatever"
