remote script execution from local script linux doesn't stop for remote script prompts

Question

script abc.sh is on machine M1 and xyz.sh is on machine M2

script abc.sh:

#!/bin/bash
ssh -l user1 host.com ./xyz.sh -b1 arg1 -b2 arg2

script xyz has certain user prompts like pwd etc

When I execute script bc.sh from machine M1, it keeps looping with the xyz.sh script's user prompt on the terminal. It doesn't stop for user input.

Below is what I am trying to execute:

./abc.sh -a1 arg1 -a2 arg2

ssh isn't allocating a tty. Add -t to the ssh command.

I had tried ssh -t option like below, same result. #!/bin/bash ssh -t user1@host.com ./xyz.sh -b1 arg1 -b2 arg2 – S.Singh Jun 26 '16 at 15:10
Does `-tt` fix it? Otherwise xyz.sh may be trying to detect if there is a tty in an odd way. – Mark Wagner Jun 29 '16 at 20:27
