Say I have a script that will be run on a remote machine. While running, the script computes some value. I want to prompt the user so she can change this value if needed. Is this possible?
I am running the script like: ssh $usr@$machine 'bash -s' < a.sh "param1" "param2"
In a.sh the read alternateValue
function call seems to be ignored.
Or can anyone suggest a different approach?

The read
statement reads data from stdin, but you are redirecting stdin in your command line with the <
operator, so read
isn't going to do anything useful.
What if you were first to copy the script over to the remote host, and then run:
ssh $usr@$machine 'bash /path/to/a.sh param1 param2'
Because there is no redirection happening here, read
would work without a problem.
