This will actually read from stdin.

By typing, yes.

You *can* type in terminal when invoking the script with exec.

13:47:30 ~$ dash -c "read -p input: l;echo got \$l"
input:abc
got abc
13:47:35 ~$ ruby19 -e 'exec "dash", "-c", "read -p input: l;echo got $l"'
input:def
got def

I do not think so (see above).

Passing parameters is a different story: parameters (aka "command line
arguments") are passed with the execution, e.g.

13:42:30 ~$ time ruby19 -e 'exec "/bin/sleep", "5"'

real    0m6.150s
user    0m0.139s
sys     0m0.124s
13:42:40 ~$

So, what is your problem?

Kind regards
