Alternatives to Expect

Shell Programming and Scripting
1

Are there any other alternatives to using Expect script? Can functionality provided by Expect be achieved by any other scripting language?

2

a 'poor-man' implementation of the inline telnet - not exactly robust/useful...:

#!/bin/ksh
host='myHost'

    (
    sleep 3
    print "pvuser"
    sleep 1
    print "pvuser"
    sleep 2
    print "ls ~"
    sleep 1
    print "exit"
    sleep 3
    ) | telnet "${host}"
3

For what purpose?

4

Purpose is to completely stop using Expect and use passwordless ssh in bash or perl scripts to achieve same functionality as Expect.

5

ssh keys would be best. No need to store passwords in the scripts at all.

6

I am already using ssh keys but some of the script run into errors from remote host saying not on terminal cannot execute etc. So how do I emulate terminal behavior using ssh?

7

Python expect, etc... there are others... google is your friend (?)

8

ssh -t -t will force ssh to have a terminal on the remote end.
