Unix shell events?

Question

Is there any way so that i can echo password when asked for in unix shell without use of external binaries ? Something like simple function triggered when password prompt is displayed

Answer 1

Short answer: no.

Slightly longer answer: the usual shells, sh, ksh, csh, tcsh, bash do not have any hooks for you to hang actions on (OK, so bash2 has context sensitive tab-completion).

On the other hand. The shell is just a program. You can replace it. If you can really say what you want to do you can hack and existing shell or write a new one to get the desired behavior...

Answer 2

Are you aware of Expect?

Perhaps this falls in the "external binaries" category, but if it does, then your question needs clarification.
