I have a task where I need the shell to execute something immediately after user's input.
Example:
root@hq> pwd
<my user defined function>
/home/users/home40/spandiya
root@hq>
I need my defined function to run immediately after user inputs "pwd", how do i do that? I do not want PROMPT_COMMAND
which is executed by shell just before PS1.
I need my script to be executed immediately after user input.

Here is a work-around using trap DEBUG
:
mycmd() { tty; echo "custom command"; }
trap 'mycmd' DEBUG
$ pwd
/dev/cons0
custom command
/home/user
mycmd
function runs just after user input but before executing user's entered command.
