Hi Vijay,
your script didn't work for me with /bin/sh so I modified it, and
changed the logger's to echos so that I don't pollute my logs. I have
found a small race in your script and I'd like to address it with an
expect script I wrote for you:
#!/usr/local/bin/expect --
spawn ./vijays-mypasswd.sh
expect Changing
stty cooked
expect Old?password:
send \n
send "^C"
stty raw
expect -re ^Unsuccessful
Also I have provided to you my version of vijays-mypasswd.sh
----
#!/bin/sh
trap "" 2
/usr/bin/passwd -l
if [ $? -eq 0 ]; then
echo "Unsuccessful attempt to change password"
else
echo "Changed login password"
fi
----
Notice the trap, hash it out to see what doesn't happen.
Regards,
-peter
