how can I make auto run through script the comand SU - username
and given password

sysgate · #2 (**permalink**) 09-20-2007

with TCL/expect - drawback - you need to store root pass in file. Example :

Code:

spawn su -
expect ?assword:
send "root-pass-here\r"

thaks Sysgate but the code expect not work

Code:

#!/usr/bin/expect  #--- the place for expect executable, replace respectively on your system

set timeout -1  #--- sets the timeout to unlimited

spawn su -  #--- invoke system command, takes little time

expect assword:  #--- what to expect, the word password should be escaped

send "$pass\r"  #--- send string to expect buffer

send "exit\r"
expect eof  #--- both self-explanatory
