Top Forums UNIX for Advanced & Expert Users SU command in non interactive mode Post 302138609 by user1323 on Tuesday 2nd of October 2007 03:37:20 PM
Old 10-02-2007
the response is:

spawn /bin/su
Password:
su: Sorry
send: invalid spawn id (4)
while executing
"send "/bin/echo Hello>>/tmp/readfil\n""
(file "exp" line 7)

If I didn't have a whitespace in expect "\r\n", the program ran but nothing being created in /tmp/readfil.
