Expect script...

Hazem Mahmoud_3 — Thu, 07 Oct 2004 12:15:24 GMT

Ok, so this is my first time using expect. I installed it and configured it fine and for the most part it's working, but I can't seem to execute any commands after I login (at least I don't think it's executing anything). I can log in fine, but it just logs out at the end, it's not showing me that it executed the "ls" command or "find" command. Any help please! This just smells of a bunny:) Here is my script:

------------
#!/usr/local/bin/expect -d

spawn /usr/local/bin/ssh root@
expect "root@'s password: "
send "\r"
expect "# "
send "find / -name TEMPFILE \r"
send "bye\r"

--------------
To execute I just run ./backups.sh

Thanks!

Try using the -f option as well, and then
embed the expect commands in a "here" file in the script:

#!/bin/ksh

/usr/local/bin/expect -d -f <set timeout -1
match_max 100000
spawn /usr/local/bin/ssh root@
expect "root@'s password: "
send "\r"
expect "# "
send "find / -name TEMPFILE \r"
send "bye\r"

EOF

Note the two lines I added as well.

Hi Hazem,

There should be some expectation after you send 'find / -name" commmand. So, modify it as

expect "# "
send "find / -name TEMPFILE \r"
expect "# "
send "exit\r"

You can also do a

set pid [spawn /usr/local/bin/ssh root@]

After send 'exit\r', you can add 'exec kill $pid' just to make sure the telnet session gets killed.
