[SOLVED] Help with expect command and multiple arguements

genderbender · 10-04-2010, 05:35 AM

I have the following code which I've thieved from here, there and everywhere:

Code:

[root@localhost /]# cat autossh
#!/usr/bin/expect -f
set ipaddr [lrange $argv 0 0]
set username [lrange $argv 1 1]
set password [lrange $argv 2 2]
set command [lrange $argv 3 11]

set timeout -1
spawn ssh $username@$ipaddr
match_max 100000

expect "*?assword:*"

send -- "$password\r"
expect {
        "#*" {}
        "*>*" {}
        }
send -- "$command\r"
#send -- "\r"
send -- "exit\r"
expect eof

This works great unless I put stuff in speech marks or when I need to run multiple commands, e.g the following wont work:

autossh 123.123.123.123 root password ls -al && cd / && ls -al

It gives me the contents of ~ on my made up 123 host, then exits and gives me the contents of / on my local machine. If I do the same thing with speech marks I get the following error:

Code:

root@hostname # {ls -al && cd / && ls -al}
exit
{ls: not found

Ideally I'd like to be execute either of the above commands properly. Can anyone help.

Thanks

Well I am no expect guru, but how are {} considered speech marks?

Sorry, that was an example of the error: Exact input and output below:

Code:

[root@localhost scripts]# autossh 123.123.123.123 root password "ls -al && cd / && ls -al"
spawn ssh root@123.123.123.123
Password:
root@hostname # {ls -al && cd / && ls -al}
exit
{ls: not found
root@hostname # Connection to 123.123.123.123 closed.

It's cool, I've just got it working

Did this:

#set command [lrange $argv 3 11]
set command [lindex $argv 3]<--- Use this instead.
