I need to pass two arguments to expect, first one is the command to execute, the second one is the password.
here's my expect.sh
#!/usr/bin/expect spawn [lrange $argv 0 0] expect "password:" send [lindex $argv 1] interact
main script:
./expect.sh "ssh root@$SERVER1" $SERVER1_PASS
error:
couldn't execute "{ssh [email protected]}": no such file or directory
while executing
"spawn [lrange $argv 0 0]"
(file "./expect.sh" line 2)
why?
As far as I can tell, spawn's first argument needs to be a string, not a list of string.
And trying to pass a multi-word command line as a single string is going to cause problems. I think you'd have to split on spaces before calling spawn, and that's going to break if one argument contains a space. Maybe it's better to specify the password as the first argument, and the command as the rest of the arguments.
So try something like:
#!/usr/bin/expect
spawn [lindex $argv 1] [lrange $argv 2 end]
expect "password:"
send [lindex $argv 0]
interact
But then even that doesn't work.
According to Re: expect - spawn fails with argument list on comp.lang.tcl (Google Groups version), we have to call eval to split the list.
So the answer should be:
#!/usr/bin/expect
eval spawn [lrange $argv 1 end]
expect "password:"
send [lindex $argv 0]
interact
Finally, you need to be sending Enter after the password, so you want:
#!/usr/bin/expect
eval spawn [lrange $argv 1 end]
expect "password:"
send [lindex $argv 0]
send '\r'
interact
And then switch the order and don't quote the command when calling it:
./expect.sh "$SERVER1_PASS" ssh root@$SERVER1
But others have already done this. We don't need to re-invent the wheel.
See e.g. expect ssh login script
I found the shell scripts quite disturbing as far as scp was concerned. I decided to use php script for it, in crontab.
Php has a function
$conn = ssh2_connect($scpServer, 22);
then call
ssh2_auth_password($conn, $scpUser, $scpPassword);
ssh2_scp_send($conn, $scpLocalPath, $scpRemotePath);
OR
ssh2_scp_recv($conn, $scpRemotePath, $scpLocalPath);
And u are done.
Of course you'll need to define the variables of user, password, and the rest
Though I advise you to create a linux user just for this purpose of scp.
In order to install ssh2, try
