I'm trying to instruct my Python installation to execute an Expect script "myexpect.sh":
#!/usr/bin/expect
spawn ssh usr@myip
expect "password:"
send "mypassword\n";
send "./mycommand1\r"
send "./mycommand2\r"
interact
I'm on Windows so re-writing the lines in the Expect script into Python are not an option. Any suggestions? Is there anything that can run it the way "./myexpect.sh" does from a bash shell?
I have had some success with the subprocess command:
subprocess.call("myexpect.sh", shell=True)
I receive the error:
myexpect.sh is not a valid Win32 application.
How do I get around this?
Use the pexpect library. This is the Python version for Expect functionality.
Example:
child = pexpect.spawn('Some command that requires password')
child.expect('Enter password:')
child.sendline('password')
child.expect(pexpect.EOF, timeout=None)
cmd_show_data = child.before
cmd_output = cmd_show_data.split('\r\n')
for data in cmd_output:
print data
Pexpect comes with lots of examples to learn from. For use of interact(), check out script.py
from examples:
(For Windows, there is an alternative to pexpect.)
