Python pexpect & pxssh with sudo and EOF
I am doing ssh login using this script:
import pxssh
import pexpect
s = pxssh.pxssh()
hostname = 'localhost'
username = 'py_worker'
password = 'nicejob'
s.login (hostname, username, password)
print "logged in"
Then I want to run some program which in some cases may require a sudo password and in some cases may not be required. So I want to create a script that can provide the sudo password when needed and just run the program if sudo is not given. I thought this code could handle:
s.sendline('sudo apt-get check')
i=s.expect(['password', pexpect.EOF])
if i==0:
print "I give password"
s.sendline("nicejob")
s.prompt()
elif i==1:
print "EOF cought"
s.prompt()
print s.before
Can anyone help with lines of code that sudo might handle correctly?

thanks for asking, it helped me.
you will probably need to spell out the exceptions and re for rootprompt, but here you go.
def sudo(s,password):
rootprompt = re.compile('.*[$#]')
s.sendline('sudo -s')
i = s.expect([rootprompt,'assword.*: '])
if i==0:
print "didnt need password!"
pass
elif i==1:
print "sending password"
s.sendline(password)
j = s.expect([rootprompt,'Sorry, try again'])
if j == 0:
pass
elif j == 1:
raise Exception("bad password")
else:
raise Exception("unexpected output")
s.set_unique_promp
