[Tutor] Searching 2 Strings in A File

[dohoang4093 at comcast.net]

i am writing a python script that will be invoked as follows: 

myScript.py <an IP> 

and the script is as follwos: 

x = "Device " + sys.argv[1] + " restored the database" 
y = "Created connection to " + sys.argv[1] 

cmd_line = Popen(["egrep", "(x,y)", aLogFile], stdout=PIPE, stdin=PIPE, stderr=STDOUT) 

the above code does not work because it will look for x and y in aLogFile instead of 
looking for <"Device " + sys.argv[1] + " restored the database"> and <"Created connection to " + sys.argv[1]> 
Any hint is appreciated.
