I am trying to do some basic log parsing, and well, I am absolutely floored
at this seemingly simple problem. I am by no means a novice in python, but
yet this is really stumping me. I have extracted the pertinent code snippets
and modified them to function as a standalone script. Basically I am reading
a log file ( in this case, testlog.log) for entries and comparing them to
entries in a safe list (in this case, safelist.lst). I have spent numerous
hours doing this several ways and this is the most simple way I can come up
safelistfh = file('safelist.lst', 'r')
safelist = safelistfh.readlines()
logfh = file('testlog.log', 'r')
loglines = logfh.readlines()
for entry in safelist:
print 'I am searching for\n'
print 'to exist in\n'
comp = line.find(entry)
if comp <> -1:
out = 'Failed'
out = 'Passed'
for log in loglines:
finalentry = safecheck(log)
if finalentry == 'Failed':
print 'This is an internal site'
print 'This is an external site'
The contents of the two files are as follows:
It seems that no matter what I do, I can't get this to fail the " if comp <>
-1:" check. (My goal is for the check to fail so that I know this is just a
URL to a safe[internal] site)
My assumption is that the HTTP:// is somehow affecting the searching
capabilities of the string.find function. But I can't seem to locate any
documentation online that outlines restrictions when using special
