Hello,
i have again problem with regexp :-P
I need to match all lines that contain one word but not contain
another.
Like to do "grep one | grep -v two:"
The syntax of the string is:
(any printable char)two:(any printable char)one(any printable char)
Example:
Apr 30 00:00:09 v890neg0 two: [ID 702911 daemon.one] findings:
blablabla
I tried with:
.*[^t][^w][^o].*one.*
but is not working, the string is always match and in other tries
using "less logic" i get always some different match :-(
P.S: i can't have more re.search, so i just need ONE regexp
The P.S: suggests homework, but this can't be homework because python regex won't do this, so your teacher gets an F if its homework. You require a negative look-behind assertion of variable length--not possible in python regex. You will have to use something else--or maybe you don't understand the homework problem.
