Would you mind changing my user name to match my Ubuntu One name, ie 'Owen Z5'?
This question might easy, I am new to natural language processing. I have million lines like the example below. I want to replace the last match in a line with another.
My problem is like this
user,user,' i got the sims 3'
user,user,' cheer up liz'
user,user,' you ok mate?
When I attempt to perform certain actions within ubuntu I am asked to authenticate with a root user, but ubuntu doesn't give me options for which root user, it just specifies it as the user that set up my machine.
