Sort large file

I was wondering how sort works. Does file size and time to sort increase geometrically? I have a 5.3 billion line file I'd like to use with sort -u I'm wondering if that'll take forever because of a geometric expansion? If it takes 100 hours that's fine but not 100 days. Thanks so much. (2 Replies)

NAME
netris-sample-robot - sample robot for netris SYNOPSIS
netris-sample-robot [-l] DESCRIPTION
The netris-sample-robot is a sample implementation of the robot protocol. It plays quite well but isn't too hard to beat. The robot should be started from netris with the option -r to connect or wait for another player to join. You can also let two robots play against each other in that way, if you like. OPTIONS
-l Writes some log information into the file log in the current working directory. If it can't it bails out. EXAMPLES
To start the netris-sample-robot waiting for another connection with logfile use the following line: netris -w -r 'netris-sample-robot -l' You then just have to start netris somewhere else which connects to that robot. SEE ALSO
netris(6) BUGS
One known bug of the netris-sample-robot is that it hangs quite often. This was already filed as a bugreport against the package so please refrain from doing so again. If you have an idea why this happens or know a solution how to fix it feel free to mail us. AUTHORS
Netris was written by Mark H. Weaver <mhw@netris.org>. This manual page was written by Gerfried Fuchs <alfie@debian.org> for the Debian GNU/Linux system (but may be used by others). 0.5 16 Feb 2002 netris-sample-robot(6)
