NAME

       parsort - Sort (big files) in parallel

SYNOPSIS

       parsort options for sort

DESCRIPTION

       parsort uses GNU sort to sort in parallel. It works just like sort but faster on inputs
       with more than 1 M lines, if you have a multicore machine.

       Hopefully these ideas will make it into GNU sort in the future.

EXAMPLE

       Sort files:

         parsort *.txt > sorted.txt

       Sort stdin (standard input) numerically:

         cat numbers | parsort -n > sorted.txt

PERFORMANCE

       parsort is faster on a file than on stdin (standard input), because different parts of a
       file can be read in parallel.

       On a 48 core machine you should see a speedup of 3x over sort.
