Many other systems also have an external sort utility, but the options and capabilities will differ. It is probably better to use the built-in Vim sort unless you are looking for a specific feature of the external sort (or using an old Vim without the <tt>:sort</tt> command). |

Vim has a very powerful built-in sort utility, or it can interface with an external one. In order to keep only unique lines in Vim, you would:
:{range}sort u

Numeric sort
