Hello all,
Need to pick your brains,
I have a 10Gb file where each row is a name, I am expecting about 50 names in total. So there are a lot of repetitions in clusters.
So I want to do a
sort -u file
Will it be considerably faster or slower to use a uniq before piping it to sort... (3 Replies)

XScreenSaver(1) General Commands Manual XScreenSaver(1)NAME
glforestfire - draws a GL animation of sprinkling fire-like 3D triangles
SYNOPSIS
glforestfire [-display host:display.screen] [-window] [-root] [-visual visual] [-delay microseconds] [-count number_of_particles] [-trees
number_of_trees] [-size viewport_size] [-texture] [-no-texture] [-shadows] [-no-shadows] [-fog] [-no-fog] [-wireframe] [-no-wireframe]
[-wander] [-no-wander] [-trackmouse] [-no-trackmouse] [-fps] [-no-fps]
DESCRIPTION
The glforestfire program draws an animation of sprinkling fire-like 3D triangles in a landscape filled with trees.
OPTIONS
glforestfire accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
-fps Display a running tally of how many frames per second are being rendered. In conjunction with -delay 0, this can be a useful
benchmark of your GL performance.
-trees number_of_trees
Specify how much trees are drawn in the landscape.
-count number_of_particles
Specify how much fire particles are drawn. A very special case is 0 wich means that you get rain !
-size viewport_size
Viewport of GL scene is specified size if greater than 32 and less than screensize. Default value is 0, meaning full screensize.
-texture
Show a textured ground and the trees. This is the default.
-no-texture
Disables texturing the landscape. This implies that no trees are drawn.
-shadows
Show a shadow for each particle on the ground. This is the default.
-no-shadows
Disables the drawing of the shadows.
-fog Show a fog in the distance.
-no-fog Disables the fog. This is the default.
-wander Move the observer around the landscape. This is the default.
-no-wander
Keep the fire centered on the screen.
-trackmouse
Let the mouse be a joystick to change the view of the landscape. This implies -no-wander.
-no-trackmouse
Disables mouse tracking. This is the default.
-wire Draw a wireframe rendition of the fire: this will consist only of single-pixel lines for the triangles.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
