Hi,
i would like substitute the words containing the character "-" by any other.
i've already tried the tr command: tr '\-' 'X', for example.
But, this command doesn't work. It gave this:
Original text:
-i abcd-fe
Result text:
Xi abcdXfe
Result desired:
-i abcdXfe
Thanks! ;) (3 Replies)

rd-bomb
XScreenSaver(1) General Commands Manual XScreenSaver(1)
NAME
rd-bomb - reaction/diffusion textures
SYNOPSIS
rd-bomb [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-install] [-visual visual] [-width n]
[-height n] [-reaction n] [-diffusion n] [-size f] [-speed f] [-delay usecs]
DESCRIPTION
The rd-bomb program draws reaction/diffusion textures. The code is derived from the 'd' mode of the "bomb" visual musical instrument (see
http://www.cs.cmu.edu/~spot/bomb.html). I got the equations from xmorphia (http://www.ccsf.caltech.edu/ismap/image.html), which is based
on a version of the Gray-Scott model taken from:
John E. Pearson "Complex Patterns in a Simple System"
Science, 261,189, 9 July 1993.
If the frame-rate is too low, consider decreasing the width and height of the tile, or decreasing the size of the active part of the
screen.
OPTIONS
If one of the reaction, diffusion, radius, and palette options is set to a negative value, then that option will be set to a random appro-
priate value.
Be sure to try "-speed 1 -size 0.1 -epoch 3000".
rd-bomb 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.
-width n
-height n
Specify the size of the tile, in pixels.
-reaction n
-diffusion n
These are constants in the equations that effect its visual nature. Each may be one of 0, 1, or 2.
-radius n
Size of the seed.
-palette n
Selects a palette. Must be between 0 and 80, inclusive.
-size f What fraction of the window is actively drawn, a floating point number between 0 (exclusive) and 1 (inclusive). Default is 0.66.
-speed f
When a fraction of the screen is active, the active area moves at this rate (a floating point number). Default is zero. Suggested
value: 1.0.
-delay usecs
How many microseconds to delay between frames; default 1000, or about 1/1000th of a second.
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.
