I'm tryning to do something like this,
I have this file:
spaces12tabgoodbye
spaces3tabhello
I want to copy to another file the lines that have the number above 10...
I thought using sort -rn but I don't know how to discard the lines that have the number below 10.
Any idea?
Thanks (3 Replies)

Here is a script for automatic labeling of previously unlabeled disks.
Other methods exist (format -f cmd_file), but I like this because it's all in one place.

Hi, All,
I want to calculate a specific value of a Gaussian distribution, say the mean is a=3, variance is b=5, the indepentent variable is x=2, how could I get the y which is the Gaussian distribution value of x.
Thanks,

Say for example I have a list of numbers..
5
10
13
48
1
could I use grep to show only those numbers that are above 10? For various reasons I can only use grep... not awk or sed etc. (7 Replies)
friends that way I can validate that the value is numeric taken
instance
var = 12re
if var = numeric then a
echo "Numerical
else
echo "not mumerico"
fi

Greetings!
My first PHP question; and, no doubt, a "no-brainer" for the initiated :)
The question centers around the proper syntax for input field labeling. The snippet which puzzles me (and the candidate which I wish to modify) goes like this:<?php _e('Hello World'); ?>:<br />What I'd like... (0 Replies)

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
