Don,
Your observation is fantastic. You are right, my files are actually having K, M, G and T no B is included. To avoid confusion I put B for K alone.
Actually, if you look at the 2nd, 3rd, and 4th lines in your sample input:
you'll see that you use both MB and M (not just M) and KB and K (not just KB) but all of the code samples you have been supplied allow any of your multipliers to be specified with or without a trailing B. As long as we have a good sample of the input and desired output, you can write code that adjusts to what it finds.

how would you calculate percentage by per line? Given a column of 16 lines, grab each line and divide it by the sum of the entire column and multiply by 100?

i have 3 files like
total.dat=18
equal.dat=14
notequal.dat=16
i need find the equal percentange means:
equalpercentage = ($equal.dat / $total.dat * 100)
How i can do this ?

Hi,
I have two variable and I need to calculate the percentage of them.

How can I do it? I need to do it till 2 decimal point. (16 Replies)
i am trying to get percentage : but not able to do it:

Hi,
I am looking for generic commands / scripts that could run across platforms especially on HP Itanium boxes to give me % of free OS parameters

Hello,
Ive got a bunch of numbers here e.g:
6065
6094
6348
6297
6161

How do I find out if there is a difference between 10% or more between one of these numbers ? I am trying to do this in Bash.. but no luck so far.. Does anyone have an Idea ??
Thanx,

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.
