I want to find the top N entries for a certain field based on the values of another field.
For example if N=3, we want the 3 best values for each entry:
Entry1 ||| 100
Entry1 ||| 95
Entry1 ||| 30
Entry1 ||| 80
Entry1 ||| 50
Entry2 ||| 40
Entry2 ||| 20
Entry2 ||| 10
Entry2 ||| 50... (1 Reply)
So, I need to do some summing. I have an Apache log file with the following as a typical line:
127.0.0.1 - frank "GET /apache_pb.gif HTTP/1.0" 200 2326
Now, what I'd like to do is a per-minute sum. So, I can have awk tell me the individual minutes, preserving the dates(since this is a... (7 Replies)
Hi all,
Sorry the title is a mess, but did not find a better description at the time.
So here is my problem:
I have an input file:

Hi,

00:09:01.221 5678
00:12:23.321 93444
The file has more line than this but i just wanted to put in a snippet to ask how I would get the highest number with time stamp into another file. So from the above... (2 Replies)
Hi,
I have two files, one of which I would like to sort based on the order of the data in the second. I would like to do this using a simple unix statement.
My two files as follows:
File 1:
12345 1 2 2 2 0 0
12349 0 0 2 2 1 2
12350 1 2 1 2 2 2

File2:

the below is sorted as it is. the fields that i'm interested in are the 4th and 5th field.
i want to sort the based on the 4th field.
my past attempt to do this was to do something like this:
awk '{print $4}'| awk '{print $1":"$2}' datafile | sort | uniq
however, if i do that, i lose... (2 Replies)
In the tab-delimeted input file below I am trying to use awk to update the value in $2 if TYPE=ins in bold, by adding the value of
HRUN= in italics. In the below since in line 1 TYPE=ins the 117282541 value in $2 has 6 added because that is the value of HRUN=.
Hopefully the awk is a start but I... (2 Replies)
I am trying to output a tab-delimited result that uses the data from a tab-delimited file to combine and subtract specific lines.
If $4 matches in each line then the first matching sequential $6 value is added to $2, unless the value is 1, then the original $2 is used (like in the case of line... (3 Replies)
Hi,
So awk is driving me crazy on this one. I have searched everywhere and read man, docs and every related post Google can find and still no luck. The actual files I need to run this on are sensitive in nature, but it is the same thing as if I needed to calculate weighted grades for multiple... (15 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.
