It would definitely help if you provided a more detailed description of what you're trying to achieve with the sample data files and the expected output.
Hello,
A script has been written to extract a specific column data from a text file ONLY if the user's initial input matches the the data of the first column in the text, then only the data from that row will be prinited.
The problem I am having is that the code is only reading the records... (6 Replies)

Running solaris 9, on issuing the follwing command

Hi All,
I am looking to filter out filesystems which are greter than a specific value.
I use the command
df -h | awk '$4 >=70.00 {print $4,$5}'
But this results out as below, which also gives for lower values.

8% /u01/data

I was wondering whether anyone has any idea what is happening here. I'm using simple code to compare 2 tab delimited files based on column 1 values. If the column1 value of file1 exists in file2, then I'm to print the column4 value in file2 in column3 of file1. Here is my code:

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.
