Does anyone know how I can use gzip to zip a large log file on the fly.
My simulation is currently logging a large file that I need for analysis at a later point. However the files are so huge that I may even run out of disk space. The content is mainly text so when compressed the files are... (2 Replies)
Hi,
as part of a script i have a loop that goes though a set of files.
This loop can take some time, so i'd like to show the user that something is happening by showing them the filename being worked on.
I could create a long list of file names in the terminal using echo or print... (0 Replies)
I want to split big files based on a pattern to stdout.
Although csplit works well for me splitting the output into separate files (e.g. xx00, xx01, xx02, ...), the following is not working as expected:

csplit bigfile '%pattern%'... (2 Replies)
Can somebody explain to me why the diff output is not going to stderr?
Yet when I issue a diff from the command line the return code is -ne 1.
I am guessing diff always writes to stdout???
Is there away I can force the difff to write to stderr USING THE CURRENT

Hi
Is there way to, say, echo a line and make sure it is always displayed on the first line, no matter what is coming out on stdout?
eg:
#!/bin/bash

echo " ...... Internal audit script ......"
tar xvf hugefile.tar
I'd like to have the " Internal audit script " line to be shown... (2 Replies)
Hi,
I have a program set to read in a text file, change certain characters and then print the altered version to the screen but does anyone know how to save the new version as another text file? And, if possible, how to specify the file name, and perhaps location?
Thanks! (2 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.
