awk understands tokens, which lets you do things on 'the third column' instead of a big regex with width specifiers, so I'd use it here to make things simpler.
Thanks for the all the help last evening on CRON jobs. It's now working.
Is it possible with cron to save a backup of a file to a different server or location? The idea being that if one host goes arse over tit, I'll have a backup of the DB on another server?
Many thanks,

I am writing a script that will be placed in a crontab, which basically retrieves a file that is overwritten everyday (with current customer data) and then sent to another company.

Im having a problem with my ftp CRON jobs. I have another related (but not the same question in shell scripting).

to show that every part of the script have been executed. A cron job
executes this script and when is completed the output is sent by email.

I wrote a quick little script that will eventually end up as a cron job to export rrd files for my cacti server.
Here is the script:
#!/bin/bash
rm -rf /backup/cacti_xml/*
cd /var/www/html/rra
ls -1 *.rrd | awk '{print "rrdtool dump "$1" > /backup/cacti_xml/"$1".xml"}' | sh -x
Is there... (5 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.
