Hi all,
I'm reading <advanced bash scripting> and there is a example to kill a background process in a limited time,as shown below:

Greetings,
Using linux based OS and KSH.
I m trying to make a simple script to parse some logs to show a count per hour on a specific alarm starting from midnight to the current hour.
So I format my "HOUR" variable to show the current time and so I can use it in the following bit of code.... (6 Replies)
Hi.
I use this command to get list of running process:
ps -ef|grep ICP|grep -v grep
But how do I set the terminal to show full command? It seems that it always truncated to 60 chars no matter what options I put.
e.g output

i've read somewhere a long time ago that there's a way to hide the workings of a script in sub functions so that when run, it doesn't show up in the process table.
is this really possible?
for instance, i need to run a command that has a password in it. and when that;s being run, it can be... (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.
