Hey guys, so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.
My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2 numbers, etc., you'd get an error message. Any suggestions? Thanks in advance.
Edit: Here's what my script looks like so far:

Hi,

I'm a bit new to bash programming and I was assigned the job of writing a script that will check to see if a program server is running and to restart the program if it is not up. The script is supposed to check the program every hour (which I have looked up and I believe I know how to do) and send... (3 Replies)
hi guys
we've had nagios spewing false alarm (for the umpteenth time) and finally the customer had enough so they're starting to question nagios. we had the check interval increased from 5 minutes to 2 minutes, but that's just temporary solution. I'm thinking of implementing a script on the... (8 Replies)

Is there a quick way to check to see if a script is already running.
I want to put in a check in the script to exit, if already running.
Currerntly i can only think of doing it the following way.

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.
