writing a service...

jsheffie · 02-21-2006, 01:32 PM

Hi, I am wanting to write a script to run as a service in the background.

Is there anything special that has to be placed in the script to cause it to continuously run?

for example. send one ping packet once a minute forever.

I am using Bash shell scripting

thanks,

Something that simple could be run as a cronjob. Just create your script, make it executable and then crontab -e and add a line to execute the script every minute.

I'm sure there's a more elegant way, but I'm too newbie...

Are you asking how to write a daemon or how to write a script to ping something once per minute?

If the former, there's a decent HowTo that should be enough to get you started: http://www.linuxprofilm.com/articles...mon-howto.html

if the latter:

Code:

$ ping -i60 ADDRESS

There is a tool called "daemon" that can help you setup your script to run as a service. (lookup "libslack and daemon" on google).

Yep, that's what I would do. Then the ping would run after you logout, as long as the machine isn't turned off.

Peace...
