Email script

philosophia · 05-02-2008, 12:01 PM

Code:

#!/bin/bash
echo "test" | mail -s testsubject user@domain.com

I have a little one liner script that sends an email message - what's the best way to set it up so that this script sends mail for about 2 hours? wrap the mail line in a large for loop?

I may want to also vary the rate of sending. Any ideas?

You could use cron to schedule the script to run.

problem with using crontab is that you can only set it to send every minute - I'd probably need to send faster than that for my testing.

You could use the date command:
date +%s returns the amount of seconds since the Epoch. So you can just get the value of your start time and if you want to go for 2 hours you just keep checking the date +%s until it equals your start time plus (2*3600sec/hr).

A loop should work. If you want to vary the rate you could choose two signals for rate up / rate down and use 'trap' to catch them.

a loop of 1 to a really large number? or a loop that checks the date?
