Shell Programming and Scripting

Use cron to run that script every n minutes from 10:00h till 17:00h. If you replace the second while loop with a mail command there won't be any terminal output (which cron would send per mail anyhow, so you could skip mailing in your script...)

Can u please replace the mail concept in while loop and please mention the cron entries in crontab.

I don't know How can I replace the mail concept in while loop and cron entries in crontab too.Please modify the shell script for mail concept in while loop and please mention the cron entries in crontab for 10.00 A.M to 5.00 P.M.Please give me a complete shell script for mail concept and cron entries too.

Actually I want to ping continuously and then I want to get a mail when the connection is lost.If Network cuts down in any 16 ip that time only I want to get a one mail ip is down.

Well, try this (untested!):

Code:

#!/bin/bash
UplistFilePath="/root/Uplist.txt"
DownlistFilePath="/root/Downlist.txt"
rm -rf $UplistFilePath
rm -rf $DownlistFilePath

while IFS="\t" read   $ip $branchname $branchcode
        do      ping -c 1 -W 1 $ip > /dev/null && { RES=up; FN=$UplistFilePath; } || { RES=down; FN=$DownlistFilePath; }
                printf "%s %s of IPaddress %s is %s.", $branchcode, $branchname, $ip, $RES > "$FN"
        done < IPfile.txt
[ -s "$DownlistFilePath" ] &&  cat "$DownlistFilePath"

use a crontab entry like

Code:

MAILTO=upload.XXX@example.com
*/5 10-17 * * 1-5 yourpath/yourscript

Your crontab may need a different syntax, though. And, all of this is not tested, so please read man pages and try to eradicate errors yourself...
