tlimit=$(bc <<< $maxlimit*0.8)
echo 'Treshold limit at 80% ' $tlimit
a=$(lsof | wc -l)
echo 'Current usage ' $a
if [ $(bc <<< "$a > $tlimit") -eq 1 ]
then

In the above script, the output is to send a mail to the corresponding Mail ID .

When I run it manually it sends the mail.

But, when it is scheduled in cron, the mail is not being sent.

I cant understand what the problem is. How could I debug it?
