Shell Programming and Scripting

I know. Try the solution. It will work.
function pass_or_fail
{
# at this point the pass_or_fail function does not know any value for i
# but the 1st parameter passed to it is available as $1
# to get that in a variable called i I must do:
i=$1
# Wow , now i has a value!

if [ -s fail/${df[$i]} ]
then
echo " ${df[$i]} FAILED. Please check logs"

elif [ -s pass/${df[$i]} ]
then
echo " ${df[$i]} PASSED."
fi
}

Try that.

oh my God it works!

trx data loading :

xml data loading :
