It looks to me that your expr syntax error has to do with non-numeric data. I don't know what perl program $EpochSh does, but if it doesn't print out a number followed by a colon, you will have trouble with this line:

export Eval=`$EpochSh $Epoch | cut -d ':' -f 2`

Could that be your problem?

Also, I would like to gently point out your Useless Use Of Cat (UUOC). If you use a while loop, you can let it do your parsing for $User, $Epoch, and $Maxday:

Code:

#!/bin/ksh
while IFS=":" read User f2 Epoch f4 Maxday therest
do
echo "User: $User"
echo "Epoch: $Epoch"
echo "Maxday: $Maxday"
done < /etc/shadow

Also, if /etc/shadow's lines contained spaces, your code would fail miserably.

Another point: ksh/bash type shells let you do arithmetic, so you don't have to use expr:

Code:

if [[ $Eval == $(($x - 3)) ]]
then
echo "equal"
else
echo "NOT equal"
fi
