Hi,

Again a little problem.
Do not understand good why an empty string is not detected.
Here is the program:

#!/bin/ksh

APR=`date | grep Apr | awk '{print $2$3}'`
MAY=`date | grep May | awk '{print $2$3}'`
JUN=`date | grep Jun | awk '{print $2$3}'`

echo "Variable Apr has value: $APR"
echo "Variable May has value: $MAY"
echo "Variable Jun has value: $JUN"
echo

for ITEM in $APR $MAY $JUN
do
if [[ "${ITEM}" = "" ]]
then
echo "The checked item has no value."
else
echo "The checked item has value ${ITEM}"
fi
done

Output:

Variable Apr has value:
Variable May has value:
Variable Jun has value: Jun17

The checked item has value Jun17

I expected it a little different.
Maybe this is an issue:

# echo $MAY | od -c
0000000 \n
0000001

Thanks in advance,
