Hi ,

I have a script wherein i have a For Loop.
Within this for loop i create a variable and assign it a value.

The script goes to a For Loop only if certain conditions are met , which means the variable may or may not exists.

However down the line in the script i have to check if that variable exists on or not.

How do i check this

I tried this but the script fails with the following error "Specify a parameter with this command."
if [ -s ${FILE_LIST} ]
then
echo "Variable Exist"
fi

Please help

Sam
