how to export value from function to rest of script

[dwcasey]

I have the following function in a script:
createBackupDir()
{
echo "Type the directory name to create"
read NEWDIR
if [[ -a $MILEAGEHOME/$NEWDIR ]]; then
echo "Directory $NEWDIR exists, try again"
else
mkdir $MILEAGEHOME/$NEWDIR
echo "Created directory $NEWDIR"
fi
read key'?Press Enter to continue ...'
}

How can I export the $NEWDIR variable from this function to the rest of the script so that it can be used after the directory is created?

Nothing to do.
You can use the NEWDIR variable in the rest of the script.
If you doesn't declare variable explicitely as local in a function, the variable is global to the script.
