That's a useless use of ls *. for file in `ls *` , when it works at all, has the same effect as for file in * .

for file in TT*
do
        exec 5<"$file" # Open the file
        read G MAILBOXNUM <&5
        read G FILENAME <&5
        read G FILELOCATION <&5
        read G FILETYPE <&5
        exec 5<&- # Close the file

        echo "Do something to ${FILELOCATION}/${FILENAME}.${FILETYPE}"
done
