Smilie Thanks a lot, it's clearer and easier to read. You take a weight off my mind.
Which partly solves my problems as the badly formatted lines are reported once.
But I am facing a problem, I can not create an another function that processes only lines well formatted. I continue to look, but all suggestions are welcome.

Another thing
Can you explain the red tag in script ?


Code:
valid() {
        case "$3" in
        [0-5][0-9]) ;;
        #60) ;;
        *) return 1;
        ;;
        esac

        case "$2" in
        [0-1][0-9]) ;;
        2[0-3]) ;;
        *) return 1 ;;
        esac

        OLDIFS="$IFS"
        IFS="-"
                set -- $1 # $1=YYYY, $2=MM, $3=DD
        IFS="$OLDIFS"

        case "$1" in
        [0-9][0-9][0-9][0-9]) ;;
        *) return 1;
        esac

        case "$2" in
        0[1-9]) ;;
        1[0-2]) ;;
        *) return 1;;
        esac

        case "$3" in
        0[1-9]) ;;
        [1-2][0-9]) ;;
        3[0-1]) ;;
        *) return 1 ;;
        esac

        return 0
}

while read DATE HH MM
do
        [ "${DATE:0:1}" = "#" ] && continue # Ignore comments
        [ -z "$DATE" ] && continue # Ignore blank lines
        valid $DATE $HH $MM || echo "$DATE $HH $MM is invalid"
done < inputfile

I am facing a problem, I can not create a function that processes only lines well formatted. I continue to look, but all suggestions are welcome.
