Hi Wisecracker, I must say that was a wonderful catch.

Code:
$ vi prog11.sh
"prog11.sh" 23 lines, 639 characters
echo "Enter file name"
read FILENAME=$1
linecount=0
charcount=0
n=0
linecount=`wc -l $FILENAME | cut -d " " -f7`
if [ $linecount -ge 0 ]; then
        while [ $nu -ne $linecount ]
                do
                nu=`expr $nu + 1`
                line=`sed -n ''$nu'p' $FILENAME`
                charcount=`echo $line | wc -c`
if [ "$charcount" > "20" ] && [ "$charcount" < "25" ]
then
                                        echo "Line with length between 20 and 25"
                                        echo $charcount $line
                        fi
                done
else
        echo "Error: no lines in the file"
        exit 1
fi
