max=`cut -d ' ' -f1 numbers`

min=`cut -d ' ' -f1 numbers`

for num in `cat numbers`

do

        if [ $num -gt $max ]

        then

                max=$num

        fi

done

for num in `cat numbers`

do

        if [ $num -lt $min ]

        then

                min=$num

        fi

echo "The max elements is $max"

echo "The min element is $min"

Output:

[141740@localhost ~]$ cat numbers

10 20 30 40 50

[141740@localhost ~]$ sh minmax.sh

The max elements is 50

The min element is 10
