This shell script shows how to accept command line arguments in shell scripts. In this example it accepts two numbers and calculates their average.avg=0 temp_total=0 number_of_args=$# # # First see the sufficent cmd args # if [ $# -lt 2 ] ; then echo -e "Opps! I need atleast 2 command line args\n" echo -e "Syntax: 0ドル: number1 number2 ... numberN\n" echo -e "Example:0ドル 5 4\n\t0ドル 56 66 34" exit 1 fi # # now calculate the average of numbers given on command line as cmd args # for i in $* do # addition of all the numbers on cmd args temp_total=`expr $temp_total + $i` done avg=`expr $temp_total / $number_of_args` echo "Average of all number is $avg"
