Shell Scrips? 70s? NOT AT ALL!!!

Hi,

I found some very useful shell scripts at bashscripts.org. You may use them too... take a look.

A very small (10000 lines?) script... check it.

#!/bin/bash

#######################################################
#     Bash CALCulator 2

#    FILE: bashcalc2.sh

header ()
{
clear; echo "Bash Calculator - Enter a calculation and hit enter";
echo "---------------------------------------------------";
}

calc ()
{
header
while true
do read -p "" bashcalc;
    if [ "$bashcalc" = "quit" ]
      then
        exit
    fi

    if [ "$bashcalc" = "clear" ]
     then
       calc
    fi

    if [ "$bashcalc" = "help" ]
     then
       clear
       echo "Options include:"
       echo " help - This help file"
       echo " clear - Clears the screen"
       echo " quit - Quits the program"
       echo " "
       read -p  "Hit any key to continue" temp;
       calc
    fi

echo "scale=4; ${bashcalc}" | bc ;
echo "---------------------";
done
}

# Program run starts here
calc

exit 0

I know you have python or perl but admit it, you always liked bash scripting, after all, this is our interpreter.
