I want to start writing in shell script but dont know what to download
Hi everyone. I have been programming now for 2 days in college using shell script. I am nearly certain that is used in the linux operating system? would I be correct about that? anyway, what i want to do is practise writing in shell script at home to improve my skills and because i enjoy it. im using windows 7 so am i supposed to download linux in order for me to be even half way able to start programming? if so please explain how and then do i download something that looks like command prompt. sorry for being vague .. its hard to explain when i dont know what i will be doing. here is an example of what i was programming in college.
#program to read in two numbers and add them together
echo " enter your first number "
echo " enter your second number "
echo " $a + $b = $c "
THANKS TO ANYONE WHO HELPS.
