Without conditional statements, your script will only follow a fixed process. Intereacting with the user would be almost of no use. Let's see how we can input them!
Introduction[]
We have used a conditional statement before (in all scripts, actually):
if [ "$PLAYONLINUX" = "" ]
then
exit 0
fi
If the condition is true, the code between then and fi will be executed.
Syntax[]
The condition is put in square brackets. The code to be executed if the condition is true is put between then and fi.
Note: Do not run this code.
if [ condition ] then code fi
