Conditional Statements

Bash has conditional statements just like any other programming language, and the most common is the if command. To see this work we're going to edit the script we made earlier to do a little check first. If you recall the script, it will always print '$age years old', but what if age is 1? You wouldn't say '1 years old'. To fix this we will use an if statement. Do nano

If Statement

Now the script will check to see if the user is 1, and if he or she is, print 'year' instead of 'years'.
