Indenting your code

This is probably a good time to talk about indenting. In the past (that is, 30+ years ago) everyone used a text editor with a mono-spaced font to write their code and so it was relatively easy to keep everything lined up with just a one space indent. Later, when people started using word processors with a variable pitched font, it became harder to see the indentation and so more spaces (or tabs) were used. My suggestion is to use what you feel most comfortable with. However, with that said you may have to learn to read and use whatever code style that is in place for your company.

So far we have only talked about the while statement. Now let's look at an until loop in the next section:

Chapter 3 - Script 6

#!/bin/sh

x=1
while [ $x -lt 11 ]          # perform the loop while the condition 
do                           # is true
 echo "x: $x"
 let x++
done

echo "This shows the until loop...
