# A simple variable example

myvariable=Hello

anothervar=Fred

echo $myvariable $anothervar
echo

sampledir=/etc

ls $sampledir

# Lines 4 and 6 - set the value of the two variables myvariable and anothervar.
# Line 8 - run the command echo to check the variables have been set as intended.
# Line 9 - run the command echo this time with no arguments. This is a good way to get a blank line on the screen to help space things out.
# Line 11 - set another variable, this time as the path to a particular directory.
# Line 13 - run the command ls substituting the value of the variable sampledir as its first command line argument.
