Variables

Variables are used to store values.

A variable consists in:

• a name that uniquely identifies the variable,

• and an associated value

Variable Reference

Variables can be referenced inside expansion text or command parameters using the following syntax:

$(name)

When an expansion is produced, a variable name reference is replaced by the corresponding variable value.
