A BASH shell has several variables in memory at any one time. Recall that a variable is simply a reserved portion of memory containing information that might be accessed. Most variables in the shell are referred to as environment variables because they are typically set by the system and contain information that the system and programs access regularly. Users can also create their own custom variables. These variables are called user-defined variables. In addition to these two types of variables, special variables are available that are useful when executing commands and creating new files and directories.
