# Environment variable names may only contain alpha-numeric characters (a-z,
|
|
# A-Z, 0-9) and underscores (_), and are prefixed with $. For example,
|
|
# specifying "$HOME/file.ext" would typically result in something like
|
|
# "/home/user/file.ext". To specify an actual "$" character, use "$$".
