Elements of shell
Vue translates exported shell variables (specified by the $ prefix) and positional parameters
into their real values during the initial phase of compilation. So, $1, $2, and so on, will be
replaced with corresponding value by ProbeVue.
When assigning general environment variables to a string, you need to make sure it starts
and ends with a backward (\) slashmark. For instance, the environment variable
“VAR=abcdef” will result in an error when assigned to a string. Defining it as “VAR=\”abcdef\””
is the proper way of using it in a Vue script.
Restriction: The special shell parameters like $$, $@, and so on are not supported in
Vue. However, they can be obtained by other predefined built-in variables.
Example 3-41 illustrates the use of various variable types, and also uses kernel variables.
The comments provided in the Vue script explain the scope of various variables.
