Script Executions

Scripts can be created by designating Ion as the interpreter in the shebang line.

#!/usr/bin/env ion

Then writing the script as you would write it in the prompt. When finished, you can execute the shell by providing the path of the script to Ion as the argument, along with any additional arguments that the script may want to parse. Arguments can be accessed from the @args array, where the first element in the array is the name of the script being executed.

#!/usr/bin/env ion

if test $len(@args) -eq 1
    echo "Script didn't receive enough arguments"
    exit
end

echo Arguments: @args[1..]

An example of calling a script with positional arguments

ion some_scirpt first second third

Content of some_scipt.

for next in @args
   # do something with the given arguments
   echo $next
end

Output: of example

Note: The zeroth argument is the name of the executed script.
