Once the GetLine() function gets your input, it attempts to split any command with the semicolon between them, like:
Any command that starts with either a space or a hashtag will be ignored as a comment, like: (Notice the extra space in the first comment)
The first word is a command, and all words following it in a single command text are the series of arguments. These words then get split to arguments (without the switch indicator -switch) and switches (arguments that come after the dash) using the ProvidedArgumentsInfo class, though it does much more than that.
This class contains these variables:
Command: Target command
ArgumentsText: Provided arguments and switches
ArgumentsList: Array of arguments without the switches
SwitchesList: Array of switches
RequiredArgumentsProvided: Checks to see if the arguments are provided or not
RequiredSwitchesProvided: Checks to see if the required switches are provided or not
RequiredSwitchArgumentsProvided: Checks to see if the required switch arguments are provided or not
After the above class constructor is called, the shell attempts to execute an alias command, if found. Else, the built-in command is going to be executed.
Finally, the command executor thread is fired up with the ExecuteCommandParameters instance to hold command execution parameters for the same thread. The thread is then started.
You can know more about switch management by clicking on the below button:
Command SwitchesIf a command, such as wrap, is set to use the arguments string, you can escape special characters, as long as these characters are known. For example, if you want to pass a switch to a wrapped command, you can use the wrap command like this:
