* This function takes a command line string and a pointer to the minishell
|
|
* context, splits the line into arguments, and fills a t_cmd structure with
|
|
* the command path, argument vector, and argument count.
|
|
*
|
|
* @param line The input command line string to parse.
|
|
* @param minishell Pointer to the minishell context.
|
|
*
|
|
* @return t_cmd The parsed command structure containing the command path,
|
|
* argument vector, and argument count.
|
|
*
|
|
* @todo Manage double quote
|
|
*
|
|
* @note The string array cmd.argv must be freed after the command has been
|
|
* executed.
