/**
 * Prints the current working directory.
 * 
 * This command displays the absolute path of the current working directory
 * stored in the shell context. It's equivalent to the Unix/Linux 'pwd' command
 * and provides the same functionality as 'cd' without arguments.
 * 
 * Usage:
 * - pwd : Print the current working directory path
 * 
 * The command always prints the absolute path of the current directory,
 * making it useful for scripts and when you need to know your exact location
 * in the file system.
