where in the file system to start looking at files?
Starting from the top level of your hard drive could take a long time, so let's just look in your home directory.
ホームディレクトリの下で開始します.
Luckily, Unix (and OS X) has a shorthand character for the home directory, which is ~ (also known as the tilde).
Unixとosxには、ホームディレクトリを表す簡単な文字列があります.
