MacのSpotlightを使えば、単に名前が一致するファイルやフォルダやアプリケーションなどが検索できるほか、中身が一致するものもあわせて検索できてとても便利です。普通画面右上の虫眼鏡アイコンをクリックして実行しますが、mdfind というコマンドを使えばコマンドラインから実行することもできるみたいです。

mdfind(1)                 BSD General Commands Manual                mdfind(1)

     mdfind -- finds files matching a given query

     mdfind [-live] [-count] [-onlyin directory] [-name fileName] query

     The mdfind command consults the central metadata store and returns a list of files that match
     the given metadata query. The query can be a string or a query expression.

     The following options are available:

     -0          Prints an ASCII NUL character after each result path.  This is useful when used in
                 conjunction with xargs -0.

     -live       Causes the mdfind command to provide live-updates to the number of files matching
                 the query.  When an update causes the query results to change the number of
                 matches is updated.  The find can be cancelled by typing ctrl-C.

     -count      Causes the mdfind command to output the total number of matches, instead of the
                 path to the matching items.

     -onlyin dir
                 Limit the scope of the search to the directory specified.

     -name fileName
                 Searches for matching file names only.

     -literal    Force the provided query string to be taken as a literal query string, without

     -interpret  Force the provided query string to be interpreted as if the user had typed the
                 string into the Spotlight menu.  For example, the string "search" would produce
                 the following query string:
                       (* = search* cdw || kMDItemTextContent = search* cdw)
