find: Regular Expressions

 
 8.5 Regular Expressions
 =======================
 
 The '-regex' and '-iregex' tests of 'find' allow matching by regular
 expression, as does the '--regex' option of 'locate'.
 
    Your locale configuration affects how regular expressions are
 interpreted.  ⇒Environment Variables, for a description of how
 your locale setup affects the interpretation of regular expressions.
 
    There are also several different types of regular expression, and
 these are interpreted differently.  Normally, the type of regular
 expression used by 'find' and 'locate' is almost identical to that used
 in GNU Emacs.  The single difference is that in 'find' and 'locate', a
 '.' will match a newline character.
 
    Both 'find' and 'locate' provide an option which allows selecting an
 alternative regular expression syntax; for 'find' this is the
 '-regextype' option, and for 'locate' this is the '--regextype' option.
 
    These options take a single argument, which indicates the specific
 regular expression syntax and behaviour that should be used.  This
 should be one of the following:
