DESCRIPTION
     This document describes the regular expressions (or globbing
     patterns) used in filename globbing with scp2 and sftp2 .


PATTERNS
     The escape character is a backslash '\'. With this  you  can
     escape  meta  characters  which  you'd  like to use in their
     plain character form.

     In the following examples literal `E'  and  `F'  denote  any
     expression, be it a pattern or character etc.

     *    Match any string consisting of zero or more characters.
          The characters can be any characters apart from slashes
          (/). However, the asterisk does not match a  string  if
          the  string  contains a dot (.) as its first character,
          or if the string contains a  dot  immediately  after  a
          slash.  This  means that the asterisk cannot be used to
          match filenames that have a dot as their first  charac-
          ter.

          if the previous character is a slash (/), or the aster-
          isk (*) is used to denote a match at the beginning of a
          string, it does match a dot (.).

          That is, the `*' functions as is normal in  UNIX  shell
          fileglobs.

     ?    Match any single character except for a slash (/). How-
          ever,  do  not match a dot (.) if located at the begin-
          ning of the string, or if the previous character  is  a
          slash (/).

          That is, `?' functions  as  is  normal  in  UNIX  shell
          fileglobs  (at  least  ZSH, although discarding the dot
          may not be a standard procedure).

     **/  match any sequence of characters that is either  empty,
          or  ends in a slash. However, the substring `/.' is not
          allowed. This mimics ZSH's **/ construct. (Please  note
          that `**' is equivalent to `*'.)

     E#   Act as Kleene star, match E zero or more times.

     E##  Closure, match E one or more times.

     (    Start a capturing subexpression.

     )    End a capturing subexpression.

     E|F  Disjunction, match (inclusively) either E or  F.  E  is
          preferred if both match.

     [    Start a character set. (see below)


CHARACTER SETS
     A character set starts with ``['' and  ends  at  non-escaped
     ``]''  that  is  not part of a POSIX character set specifier
     and that does not follow immediately after ``[''.

     The following characters have a special meaning and need  to
     be escaped if meant literally:


     - (minus sign)
          A range operator, except immediately after ``['', where
          it loses its special meaning.

     ^ or !
          If immediately after the starting ``['', denotes a com-
          plement:  the whole character set will be complemented.
          Otherwise literal.  ``^''.

     [:alnum:]
          Characters  for  which  `isalnum'  returns  true   (see
          ctype.h).

     [:alpha:]
          Characters  for  which  `isalpha'  returns  true   (see
          ctype.h).

     [:cntrl:]
          Characters  for  which  `iscntrl'  returns  true   (see
          ctype.h).

     [:digit:]
          Characters  for  which  `isdigit'  returns  true   (see
          ctype.h).

     [:graph:]
          Characters  for  which  `isgraph'  returns  true   (see
          ctype.h).

     [:lower:]
          Characters  for  which  `islower'  returns  true   (see
          ctype.h).

     [:print:]
          Characters  for  which  `isprint'  returns  true   (see
          ctype.h).

     [:punct:]
          Characters  for  which  `ispunct'  returns  true   (see
          ctype.h).

     [:space:]
          Characters  for  which  `isspace'  returns  true   (see
          ctype.h).

     [:upper:]
          Characters  for  which  `isupper'  returns  true   (see
          ctype.h).

     [:xdigit:]
          Characters  for  which  `isxdigit'  returns  true  (see
          ctype.h).


     EXAMPLE
          [[:xdigit:]XY]    is    typically     equivalent     to
          [0123456789ABCDEFabcdefXY] .
