ksh(1) (MLX Addendum)              (MLX)              ksh(1) (MLX Addendum)

NAME
     ksh, rksh - KornShell, a standard/restricted command and programming
     language (MLX addendum)

SYNOPSIS
     ksh [ +aefhikmnprstuvx ] [ +o option ] ... [ -c string ] [ arg ... ]
     rksh [ +aefhikmnprstuvx ] [ +o option ] ... [ -c string ] [ arg ... ]

DESCRIPTION
     (International Functions)

     ksh can process characters from supplementary code sets in addition to
     ASCII characters. Characters from supplementary code sets can be used
     in command arguments, names of variables, functions, and aliases, as
     values of variables and field separators, and in prompt strings, com-
     ments and pipes.

     Searches and pattern matching using metacharacters are performed in
     character units, not bytes. In particular:

     ?    Matches any character, including characters from supplementary
          code sets.

     *    Matches any string, including strings containing characters from
          supplementary code sets.

     [ ]  Matches any one character in the string enclosed by square brack-
          ets, or any one character with a code value within the range
          designated using a minus (-) sign. Literal characters and charac-
          ters specifying ranges may be selected from supplementary code
          sets. If the characters which denote the first and last character
          of a range are from different code sets, the range will only
          match one of these two characters.

     [! ] Matches any one character which does not match the pattern
          enclosed in the brackets. Once again, literal characters and
          characters specifying ranges may be selected from supplementary
          code sets.

     Shell scripts may also contain characters from supplementary code
     sets.
