NAME

SYNOPSIS
       glob ?switches? pattern ?pattern ...?
_________________________________________________________________

DESCRIPTION
       This  command  performs  file name ``globbing'' in a fashion similar to
       the csh shell.  It returns a list of the files whose names match any of
       the pattern arguments.

       If  the initial arguments to glob start with - then they are treated as
       switches.  The following switches are currently supported:

       -nocomplain    Allows an empty  list  to  be  returned  without  error;
                      without  this  switch an error is returned if the result
                      list would be empty.

       --             Marks the end of switches.  The argument following  this
                      one  will be treated as a pattern even if it starts with
                      a -.

       The pattern arguments may contain any of the following special  charac-
       ters:

       ?         Matches any single character.

       *         Matches any sequence of zero or more characters.

       [chars]   Matches  any  single character in chars.  If chars contains a
                 sequence of the form a-b then any character between a  and  b
                 (inclusive) will match.

       \x        Matches the character x.

       {a,b,...} Matches any of the strings a, b, etc.

       As with csh, a  ``.'' at the beginning of a file's name or just after a
       ``/'' must be matched explicitly or with a {} construct.  In  addition,
       all ``/'' characters must be matched explicitly.

       If the first character in a pattern is ``~'' then it refers to the home
       directory for the user whose name follows the ``~''.  If the  ``~''  is
       followed  immediately  by  ``/'' then the value of the HOME environment
       variable is used.

       The glob command differs from csh globbing in two ways.  First, it does
       not  sort  its  result list (use the lsort command if you want the list
       sorted).  Second, glob only returns the names of  files  that  actually
       exist;  in csh no check for existence is made unless a pattern contains
       a ?, *, or [] construct.

PORTABILITY ISSUES
       Unlike other Tcl commands that will  accept  both  network  and  native
       style  names  (see  the filename manual entry for details on how native
       and network names are specified), the glob command only accepts  native
       names.   Also, for Windows UNC names, the servername and sharename com-
       ponents of the path may not contain ?, *, or [] constructs.
