NAME

       glob - Return names of files that match patterns

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:	   |

       -directory directory															   |
	      Search for files which match the given patterns starting in the given directory.	This allows searching of  directories  whose  name |
	      contains glob-sensitive characters without the need to quote such characters explicitly.	This option may not be used in conjunction |
	      with -path.															   |

       -join																	   |
	      The remaining pattern arguments are treated as a single pattern obtained by joining the arguments with directory separators.

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

       -path pathPrefix 															   |
	      Search for files with the given pathPrefix where the rest of the name matches the given patterns.  This allows searching	for  files |
	      with  names  similar to a given file even when the names contain glob-sensitive characters.  This option may not be used in conjunc- |
	      tion with -directory.														   |

       -types typeList																   |
	      Only list files or directories which match typeList, where the items in the list have two forms.	The first form is like	the  -type |
	      option  of  the  Unix  find  command: b (block special file), c (character special file), d (directory), f (plain file), l (symbolic |
	      link), p (named pipe), or s (socket), where multiple types may be specified in the list.	Glob will return all files which match	at |
	      least one of the types given.													   |

	      The  second  form specifies types where all the types given must match.  These are r, w, x as file permissions, and readonly, hidden |
	      as special permission cases.  On the Macintosh, MacOS types and creators are also supported, where any item which is four characters |
	      long  is assumed to be a MacOS type (e.g. TEXT).	Items which are of the form {macintosh type XXXX} or {macintosh creator XXXX} will |
	      match types or creators respectively.  Unrecognised types, or specifications of multiple MacOS types/creators will signal an error.  |

	      The two forms may be mixed, so -types {d f r w} will find all regular files OR directories that have both  read  AND  write  permis- |
	      sions.  The following are equivalent:												   |
			    glob -type d *													   |
			    glob */														   |
	      except that the first case doesn't return the trailing ``/'' and is more platform independent.					   |

       --     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 characters:

       ?	 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 (inclu-
		 sive) 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  addi-
       tion, 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.

       Windows
	      For  Windows  UNC names, the servername and sharename components of the path may not contain ?, *, or [] constructs.  On Windows NT,
	      if pattern is of the form ``~username@domain'' it refers to the home directory of the user whose account information resides on  the
	      specified  NT  domain  server.  Otherwise, user account information is obtained from the local computer.	On Windows 95 and 98, glob
	      accepts patterns like ``.../'' and ``..../'' for successively higher up parent directories.

       Macintosh
	      When using the options, -dir, -join or -path, glob assumes the directory separator for the entire pattern  is  the  standard  ``:''.
	      When not using these options, glob examines each pattern argument and uses ``/'' unless the pattern contains a ``:''.
