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 fol-
       lowing 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, which is used to allow searching for complete file paths |
	      whose names may contain glob-sensitive characters.				  |

       -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 |
	      (as  opposed to a directory) even when the names contain glob-sensitive characters. |
	      This option may not be used in conjunction with -directory.  For example,  to  find |
	      all  files  with	the same root name as $path, but differing extensions, you should |
	      use glob -path [file rootname $path] .* which will  work	even  if  $path  contains |
	      numerous glob-sensitive characters.						  |

       -tails											  |
	      Only  return  the part of each file found which follows the last directory named in |
	      any -directory or -path path specification.  Thus glob -tails -directory $dir *  is |
	      equivalent to set pwd [pwd] ; cd $dir ; glob *; cd $pwd.	For -path specifications, |
	      the returned names will include the last path segment, so glob -tails  -path  [file |
	      rootname ~/foo.tex] .*  will return paths like foo.aux foo.bib foo.tex etc.	  |

       -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 spec- |
	      ified  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 cre- |
	      ators  respectively.   Unrecognized  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 permissions.	The following are equiva- |
	      lent:										  |
			    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 (inclusive) will match.

       \x	 Matches the character x.

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

       On Unix, as with csh, a ``.'' at the beginning of a file's name or just after a ``/'' must
       be matched explicitly or with a {} construct, unless the ``-types hidden'' flag	is  given
       (since  ``.''  at  the  beginning of a file's name indicates that it is hidden).  On other
       platforms, files beginning with a ``.'' are handled no differently to any  others,  except
       the  special  directories  ``.''  and  ``..'' which must be matched explicitly (this is to
       avoid a recursive pattern like ``glob -join * * * *''  from  recursing  up  the	directory
       hierarchy as well as down).  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.

       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 ``~user-
	      name@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.

	      Since  the backslash character has a special meaning to the glob command, glob pat-
	      terns containing Windows style path  separators  need  special  care.  The  pattern
	      C:\\foo\\*  is  interpreted  as C:\foo\* where \f will match the single character f
	      and \* will match the single character * and will not be interpreted as a  wildcard
	      character. One solution to this problem is to use the Unix style forward slash as a
	      path separator. Windows style paths can be converted to Unix style paths	with  the
	      command file join $path (or file normalize $path in Tcl 8.4).

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