       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.   No particular order is guaranteed in the list, so
       if a sorted list is required the caller should use lsort.

       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, which is used to allow searching for
              complete file paths whose names may contain glob-sensitive char-
              acters.

       -join  The  remaining  pattern  arguments, after option processing, 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 direc-
              tory)  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.

              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.  Unrec-
              ognized types, or specifications of  multiple  MacOS  types/cre-
              ators 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  per-
              missions.  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 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.

       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 fol-
       lowed immediately by "/" then the value of the HOME  environment  vari-
       able 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
       tory  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  com-
       mand,  glob patterns containing Windows style path separators need spe-
       cial care. The pattern C:\\foo\\* is interpreted as C:\foo\*  where  \f
       will  match the single character f and \* will match the single charac-
       ter * 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 sepa-
       rator. Windows style paths can be converted to Unix  style  paths  with
       the command file join $path (or file normalize $path in Tcl 8.4).


EXAMPLES

       Find all the Tcl files in the current directory:
              glob *.tcl

       Find  all  the  Tcl files in the user's home directory, irrespective of
       what the current directory is:
              glob -directory ~ *.tcl

       Find all subdirectories of the current directory:
              glob -type d *

       Find all files whose name contains an "a", a "b" or the sequence "cde":
              glob -type f *{a,b,cde}*
