       glob - Return names of files that match patterns


       glob ?switches? ?pattern ...?


       This  command  performs file name “globbing” in a fashion similar to the csh shell or bash
       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 characters.

       -join  The  remaining  pattern arguments, after option processing, are treated as a single
              pattern obtained by joining the arguments with directory separators.

              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
              specified in the list.  Glob will return all files which match at least one of  the
              types  given.  Note that symbolic links will be returned both if -types l is given,
              or if the target of a link matches the requested type. So, a link  to  a  directory
              will be returned if -types d was specified.

              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. 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

                     glob -type d *
                     glob */

              except  that  the  first  case doesn't return the trailing “/” and is more platform

       --     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, which are a
       superset of those supported by string match:

       ?         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 sub-patterns 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.

       When the glob command returns relative paths whose filenames start with a tilde  “~”  (for
       example  through  glob  *  or glob -tails, the returned list will not quote the tilde with
       “./”.  This means care must be taken if those names are later to be used with  file  join,
       to  avoid  them  being  interpreted  as  absolute  paths  pointing  to a given user's home


       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

       Since the backslash character has a special meaning to the  glob  command,  glob  patterns
       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”.


       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}*
