Creating Filetypes

To define a filetype in the database

To specify the criteria for categorizing the file

You can use more than one criteria for a filetype. However, you should not use the FILE-PATTERN and PATH-PATTERN criteria in the same filetype.

	NOTE: Use of content-based filetyping will result in lower system performance. Wherever possible, use name- and location-based typing instead.

Example.  The Executable_Object_File filetype defined below applies to all files named with .o extensions that are executable (x) and (&) non-directories (!d).

   FILETYPE           Executable_Object_File

     FILE-PATTERN     *.o

     MODE             x&!d

      ...

   END

Example.  The QS_Source_File filetype defined below applies to all files with .c extensions in subdirectories of /projects/QS on any host.

   FILETYPE          QS_Source_Files

     PATH-PATTERN    *:/projects/QS/*/*.c

      ...

   END

Example.  The Final_pcl_graphics filetype applies to all files named QS*.pcl, located on host hphere, that are read-only (!w) and (&) not directories (!d) and not executable (!x).

   FILETYPE          Final_pcl_graphics

     PATH-PATTERN    hphere:*/QS*.pcl

     MODE            !w&!d&!x

      ...

   END

Example.  The Wingz_data filetype applies to all files with write permission containing the string WNGZ in the first 100 bytes.

   FILETYPE        Writable_Wingz

     CONTENT       0 100 string WNGZ

     MODE          w&!d

      ...

   END

To associate actions with filetypes

Example.  The following filetype definition creates a filetype for special "readme" files created by your system administrator that use the naming convention *.rm.

   FILETYPE SysReadMe

      FILE-PATTERN  *.rm

      L-ICON         SysReadMe.l

      S-ICON         SysReadMe.s

      ACTIONS        Open,Edit

   END

A special Respond action is defined below for the file. It opens a writeable copy of the file in Text Editor. When the file is saved and Text Editor is exited, the file is mailed to the system administrator (mail address sysadmin@utd).

   ACTION Respond

     ARG-TYPES     SysReadMe

     EXEC-STRING  /usr/bin/sh -c 'cp %(File)Arg_1% $HOME/readme.temp;       \

                   chmod +w $HOME/readme.temp;                          \

                   vuepad $HOME/readme.temp;   n                        \

                   cat $HOME/readme.temp | /usr/bin/mailx sysadmin@utd; \

                   rm $HOME/readme.temp' 

     WINDOW-TYPE   NO-STDIO

   END

Example: creating a personal filetype

The following steps create a personal filetype for graphics files for the QS project. The typing criteria is based on the entire path— the files must be on system hpaaa in subdirectories of /HomeDirectory/QS/graphics and end in *.tiff.

Example. 

Example: creating a system-wide content-based filetype

The following steps create a system-wide filetype for shar-ed files.
