MS-DOS and Windows command line ftype command
The ftype command is a Recovery Console command that is available in the following Microsoft operating systems.
|fileType||Specifies the file type to examine or change.|
|openCommandString||Specifies the open command to use when launching files of this type.|
Type ftype without parameters to display the current file types that have open command strings defined. When ftype is invoked with only a file type, it displays the current open command string for that file type. Specify nothing for the open command string, and the ftype command deletes the open string for the file type. Within an open command string %0 or %1 are substituted with the file name being launched through the association. %* gets all parameters and %2 gets the 1st parameter, %3 the second, etc. %~n gets all the remaining parameters starting with the nth parameter, where n may be between 2 and 9, inclusive. For example:
ASSOC .pl=PerlScript FTYPE PerlScript=perl.exe %1 %*
would allow you to invoke a Perl script as follows:
script.pl 1 2 3
If you want to eliminate the need to type the extensions, then execute the following code:
The script could be invoked as follows:
script 1 2 3
See above Microsoft examples in the syntax for good examples of how this command can be used.
