Exec
parameter variablesLegacy-Mixed
Encoding (Deprecated)Exec
parameter variables #
Each Exec
field may take a number of arguments which will be
expanded by the file manager or program launcher and passed to the
program if necessary.
Literal %
characters must be escaped as %%
, and adding new
format characters is not allowed. It's a fatal error to have an
Exec
field with a format character not given in the spec (exception
to this are the deprecated format characters which can be ignored,
that is expanded to no parameters, by the implementation).
Again for emphasis: nonstandard extensions are
not allowed here - you must add an X-Foo-Exec
field if you have
nonstandard Exec
lines.
The escaping of the exec parameters is done in the way the mailcap specification describes. Take a look at RFC 1524 (http://www.ietf.org/rfc/rfc1524) for more information.
Recognized fields are as follows:
%f |
A single file name, even if multiple files are selected. The system
reading the desktop entry should recognize that the program in
question cannot handle multiple file arguments, and it should
should probably spawn and execute multiple copies of a program
for each selected file if the program is not able to handle
additional file arguments. If files are not on the local file system
(i.e. are on HTTP or FTP locations), the files will be copied to the local
file system and %f will be expanded to point at the temporary
file. Used for programs that do not understand the URL syntax.
|
%F | A list of files. Use for apps that can open several local files at once. |
%u | A single URL. |
%U | A list of URLs. |
%d |
Directory containing the file that would be passed in a %f field.
|
%D |
List of directories containing the files that would be
passed in to a %F field.
|
%n | A single filename (without path). |
%N | A list of filenames (without paths). |
%i |
The Icon field of the desktop entry
expanded as two parameters, first
--icon and then the contents of the
Icon field. Should not expand as any
parameters if the Icon field is empty
or missing.
|
%c |
The translated Name field associated with the desktop entry.
|
%k | The location of the desktop file as either a URI (if for example gotten from the vfolder system) or a local filename or empty if no location is known. |
%v |
The name of the Device entry in the desktop file.
