mimedb [OPTIONS] FILES...

\subsection mimedb-description Description
|
||||
|
||||
`mimedb` queries the MIME type database and the `.desktop` files installed on the system in order to find information on the files listed in `FILES`. The information that `mimedb` can retrieve includes the MIME type for a file, a description of the type, and the default action that can be performed on the file. `mimedb` can also be used to launch the default action for this file.
|
||||
|
||||
The following options are available:
|
||||
|
||||
- `-t`, `--input-file-data` determines the files' type both by their filename and by their contents (default behaviour).
|
||||
|
||||
- `-f`, `--input-filename` determines the files' type by their filename.
|
||||
|
||||
- `-i`, `--input-mime` specifies that the arguments are not files, but MIME types.
|
||||
|
||||
- `-m`, `--output-mime` outputs the MIME type of each file (default behaviour).
|
||||
|
||||
- `-f`, `--output-description` outputs the description of each MIME type.
|
||||
|
||||
- `-a`, `--output-action` outputs the default action of each MIME type.
|
||||
|
||||
- `-l`, `--launch` launches the default action for the specified files.
|
||||
|
||||
- `-v`, `--version` displays the version number and exits.
