## File Opener
`lf` does not come bundled with a file opener.
By default it tries to call `xdg-open` from `xdg-utils` package.
You can change the file opener using the opener option (e.g. `set opener mimeopen`).
Below are a few alternatives you can use:
- [libfile-mimeinfo-perl](https://metacpan.org/release/File-MimeInfo) (executable name is `mimeopen`)
- [rifle](http://ranger.nongnu.org/) (ranger's default file opener)
- [mimeo](http://xyne.archlinux.ca/projects/mimeo/)
- custom (using file extensions and/or mimetypes with `file` command)

Instead we could use the `ifs` option to set it for all commands (e.g. `set ifs :`).
This could be especially useful for interactive use (e.g. `rm $fs` would simply work).
This option is not set by default as things may behave unexpectedly at other places.
## Opening Files
You can use `open-file` command to open a file.
This is a special command called by `open` when the current file is not a directory.
Normally a user maps the `open` command to a key (default `l`) and customize `open-file` command as desired.
You can define it just as you would define any other command.
cmd open-file $IFS=':'; vim $fx
It is possible to use different command types.
cmd open-file &xdg-open "$f"
You may want to use either file extensions or mime types with `file`.
cmd open-file ${{
case $(file --mime-type "$f" -b) in
text/*) IFS=':'; vim $fx;;
*) IFS=':'; for f in $fx; do xdg-open "$f" &> /dev/null & done;;
