opn - open files and URLs with associated programs
opn (--version | [--dry-run] PATHS...)
The opn command lets you open files and URLs with associated programs. It's intended to "just work" and to be trivial to configure.
The configuration resides in ~/.opnconfig; here's an example:
[browser]
browser: chromium
[associations]
mupdf: .pdf
emacs: .lhs .hs .py .c
chromium: .png .jpg .html .txt
mpv: .avi .mpg .mp4
djview: .djvu
Both [browser] and [associations] sections must be present and
nonempty. The [browser] section should in fact always have exactly one
key, namely browser. Comments must start at the beginning of the line
and start with ';' or '#'.
If asked to open a file with no matching extension, or a file without an
extension, opn tries to be a bit smart. For example, with the config
above, a header file, say foo.h, would be opened in emacs. The
reason is that header files have mime type text/x-c, the same type as
'.c' files, and thus opn "guesses" that '.h' files also should be
opened with emacs.
--dry-run : Display the command, or commands, that would be executed, then exit.
--version : Display version information.
--help : Display a short help message.
Open opn.hs in the application associated with the extension '.hs':
opn opn.hs
Open http://akc.is/ in the browser specified under the [browser]
section:
opn http://akc.is/
For each file in the current directory display the manner in which it would be opened:
opn --dry-run *
