exo-open - Open URLs and launch preferred applications
exo-open --launch [category] [[parameter]...]
exo-open is a command line frontend to the Xfce Preferred Applications framework. It can
either be used to open a list of urls with the default URL handler or launch the preferred
application for a certain category.
exo-open either takes a list of URLs and tries to open each of them using the default
handler, or, when using the --launch tries to launch the preferred application for a
certain category, optionally passing any number of parameters to the application.
Print brief help and exit.
Print version information and exit.
When using the --launch option and this option is specified as well, the application
will be run in the given directory. This is primarily useful when running the
preferred TerminalEmulator from another application and you want the command in the
terminal window to be run in a specific directory.

parameters..., where category is either WebBrowser, MailReader, TerminalEmulator or
If you do not specify the --launch option, exo-open will open all specified URLs with
their preferred URL handlers. Else, if you specify the --launch option, you can select

exo-open allows users and developers to open the preferred email composer from the command
line by simply invoking exo-open mailto:[email protected]. This will open the composer window
with [email protected] as the recipient. This syntax is supported by all MailReaders. In
addition the MailReaders that ship as part of libexo also support extended mailto:-URIs
(but be aware that user-defined mailers do not necessarily support this), which allows you
to also specify default values for the subject and the body of the mail, add additional
recipients (both Cc: and To:) and attach files to emails. For example
mailto:[email protected]?cc=[email protected]&subject=Foo&attach=/foo/bar.txt tells the composer to
start an email to [email protected] and [email protected] with Foo in the subject and the file
/foo/bar.txt attached to the message.
