the user, and send it/them to i3. This is useful, for example, for the the user, and send it/them to i3. This is useful, for example, for the
mark/goto command. mark/goto command.
The -F option takes a format string. In this string, every occurence of %s is
replaced by the user input.

== ENVIRONMENT == ENVIRONMENT
=== I3SOCK === I3SOCK
If no ipc-socket is specified on the commandline, this variable is used i3-input handles the different sources of socket paths in the following order:
to determine the path, at wich the unix domain socket is expected, on which
to connect to i3. * I3SOCK environment variable
* I3SOCK gets overwritten by the -s parameter, if specified
* if neither are available, i3-input reads the socket path from the X11
property, which is the recommended way
* if everything fails, i3-input tries +/tmp/i3-ipc.sock+
The socket path is necessary to connect to i3 and actually issue the command.
