'''wm command''' ''window ?value?''

If ''value'' is specified, this command stores value in ''window'' 's '''WM_COMMAND''' property for use by the window manager or session manager and returns an empty string. ''Value'' must have proper list structure; the elements should contain the words of the command used to invoke the application. If ''value'' isn't specified then the command returns the last value set in a '''wm command''' command for ''window''. If ''value'' is specified as an empty string, the command deletes the '''WM_COMMAND''' property from window.

The '''wm command''' command is used to provide some level of compliance with the [ICCCM]. In order for the session manager to be able to restore an application, it must know how to start that application. The most basic way to do this is:

   wm command . [linsert $argv 0 $argv0]

You should also use the [wm client] command to set the application client, thus:

   wm client . [info hostname]
