    NAME
           lxc-execute - run an application inside a container.
    
    SYNOPSIS
           lxc-execute
    {-n name} [-f config_file] [-s KEY=VAL] [-- command]
    
    DESCRIPTION
           lxc-execute runs the specified command inside the container specified
           by name.
    
           It will setup the container according to the configuration previously
           defined with the lxc-create command or with the configuration file
           parameter.  If no configuration is defined, the default isolation is
           used.
    
           This command is mainly used when you want to quickly launch an
           application in an isolated environment.
    
           lxc-execute command will run the specified command into the container
           via an intermediate process, lxc-init.  This lxc-init after launching
           the specified command, will wait for its end and all other reparented
           processes.  (to support daemons in the container).  In other words, in
           the container, lxc-init has the pid 1 and the first process of the
           application has the pid 2.
    
           The above lxc-init is designed to forward received signals to the
           started command.
    
    OPTIONS
           -f, --rcfile config_file
    	      Specify the configuration file to configure the virtualization
    	      and isolation functionalities for the container.
    
    	      This configuration file if present will be used even if there is
    	      already a configuration file present in the previously created
    	      container (via lxc-create).
    
           -s, --define KEY=VAL
    	      Assign value VAL to configuration variable KEY. This overrides
    	      any assignment done in config_file.
    
           --     Signal the end of options and disables further option
    	      processing. Any arguments after the -- are treated as arguments
    	      to command.
    
    	      This option is useful when you want specify options to command
    	      and don't want lxc-execute to interpret them.
    
    COMMON OPTIONS
           These options are common to most of lxc commands.

    	      is an alphanumeric string.
    
           --rcfile=FILE
    	      Specify the configuration file to configure the virtualization
    	      and isolation functionalities for the container.
    
    	      This configuration file if present will be used even if there is
    	      already a configuration file present in the previously created
    	      container (via lxc-create).
