imsettings-switch

imsettings-switch(1)													      imsettings-switch(1)

NAME

       imsettings-switch - Switch Input Method

SYNOPSIS

       imsettings-switch [ -hnqrx ] [ --no-update ] [ --quiet ] [ --restart ] [ --read-xinputrc ] [ --help ] [Input Method name | configuration
			 filename]

DESCRIPTION

       imsettings-switch switches Input Method which is managed under imsettings. Either Input Method name or configuration filename are  required
       unless --read-xinputrc option is specified to determine the target from $HOME/.config/imsettings/xinputrc or $xinputrcdir/xinputrc.

OPTIONS

       This  program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
       below.

       -n --no-update
	      Do not update $HOME/imsettings/xinputrc. without this option, imsettings-switch will updates it with the targeted Input Method.

       -q --quiet
	      Do not show any messages except errors.

       -r --restart
	      Restart the given Input Method or one which is determined from xinputrc by --read-xinputrc option.

       -x --read-xinputrc
	      Determine the targeted Input Method from $HOME/imsettings/xinputrc or $xinputrcdir/xinputrc if not available.

       -h --help
	      Show summary of options

       Input Method name
	      Switch Input Method to Input Method name.

       configuration filename
	      Switch Input Method to configuration filename.
