If you have to attach external displays and projectors on a regular basis (or switching workspace environments a couple of times a day) you might have searched for a way to exchange primary and secondary display in OSX with a shortcut as well - the official way is to drag and drop the menu bar in the system preferences each time, quite a hassle:
The documentation for the tool can be listened with the command
and will give you:
Usage: cscreen [-d
] [-x ] [-y ] [-r ] [-s ] [-v] [-m] [-f] [-l] [-h] [-d ] : specifies the bit depth (bits per pixel) [-x ] : specifies the width in pixels [-y ] : specifies the height in pixels [-r ] : specifies the refresh rate in Hz [-s ] : specifies which display to use (defaults to main display) use a as the option to -s to specify the action on all displays [-i ]: picks a display based on CGDirectDisplayID (permanent per display) continue to use '-s a' for "all displays" [-v] : display valid modes (use -s to specify display or nothing for the default) [-m] : require an exact match [-f] : forces settings (ignores safety mechanisms; USE AT YOUR OWN RISK) [-l] : lists the current displays and modes [-p] : sets the requested display to have the menu bar [-h] : displays the usage Note: Using -p will change the display index so you will likely want to use -l again to show the current displays if you wish to use -p a second time.
Update: I am still on 10.9, I was told the whole situation has gotten better with 10.10..
