# bar Displays battery, date and time in a small bar placed in a corner of the screen. Bar can be forced into background with `-b` option. Corner can be chosen by specifying it with `-p` option, the value is first letters of top/bottom and left/right, ie `lt` would place it in the left top of the screen. Bar is centered horizontally if no "top" or "bottom" specified for its position. `bar` reads additional data from standard input and displays it along with other information.
