NAME

	bar – display a bar

SYNOPSIS

	bar [ –b ] [ –d dateformat ] [ –p position ] [ –s separator ]

DESCRIPTION

bar displays a small window with current battery charge, date and time. Additional data may be displayed by writing lines of text to its standard input. Data items should be separated between each other with a chosen separator character with spaces on both sides of it. The default separator is │ (Unicode codepoint 0x2502). Bar reacts to mouse clicks by writing the "clicked" portion of the text (enclosed by the separator) to standard output. This can be used to perform additional actions by a custom script. See Examples section. By default, bar is placed at the bottom right corner of the screen. This can be changed by specifying option –p with first letters of the required placement: l for "left", r for "right", t for "top" and b for "bottom". If neither left nor right is chosen, the window will be placed in either top or bottom center. Bar keeps itself as a top window. To make it stay at the bottom, use –b . Separator can be changed with –s option. Date and time format may be set using –d option, see tmdate(2).

EXAMPLES

	An example of how bar can be used along with riow to control zuke playback via mouse clicks: #!/bin/rc rfork ne fn mybar { sed –u 's/$/ │    ⏮ │    ⏯ │    ⏭/g' \ | bar \ | awk –v 'c=plumb –d audio ''key ' ' /⏮/{system(c"<''")} /⏯/{system(c"p''")} /⏭/{system(c">''")} ' >[2]/dev/null } riow </dev/kbdtap >/dev/kbdtap |[3] mybar The script is used instead of executing bar directly.
