     BAR(1)                                                     BAR(1)

     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.

          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 speicifying 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.
