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. Data items should be
separated between each other with a chosen separator charac-
ter 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 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
}
BAR(1) BAR(1)
riow </dev/kbdtap >/dev/kbdtap |[3] mybar
The script is used instead of executing bar directly.
