Supported Platforms

Linux

Kernels >= 2.6.24 are supported; support for older kernels is not a priority, but may be added later.

*BSD

Most BSDs should be supported: as long as you have sysctlbyname, you should be fine. BSD systems known to work:

• DragonFly BSD
• FreeBSD

BSD systems that should work:

• NetBSD
• Midnight BSD
• (Anything based on FreeBSD)

BSD systems known not to work:

• OpenBSD

Dependencies (v3.0+)

• GNU Autotools
• C99 compliant C compiler

The GUI (Graphical User Interface) requires gtk2 and the configure script will need pkg-config, but these are optional, since you can opt out of building GUI using the --without-gtk2 configure flag.

Building

1. autoreconf -i
2. ./configure
3. make

Installing

Just place zbatc (zbatt-color) and zbatt (zbatt-text) where ever you want them and add the appropriate stuff to your terminal prompt.

Examples

Styles

Git

./zbatc -c 32; ./zbatt -p -f +; ./zbatc -c 31; ./zbatt -m -e -

Shells

Zsh

PROMPT="%{$(./zbatc)%}$(./zbatt)%{�[0;0m%} %m%# "

## run TRAPALRM every $TMOUT seconds
TMOUT=60 # refresh the terminal prompt every 60 seconds

TRAPALRM () {
    zle reset-prompt # refreshs the terminal prompt
}

Bash

PS1='\[$(./zbatc)\]$(./zbatt)\[\033[0;0m\] [\h \W]\$ '

Mksh (Korn Shell)

PS1=$'$(./zbatc)'$(./zbatt)$'\033[0;0m'\ ["$(hostname)"]\

Tcsh

set prompt="%{`./zbatc`%}`./zbatt` %{\033[0;0m%}%m "

Notes

Zsh

As long as you use the TMOUT and TRAPALRM/zle reset-prompt stuff, your Zsh prompt should refresh itself every 60 seconds.

Bash

AFAIK there is no way to periodically refresh a bash prompt without either running clear/Ctrl-L or pressing enter, which causes the prompt to be redrawn.
