bash customization. Add battery status and color codes to your command prompt.

bash customization

I got some linux devices like Notebooks, RPi's and SailfishOS Smartphones. It's anoying working remotly via ssh on this devices when powered by battery, not knowing the battery status. So i added this cool function to the bash command prompt. Additionally i added different colors for the prompt for each device and user.

Add this at the beginning of your .bashrc file or /etc/bashrc for global use. I found the battery code on a pine64 forum but it had some issues. I fixed it for my best use case.

Btw. since Sailfish OS 4.x update replaces /bin/bash with a symlink to /usr/bin/busybox, you have to install gnu-bash to use .bashrc.

On SailfishOS, fingerterm is the default terminal app. There is an odd Problem with the first character of a string value in PS1 prompt. Maybe it is related to libreadline and the octal escape sequence \001 and \002. It leads to a wrong color for the first character of a string value when using any character before the string value" Using havoc as a terminal app will work without problems. However, if you use fingerterm, you can move the $BATSTT value before the percentage value. This problem will ocur on SailfishOS/fingerterm only localy on the device.
