I started a github project which includes some helpful tools and scripts for your Raspberry Pi (or actually any other Linux based system).
To get you started, just clone the repository and add the directory to your
PATH by using the utils script and you should be all set.
git clone https://github.com/afritzler/raspberry-pi-tools.git cd raspberry-pi-tools ./utils/add_to_path
Currently there are two scripts availble
pi-temp: Displays the current CPU and GPU temperature
CPU temp=56.2'C GPU temp=56.8'C
pi-motd: MOTD script
I plan to add a few more in the future. Feel free to provide comments and ideas for new tools and scripts.
