sysinfo

A small tool to print system information on Apple machines.

Quick start

git clone git@github.com:zeusdeux/sysinfo.git
# OR
git clone https://github.com/zeusdeux/sysinfo.git

cd sysinfo
make -B
./.build/sysinfo

You can then symlink sysinfo from a folder in your $PATH to <path to sysinfo repo clone>/.build/sysinfo or add <path to sysinfo repo clone>/.build/sysinfo to your $PATH.
