This Page contains various bits and pieces of Raspberry Pi information that I’ve collected/discovered/invented. While it’s meant to be a readily available source for me, I’ve made some effort to document the information just in case other visitors happen upon this page. Detailed tutorials can be found in the following child pages

rsync -aAXv

# Sends the current set of packages to a file
sudo dpkg --get-selections > package_list
# Restores that set of packages
