Useful Linux Commands
apropros - Useful for finding “appropriate” commands. i.e., apropros network will show useful commands related to networking.
man - RTM. Read The Manual. Enough said? i.e., man ls will let you read the manual for the command ls.
- list hardware. Needs elevated privileges to properly probe all of the system's hardware. Also useful to pipe the output into a paginator for easy reading. i.e., sudo lshw | less
will run the command with elevated privileges, then it pipes the output from that command into the text reader command less
To rebuild the keyrings (nuclear option)
sudo rm -fr /etc/pacman.d/gnupg
sudo pacman-key --init
