Using pcregrep to extract reference links from Markdown documents

Using grep (well, pcregrep) to display the labels of reference style links in a Markdown document:

$ pcregrep --only-matching=1 \  # Only display the match from group 1
  "\[.*?\](\[.*?\])" \          # Find [text][label] reference style links
  /path/to/document.md | \      # Path to the markdown document
  sort                          # Optionally sort the output

I had the regexp working in grep but couldn't capture just the group I was interested in. This Stack Overflow answer suggested pcregrep.

NAT and FORWARD with Ubuntu’s ufw firewall

UFW

I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.

Instructions for exporting/importing (backup/restore) GPG keys

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...
