These are rough notes from whatever I was working on, interested in or thinking about at the time. They vary greatly in quality and length, but prove useful to me, and hopefully to you too!

Modify bash history

Using bash history to try and find a previous command, I found it had vanished and there was a mysterious * present against the line, which I had never seen before:

   56  vi /etc/resolv.conf
   57  sudo systemctl restart dnsmasq
   58*
   59  curl foo.bar

Some searching found out this indicates the line has been modified.

It turns out modifying bash history is rather simple: press up until you find the line, modify it, then press down. I must have modified the history by accident.
