A Better Linux / Gnome Clipboard Experience

Anonymous (anonymous@undisclosed.example.com) — 2020-06-01T22:53:41+0000

A Better Linux / Gnome Clipboard Experience Linux has two different types of “clipboards”. I love the approach and switch back and forth depending on what I'm doing. But, the copy/paste clipboard (ctrl-c and ctrl-v) acts a little strange in Linux and particularly in Gnome. It seems unreliable to me.

Creating an SSH Tunnel / SSL Proxy

Anonymous (anonymous@undisclosed.example.com) — 2020-06-01T22:53:41+0000

Creating an SSH Tunnel / SSL Proxy You can use SSH to create a secure “tunnel”. Your traffic will be encrypted and sent through the secure tunnel. This has lots of advantages. It will encrypt data transmitted over a public WiFi connection to help prevent spying. It can get around firewall configurations. It can also hide your IP address (using the machine you SSH into instead of your own IP). Because SSH includes a socks proxy, it's very easy to setup.

Grep a Range of Lines

Grep a Range of Lines I was looking for a solution to grep through a file and return a range of lines. Although I didn't find exactly what I thought I wanted, I did find a workable solution. In this case, I wanted to search through a file looking for the name of a car dealership (Cool Auto). Once it found that line, I wanted one line BEFORE the match and 1000 lines after the match (essentially the part of the log file that deals with this particular dealership).
