Linux.

NixOS Ansible JumpHost.

Got the urgent need for a JumpHost that supports Ansible?

Boot a VM from an USB or ISO.

Built or got a new ISO that possibly auto-install and don't want to nuke your current system?

grep, but match a AND b.

Ever wondered how grep can be used with an AND instead of OR? I did.

Am I a VM?.

You got access to a Linux system. What is it? Is it a virtual machine?
