A critical vulnerability has been found in Bash, which affects almost all Linux/Unix distributions that use or have it installed. Luckily, there is a easy way to test to see if your version is vulnerable using a command line.
A while ago I had to sync files from one server to another. The reason? I was responsible for moving all the application and websites hosted on a old server to a new, faster server with better security and a updated operating system.

Managing a server using SSH and Command Line Access over the past few years has taught me a lot. It’s sometimes important to check how a server is doing in terms of load or you may simply want to check hard disk usage.
