Feb 09, 2020 There is no MAC OS. I boot up the mac from a USB where I have High Sierra. When I get to the picture where I can install MAC OS i go to the top and open a Terminal. When the original MAC 1 TB disk was in the imac, I had the same issue with terminal commands. Commands was'nt working. There was also no OS on the original disk. I was recently talking with someone that was constructing an If/Then and they wanted a simple echo to match only if a condition was not met. Given their other requirements it seemed a great use for a null operator, which in bash can be a colon (:). This has the equivalent of /dev/null, but with Continue reading Using a Colon As A Bash Null Operator.

Installation on other Linux
airgeddon is already included in some Linux distributions and repositories:
Repositories versions will have auto-update feature disabled in order to avoid breaking dependencies. There is a var at the beginning of the file, 'auto_update' can be set to 0 to turn off the auto-update feature.
Anyway, can be used with any Linux distro if you have installed the tools what script needs. The script checks for them at the beginning.
We will enumerate the categories and tools. The format will be: 'command -> possible package name'. The command can be included in different packages depending of the distro.
Bash version 4.2 or later needed.
Essential tools: <- the script doesn't work if you don't have installed all of them
Optional tools: <- not necessary to work, only needed for some features
Update tools: <- not necessary to work, only used for auto-update
Internal tools: <- these are internally checked. Not necessary to work, good to have
Is highly recommended to have the internal tools installed. They improve functionality and performance. For example, xdpyinfo allow the script to detect the desktop resolution in order to print windows in a better way.
