In the company we received the instruction to run the following commands every morning, but the current project manager did not know to answer the reason and in the search in the internet did not get a good answer.
sudo apt-get update
sudo apt update
sudo apt-get upgrade
sudo apt upgrade
Another detail that caught my eye is that it does not have a sequence to run, it will suit the developer.
The machine is used to develop front-end but the lines that are updating with the commands do not see anything of npm , gulp , bower or php , which are the applications we use, so what the impact of running these commands.
