Let's see how to display yesterday's date with the date command.
On MacOS, we pass the following command:
date -v -1d +'%Y-%m-%d'
On Linux:
date -d 'yesterday' +'%Y-%m-%d'
date -v -1d +'%Y-%m-%d'
date -d 'yesterday' +'%Y-%m-%d'
Load the environment variables of .env to the system
Sometimes we need to generate a random password, but do not know what to use? Here is a simple bash that allows us to easily generate a set of passwords on the terminal.
There may still be some old programs in some places, which can only run the old system. But you want to be able to execute and install some desired packages, you may try this method. Please note that if this system is important to you, please evaluate it yourself. It is recommended that you have a Docker environment and have a backup image before trying it.
