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'
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.
This function is very useful, but be very careful, read it first and then delete it, if you make a wrong directory, you will die miserably
I think most of the current Linux supports Access Control List (ACL). With filesystem ACLs enabled, We can set additional permissions to different users or groups. This allows us to set the file system permissions of different users more freely. Go straight to the command.
