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'
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.
This article uses CentOS 6.2 to rebuild curl and git. The main reason is that the operating system is too old, so I directly build the latest version of git from source.
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.
