The following commands are common to both Linux and MacOS
find . -type f -mtime -7 -name "*.php"
| parameter | illustrate |
|---|---|
| . | Start searching under the current directory, including subdirectories. |
| -type f | f means the type is file, d means the type is directory |
| -mtime -7 | -7 (minus seven) represents files that have changed within 7 days. |
| -name "*.php" | Only find files with the extension php |
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.
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.
The instructions are different on MacOS or Linux, but achieve the same effect. Let's see how to display yesterday's date with the date command.
