Linux Shell Common commands daily one more

Freshman semester to learn the basic operation of Linux, has not been used for a long time, the virtual machine has not opened nearly half a year (as a computer professional juvenile really should not). To replenish this knowledge and lay the groundwork for future learning, now update a shell command and its subcommands every day, and you are welcome to view it. Commands are arranged alphabetically, and can be found on the internet, so that they are easier to view and less prone to missing commands.
