The English word abbreviation for Linux common commands

Linux commands usually consist of the following three parts:

Command[-option][argument]

• command is the order to run itself, and plainly is a software (program)
• option is optional, that is, some commands do not have options, and the options are to control the state and behavior of the command.
• argument is a parameter, is the command to manipulate the file, path, data, etc., is also optional, because some commands do not need to manipulate these content, if not, select the default

For example, cooking is an order, and we can add options such as fast and tasty, and the parameters are the ingredients, so we can say "make a tasty pork."

The most essential difference between the SU command and the Su-command is that the former simply switches the root identity, but the shell environment is still the shell of the normal user, and the user and the shell environment are switched to root. The PATH environment variable error does not occur unless you switch the shell environment. After the SU switch to the root user, PWD, found that the working directory is still the normal user's working directory, and after the Su-command switch, the working directory becomes the working directory of root. Use the echo $PATH command to see how the Su and Su-future environment variables are different. And so on, to switch from the current user to another user, you should use the Su-command.

The shell is the interaction between the user and the job system, the user modifies its environment, sets or cancels the environment variables of the shell, caters to the user's needs and hobbies, the shell itself is a computer program, written in C, to assist the user and the operating system communication between the design, Manage user and core (Dernel) dialogue, and change the operating system instructions to machine code, in fact, PC users commonly used DOS itself when a shell.
