Wrong month, please use 1-12 months such information, what, you think I read English, ha, all by guessing, meaning I also do not understand, almost that means, in the terminal words can be copied down to the Youdao

Input BC will show a large segment of the information, first of all, the version number, the other I do not understand, not much to say (the English dregs home (-_-!!) )

Input 1+2 Press ENTER, the result is displayed, but the result of this calculation is an integer, if the results of the calculation to show the decimal point, then you enter, scale=2 specify to retain two decimal places

The above a large section of content knocked down, I believe that the small partner a bit of egg pain, the input has been at the bottom of the strange upset, and here to tell you a clear screen command:clear

As I said earlier, this is the option parameter for the command, which is to use the man command: Use the format man date
