In the development of the company, the development of the program in the local test is normal, but in the test environment is problematic. The first reaction is to look at the log file and see what the error message is in the log file. I carried out the Vim Log.txt, and then the direct card to die, can not open.

What to do, I still have to check AH. Using the Cat command, although the card is not dead, but the display of the document is obviously wrong, how to do?

Asked the company's predecessors only know, look at the log file, with the tail command, I direct vim open, not to die only strange!

Tail-f Log.txt #显示最后的10行

Tail-n Log.txt #显示最后的100行
