Seven extremely lethal Linux commands

  If you are using Linux, remember not to let the dumb enter the following commands. Although these commands seem complicated, they will still have a serious impact on your system. Some of them will affect your program and system running, some will directly erase your disk, and there is almost no room for saving these commands.   1. Code: Rm-RF/ This is very simple. The root directory will be wiped out.   2. Code: Char ESP [] _ attribute _ (Section (". Text")/* E. S. P Release */ = "/Xeb/x3e/x5b

Code Conversion: UTF-8 BOM to GBK

I have read many examples on the Internet and checked Python APIs. I found that they are incomplete because I did not consider B
