有效使用linux的7个好习惯

Posted 7 months ago at 1:09 am. 0 comments

不用使用root登录，原因：

1. Well imagine you’re on the trapeze without a safety net,
   frightening isn’t it? Well that’s effectively what you are doing when
   you login as root, you can inadvertently hose your whole system
2. You are at the risk of running malware. Any program that is started under root mode will automatically be given root privileges
   
3. If there is a common security hole that hasn’t been patched yet, you could be totally “pwned”
4. It’s common Unix convention, never run anything in root
   mode unless absolutely necessary. If a non-admin program asks for root
   access, you should be suspicious

尽量使用 su,sudo,gksu,kdesu

• Use “sudo” or “su” , and kill the session when your done
• If you don’t know how to do it in the command line, use “gksu” or “kdesu”. For example, press alt+f2 and type “gksu nautilus“. Close the app as soon as you finish

注意文件命名

• As a rule of thumb, only use alphanumeric characters, hyphens, periods, and underscores
• Avoid special symbols like dollar signs, brackets, and
  percentages. These symbols have special meanings to the shell, and
  could cause conflicts
• Avoid using spaces, handling files with spaces in the
  terminal is kind of awkward. Replace spaces with either hyphens or
  underscores

把 /home 放在不同的分区

杀死崩溃进程

1. I have the “force quit” applet on my taskbar, if any app
   starts to act up just click on the “force quit” icon and then kill the
   app
2. If that doesn’t work, draw up a terminal and type “ps -A” , and take note of the Process ID (PID) of the culprit app, then kill it. “kill PID”
3. Use the “killall” command, for example, “killall firefox-bin”
4. If your whole GUI is frozen, and drawing up a terminal is
   impossible, then press CTRL-ALT-F1, this will take you to another
   terminal, and virtually a whole new session. From there kill the
   culprit app using step 2 and 3.
5. If that doesn’t work, you might want to restart your GUI
   using the CTRL-ALT-Backspace combo. Beware, that this will kill all
   your GUI apps currently running
   
6. Invoke CTRL-ALT-F1 and do CTRL+ALT+DEL from here. This
   will not instantly reset your system, merely perform a standard reboot,
   it’s safe. (Assuming you want to restart and CTLR-ALT-F1 works)
   
7. Finally if nothing works, don’t rush to the hard reset button, try to Raise a Skinny Elephant
