Linux Command records (1)

During this period of time, we found that if we use the automatic update function of Fedora 10, it will easily cause the machine to die. During the next restart, we will not be able to access the interface, black screen (miserable !) Some commands or configurations frequently used during Linux installation are as follows:

1. Enable sudo

Under root, modify the/etc/sudoers 440 permission and add Wei all = (all) All

Save the file and modify the File Permission to 440.

2. font (or other fonts)

Copy Microsoft fonts to/usr/share/fonts/ZH _

CN, set the permission to 777, and then run

# Mkfontscale

# Mkfontdir

# FC-Cache-FV

In this way, a font is loaded in the system.


3. Use ls color in some environments

Use alias ls = "ls -- color"


4. Modify the time zone

• Query the name of the time zone to be replaced in the/usr/share/zoneinfo/directory.
  

• Remove the original localtime file; # mv/etc/localtime-old
• Create a new localtime file and link the corresponding time zone file # ln-S/usr/share/zoneinfo/Asia/Shanghai/etc/localtime
