"Absolute path vs. relative path"

Absolute path: When we get a file, we write everything from the root directory to level two to more.

Finally found this file, this is the "absolute path"

Relative path: The relative position of the target file and my own file

Current directory:./.

Parent directory:. /   ..

On level two directory:. /.. /

/home/shuhua/beijing/haidian/shangdi

I want to go to the "Haidian" directory.

CD Haidian

Cd.. /reached Haidian with "relative path"

Cd/home/shuhua/beijing/haidian to Haidian via "absolute path" mode

We arrived at a directory there are two ways to choose "relative to the road" and "absolute path"

How to choose two ways, the less input information, choose which kind.

/home/shuhua/liaoning/shenyang/haidian/tiexi

/etc/sysconfig/network-script/
