pwd (print working directory)

what

return working directory name

options

The options are as follows:

     -L      Display the logical current working directory.

     -P      Display the physical current working directory (all symbolic
             links resolved).

     If no options are specified, the -L option is assumed.

比喻範例

資料結構：

        root 裡面有三個物件

                fruit(link to apple)
                apple(folder)
                banana(folder)

情境一：

cd root/fruit
pwd -L  
# /root/fruit

情境二：

cd root/fruit
pwd -P 
# /root/apple

還不知道如何應用的知識

link 有 soft link 和 hard link 兩種。當刪除 soft link 時，只會刪除 soft link ；當刪除 hard link 時，hard link 指向的物件也會被刪除。

why isn't the Terminal designed to display the absolute path by default?

for better readability (by limiting the information in the pane)
