Linux Shell Learning Note two shell command line PWD CD

Start Linx Shell's first article today

Today describes how PWD and CDs are used.

The pwd means "Print working Directory", which displays the current location.

PWD also has other available parameters-L (uppercase),-p (uppercase)

-L is the same as the PWD showing the current user's location

-p Display the user's current physical location and PWD are the same

In fact, you can use PWD directly.

CD can simply think of directory switching

For example, currently on the/root/desktop, you can switch directly to the/ROOT/Desktop/tools folder location and the CD command under Windows similar

There are other different uses of CDs

CD back to the current user's host directory

Cd-back to previous working directory

Cd.. Back to the top level directory

Cd.. /.. Back to upper level directory

Cd/bin switch to the bin in the root directory

The CD bin switches to the current directory in the bin (bin can make any folder)

In addition, I am also the first time to learn Linux, it is inevitable that the directory structure is not understood, such as to enter the desktop directory under/root, because the language version of the English version of the desktop, the Chinese version of the table, often confused. So I like cd/root to go into the desktop under root

This summary concludes!
