Today we'll lay the groundwork for writing Python on Linux systems and introduce a few of the Linux commands we'll use.

1. ls command

ls command format:

ls [options] [file or directory]

Common options are:

-a displays all files, including hidden files (in dots ".") Files that begin with)

The leftmost set of data, which is composed of several characters of drexr-, represents the file permissions. d The directory of the beginning of the presentation;-The beginning of the ordinary file

2. CD command

CD command format:

CD [options] [parameters]

The file location will open the directory directly after the CD

We opened the video directory, using LS to see that there is a file called PYTHONVIP.

After CD Add ~ will return home directory

We first use the command CD in the '/usr/share/wordlists ' directory: Return to the top level, to the/usr/share directory

3. Touch command

Touch is used to build files, and this is simple. For example, we create a new call python.py file, directly in the terminal input touch python.py and then enter the good.

The first LS does not python.py this file, the second LS will have python.py this file.

4. mkdir command

mkdir English is the use of make Directory,mkdir command and the same as the Touch command, the direct command after the directory name can be, create a new directory called Woaipython.

As for the other copies of the Cut command or the graphical interface to be friendly, here is not a repeat.
