Linux on Windows -1-: debian introduction

1. 1. Introduction

As I learned PowerShell on Windows, I missed the Linux shell. If you want to play with Linux shell commands on Windows, there is a method called Cygwin (Isn't it still there?), But since it's a good idea, try building a Linux virtual environment on Win with WSL.

2. environment

The versions of Windows are as follows.

C:\Users\hisabo>systeminfo

hostname:               HISABO-PC
OS name:                  Microsoft Windows 10 Home
OS version:          10.0.18363 N/A build 18363
OS manufacturer:              Microsoft Corporation
OS configuration:Standalone workstation
OS build type:        Multiprocessor Free
... Below, abbreviated ...

3. 3. Where to aim

--Build a debian environment with WSL on Windows.

4. let's try it

Find Linux in the Microsoft Store

I thought that there was only ubuntu, but since there was debian, I changed it to debian. Certainly the size was 77MB, so there would be no GUI environment. That is more convenient.

When I started debian after installation, I got an error. Refer to the following page and change the Windows settings to enable WSL.

Reference: PC studio (link)

When I started it again, it worked. For the time being, I registered the user (user name, password) and the shell started up. It's a wonderful CUI.

For the time being, update the package.

hisabo@hisabo-PC:~$ sudo apt-get update

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

What is the shell?

hisabo@hisabo-PC:/etc$ echo $SHELL
/bin/bash

It's bash.

Just in case, check the login shell in / etc / passwd. It's bash.

What is the Japanese environment (simple survey)

Check the input method with vi (vim). I tried as long as I remember how to change to Japanese input mode, but none of them hit. At the very end, when I pressed the half-width / full-width key, I was able to input Japanese smoothly. I saved it and checked it with cat, more, less, and view, but I can see Japanese even when browsing. At first glance, there seems to be no problem.

Check the character code and locale

hisabo@hisabo-PC:/etc$ echo $LANG
en_US.UTF-8
hisabo@hisabo-PC:/etc$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
hisabo@hisabo-PC:/etc$ locale -a
C
C.UTF-8
en_US.utf8
POSIX
hisabo@hisabo-PC:/etc$       

After all it is UTF-8. Isn't there euc at this time? I noticed that it's not ja_JP.UTF-8, right? Well, let's find out later.

Since there was no man, install man

I typed a command to try using awk, but I forgot because I haven't used it for a long time. I tried to find out with man, but man doesn't seem to be installed by default. install.

hisabo@hisabo-PC:/etc$ sudo apt-get install man

In the days when Google wasn't there, I used man to find out how to use commands. It's a good time now. There are most answers on the net.
