1
Have you ever opened a Linux terminal and wondered, why is everything inside a single slash?
2
Where is the C drive?
3
Why are there folders called slash bin, slash etc, slash usr, and slash var?
4
And why does
5
Linux seem so different from Windows?
6
If you've ever been confused by the Linux file system, don't worry.
7
In the next few minutes, you'll understand how
8
Linux organizes everything, what each major directory is used for, and how to remember them forever.
9
Let's start from the very top.
10
Unlike Windows, Linux doesn't have separate drives like C, D, or E.
11
Instead, Linux has a single starting point called the root directory.
12
It's represented by just one character, slash.
13
Think of it as the trunk of a tree.
14
Every file, every folder, every application, every hard drive, and even USB devices eventually become part of this one tree.
15
No matter where something is stored, everything starts from the root.
16
That's one of the biggest differences between
17
Windows and Linux.
18
Now let's walk through the most important folders.
19
We'll start with one you'll use almost every day, slash home.
20
This is where user files are stored.
21
If your username is John, your personal folder will usually be slash home slash John.
22
This is where you'll keep your documents, downloads, pictures, videos, projects, and everything related to your account.
23
Think of it like your personal workspace.
24
Every user gets their own home directory, keeping files separate from other users on the system.
25
Next is the root user's home directory, which often confuses beginners.
26
There's a folder called slash root.
27
This is not the root of the file system.
28
It's simply the home directory of the administrator account, known as the root user.
29
So remember, slash is the root of the entire file system.
30
Slash root is just one folder inside it.
31
Now let's look at where
32
Linux keeps its programs.
33
You'll often hear about slash bin.
34
The word bin stands for binaries.
35
This folder contains essential command line programs that
36
Linux needs to function.
37
Commands like lscp, mv, cat, mkdir, and many others live here or in related binary directories.
38
Think of slash bin as the toolbox that allows
39
Linux to operate.
40
Without these commands, the system wouldn't be very useful.
41
Another important directory is slash sbin.
42
The s stands for system.
43
This folder contains administrative tools used for managing the operating system.
44
Commands for networking, disk management, booting the system, and system recovery are commonly found here.
45
Most regular users don't use these commands every day, but system administrators certainly do.
46
Now let's talk about one of the most important folders in Linux, slash etc. This is where
47
Linux stores configuration files.
48
Almost every application has a configuration file somewhere inside slash etc. Want to change network settings?
49
Edit a configuration in slash etc. Need to configure SSH?
50
It's inside slash etc. DNS settings?
51
Also inside slash etc. Instead of storing configuration inside the application itself, Linux keeps most settings here.
52
A A simple way to remember it is, slashetc is the settings folder for your entire operating system.
53
Next is a directory beginners often misunderstand, slashusr.
54
Many people assume it stands for user.
55
It actually comes from Unix System Resources.
56
This folder contains most of the software installed on your system.
57
Applications, libraries, documentation, development tools, and shared resources all live here.
58
For example, slash -usr -slash -bin contains thousands of executable programs.
59
Think of slash -usr as the main software library of your Linux machine.
60
Applications also need shared code.
61
That's where slash -lib comes in.
62
Libraries are reusable pieces of code that many applications share.
63
Instead of every program including the same code repeatedly, Linux stores common functionality in shared libraries.
64
This saves disk space and makes updates much easier.
65
You can think of libraries as shared building blocks that applications borrow whenever they need them.
66
Now let's look at where
67
Linux stores temporary files.
68
Slash TMP.
69
As the name suggests, this directory is used for temporary data.
70
Applications create files here while they're running.
71
Many Linux systems automatically clean this directory during reboot.
72
So don't store anything important inside
73
Slash TMP unless you're okay with losing it.
74
Another useful folder is slash var.
75
The word var stands for variable.
76
Unlike application software, which rarely changes, this folder contains files that constantly grow and change.
77
Things like system logs, application logs, email queues, databases, printer queues, and cache files.
78
Whenever you're troubleshooting
79
Linux, slash var slash log is one of the first places you'll check
80
because it contains log files that explain what the system has been doing.
81
Now, suppose you plug in a USB drive.
82
Where does it appear?
83
Usually inside directories like slash media or slash MNT.
84
The slash media directory is commonly used for automatically mounted devices, such as USB drives and DVDs.
85
The slash MNT directory is often used by administrators when manually mounting disks, network shares, or other storage devices.
86
This is another major difference from Windows.
87
Instead of assigning a drive letter, Linux simply attaches the new storage somewhere within the existing directory tree.
88
You'll also come across slash dev.
89
This one is fascinating.
90
In Linux, almost everything is treated as a file.
91
Hard drives, USB devices, keyboards, mice, printers, even terminals.
92
They all appear as files inside slash dev.
93
For example, your hard disk might appear as slash dev slash sda.
94
This design allows programs to interact with hardware using the same file -based interface they use for regular files.
95
It's one of the reasons
96
Linux is so flexible.
97
Another important folder is slash proc.
98
Unlike normal directories, slash proc doesn't actually exist on your hard disk.
99
It's a virtual file system created by the Linux kernel.
100
It contains live information about running processes, CPU usage, memory, system configuration, and much more.
101
Whenever monitoring tools need information about your system, they often read it from Slash Proc.
102
Think of it as a live dashboard of what's happening inside
103
Linux right now.
104
There's also Slash Boot.
105
As the name suggests, this folder contains everything needed to start Linux.
106
The Linux kernel, bootloader files, and startup configuration all live here.
107
Without these files, your operating system wouldn't be able to boot.
108
So how do you remember all of these?
109
Instead of memorizing random folder names, group them by purpose.
110
User files live in slash home.
111
Programs live in slash bin, slash sbin, and slash usr.
112
Configuration files live in slash, etc. Shared libraries live in slash lib.
113
Logs and changing data live in slash var.
114
Temporary files live in slash TMP.
115
Hardware devices appear inside slash dev.
116
System information comes from slash proc.
117
Boot files live in slash boot.
118
External storage is mounted under slash media or slash MNT.
119
Once you understand this structure, navigating Linux becomes far less intimidating, and you'll know exactly where to look when installing software,
120
changing configurations, troubleshooting problems, or managing servers.

この動画での練習方法
- まず声を出さずに動画を最後まで聞き、知らない単語をメモします。
- 通常の速度で一文ずつシャドーイングし、話し手のリズムに合うまで繰り返します。
- 自分の声を録音して元の音声と比べます。folder, directory, configurationなどの単語に特に注意しましょう。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
