An adult who happened to be born into the IT industry!

Hello, nice to meet you.
I'm John, and I joined Beyond Inc. as a new graduate in April
I was born in Uzbekistan, came to Japan for the first time, and acquired knowledge of international business at a private Japanese university. I don't think anyone could imagine why I'm working in the IT industry. Not even I know. This
might be a boring story, but I would be happy if you would take a little time to read it.

My encounter with Linux

I graduated from high school in Uzbekistan, far from Japan.
To study business in Japan, the world's second-fastest economy, I enrolled in the international Ritsumeikan Asia Pacific University in Oita Prefecture.
During my university years, I only took business-related classes taught in English, so I never imagined I would end up working in the IT industry.
because IT uses a GUI, I could freely use a PC wherever I went
I thought that

However, after joining Beyond, I encountered Linux, an open-source system similar to macOS.
As a child, I loved computers, playing with them like a toy, so
I was confident I could do anything as long as the computer didn't physically break.
What I realized after joining Beyond is that my childhood thinking was indeed immature and limited.
I'm studying Linux with a slightly different perspective and approach than everyone else, while also learning commands useful for work.
Linux has become a great colleague for me because it allows me to communicate with servers.
Communication, whether with people or things, is important!

Here are some commands that I found useful:

1．yum install

This command can be used to install various applications on a server.
Note that the installation command varies depending on the OS.
Incidentally, the `yum install` command can be used on Red Hat-based operating systems.

# yum install [app_name] yum install httpd

2．systemctl

It controls the system or acts as a service manager.
[option]>>start, stop, status, enable, disable, restart…

# systemctl [option] command [name] systemctl start httpd

3. mkdir

The `mkdir` command can be used to create directories, or in more familiar terms, folders.
The great thing about `mkdir` is that it can create many directories at once.
`mkdir` also has options.

# mkdir -p mkdir -p [/tmp/com/us]

will create a directory that did not exist

mkdir /tmp/com/us

case, an error will be displayed because the directory /tmp/com does not yet exist.
In this

mkdir -p /tmp/com/us

Running this command will not produce an error.
This is because when the `us` directory is created, a parent directory called `/tmp/com/` is also created.

4. Touch and Cat

touch /path/to/file

The `touch` command updates timestamps. When executed on a file that does not exist, it creates an empty file to continue processing because the file whose timestamp needs updating does not exist.
`touch` can create files without a container.

# cat [file name] cat tee.txt

tee.txt is a file on my server, so please enter the filename on your own server!
You can use the cat command to view the contents of the file.

5. kill

The `kill` command is one of the commands you need to be most careful with.
It's like instantly eliminating a healthy process running on your computer.
In fact, the `kill` command is used to eliminate processes that are negatively impacting a server.
Just hearing the word "kill" is frightening, isn't it?

# kill [process name] kill httpd

lastly

I really struggled to get this blog up and running.
I think that's because I'm still in the process of learning Japanese.
I can speak my native Uzbek and English, but I feel that I still have a lot of studying to do to master Japanese, which is the third most difficult language in the world. I
my technical knowledge
will continue to study Japanese every day while also improving

This is the first blog post I've ever written.
The information I've written here may be simple and not very detailed for you, but even small things like this
are the first steps in my growth.
Over time, I will continue to acquire more knowledge and strive to write blogs that contain even better information for those who read them.
Thank you for reading.
