Mastering 4 Essential Linux Utilities - awk, sed, grep, find

Linux utilities summarized in one lecture
Learn commands easily with practice.

Linux, how to use it properly
You absolutely must learn the commands!

Do you know the prune feature of Find?
Have you ever seen Permission Denied often when searching for Find?

Aren't you just using find or grep as simple file or directory search or string search tools?
If you remember searching the Internet because you didn't know how to use the find or grep commands, this lecture may be helpful.

• This course is a sequel to the Linux Shell Script Master course.
• After taking this course, your Linux skills will take flight.
• Want to learn how to use Find or grep better? Here's how.

Linux Commands , Why Are They Important?

A significant portion of what we do with computers usually involves tasks like this.

• Find data on your computer
• Editing documents (sed, awk)
• It's about finding (grep) something within a document.

Why are grep, find, sed, and awk important in Linux? Because these tools are directly related to the tasks mentioned above.

Since the above commands are frequently used commands, hackers have inserted dozens of usage methods into these commands as options. Therefore, users need to learn these commands separately from other Linux commands. ^^

However, information about Linux grep, find, sed, and awk on the Internet is quite fragmented. When searching for how to use a command, even if you find a single sample example, it is not easy to rewrite it.

Save your time!
Linux can be used 'better'.

There is one more reason why this course is necessary.
Let's take an example using the Grep command. Do you know what the -P option does? I know that many people who know how to use the Grep command have searched on Google or Stack Overflow.

Why is that? Isn't it because I don't remember or don't know the various grammars, such as the options or regular expression patterns that I use in the search I want to use? This is the problem that Google searches waste a lot of time like this.
Even Linux system server administrators say that they have a hard time remembering the options of commands that they don't use often. I think that this statement reflects the difficulty of Linux commands and the need for learning .

There are actually hundreds of Linux commands. If we were to list only the most frequently used ones, there would easily be 30 of them. The Find command alone has 30 to 40 options.
If so, a systematic approach is needed for this part.

4 essential Linux commands
Easier, more powerful.

I can't guarantee that you will become good at Linux right away just by taking my lecture. However, at least your basic Linux skills will definitely change before and after taking the lecture.

Why are books like sed & awk sold on Amazon?
Simple use would be no problem, but if you try to use it 'well', doesn't that mean there's a lot to study?

There is no more detailed find/grep/sed/awk course online or offline than this. It will upgrade your command utilization skills to the next level!

Recommended for these people! 🔑

Linux server system administrator who uses a lot of Linux commands

DevOps and full-stack developers who require proficient Linux usage

Those who only use find or grep as simple file search or string search tools

This will also be helpful to those of you who are fairly good at using Linux!

Besides that, it would be good for people like this to learn too!

• 👉 Linux-based AI, autonomous driving software developer
• 👉 If you are using a terminal program on a computer based on Apple Mac OS
• 👉 Those who develop kernels and drivers in embedded Linux environments
• 👉 College or graduate students who need prior learning about the Linux environment
• 👉 People who use Linux environment in fields such as medicine, engineering, etc.
• 👉 Those preparing for the Linux Master Level 1 and 2 exams

After mastering Linux shell scripts
An ambitious new work released after two years!

This course is a sequel to Inflearn's popular course , Mastering Linux Shell Scripts . I launched this course based on the fact that surprisingly many people repeatedly search Google whenever they use the Linux commands find and grep. I am confident that if you organize the various options of the commands systematically, you will be able to use simple ones without having to search the Internet later.
