Please be kind to the Linux O&M engineers around you, because they

 

When it comes to Linux O&M engineers, I believe many people will have these words in their minds: low EQ, unromantic, stupid, silly, and unable to find a girlfriend

(The last one is not what I said. Don't beat me.) In fact, most Linux O&M engineers are extremely humorous and honest!

In the face of dark work, they can concentrate on completing every task assigned by the leader;

In the face of boring work, they can occasionally laugh and tease to give you a look back;

Faced with a long single life, they can live and die with all kinds of dead servers and data;


If you have friends with Linux O&M engineers, your daily conversation should be as follows:

A: Where is your address?

Linux operation and maintenance engineer: enter ifconfig - a command in the terminal and press Enter.

A: I said your coordinate address?

Linux operation and maintenance engineer:

(1) Get the pid of the process, and then use the command ls - l/proc/${pid} to list the start location of the process.

(2) /usr/sbin/lsof | grep ${process name} This command can also list the start location of the process.

A: Crazy! I mean your local address?

Linux operation and maintenance engineer: Ioctl() Get the local IP address

A: I mean, where does your family live

Or:

A: Do you know why Kobe was successful?

Linux O&M Engineer: Why!

A: Have you ever seen Los Angeles at three in the morning?

Linux operation and maintenance engineer: At that time, I was forced to maintain the server. How could I know.

A: All right


There are also:

One night, the female boss asked the programmer, "What do you want to do most if you can fulfill your wish?"

The Linux O&M engineer said, "Let me take a bath and have a good sleep."

Then the female driver shyly sat next to the Linux O&M engineer, getting closer and closer

The programmer asked in a daze: Is there something wrong with my server?

So the female boss said, "You'd better continue to work overtime...."

If you have friends with Linux O&M engineers, you will find that their daily work is as follows:

They work overtime as follows:

Their ideal is as follows:

However, the reality is as follows:


Well, I hope you can thank these great Linux operation and maintenance engineer , let's enjoy the Internet.

If you also have a friend who is a Linux O&M engineer,

Please be sure to tolerate and understand him,

He may not have so much time to accompany you,

There may be no holidays,

You may not have time to answer the phone,

Because he has been studying various machine failures.

If he gets angry for no reason,

Please understand him and don't argue with him,

Because he may be criticized by the leader.

If he says he wants to rest, please don't disturb her,

Because he may have been busy all day.

In short, if you find a Linux O&M engineer as a friend,

Please love her well,

Because he is really not easy.

Do you have any friends who are Linux O&M engineers?

What is their life like?

Let's talk about it together!

 


Finally, I prepared a necessary "weapons warehouse" for operation and maintenance for all the big men and dear doors. It is said that this weapons warehouse can get a high salary of more than 30k when it is available. I was dazzled and said yes..
