Hello brother, thanks for helping Us!!! I have a questions which was asked me in an interviewers? 1. How to reduce the size of 5gb docker image? 2. A file contains 100 lines or some lines. How to print some like servergyan data in a file on wherever or which line it is in that file?? 3. what is webhooks in git? 4. How to find a file in entire linux server without knowing any path details? We have only file name? 5. Write an Ansible playbook for downloading antivirus in 10 systems?

@ServerGyan 4 года назад

How to reduce the size of 5gb docker image? Copy only Required files in docker. Don't install additions software like vim nmap etc. Remove apt cache after installing software. Don't run apt-get install multiple times (but mentions all required package in one command) A file contains 100 lines or some lines. How to print some like servergyan data in a file on wherever or which line it is in that file?? grep -r root /etc/passwd what is webhooks in git? This is used to trigger an event-based Jenkins build. How to find a file in entire linux server without knowing any path details? We have only file name? Use can use:_ locate filename If locate command is not available you can use yum install mlocate -y ; updatedb Ansible playbool I will explain in some videos

Disk space is still full even after deleting a file of 5GB? i did not understand the explanation of this question

@ServerGyan 3 года назад

If a file is being used by any process and you delete it, operating system doesn’t release the disk space. In order to reclaim the space you need to figure out the file and service Then you can get space back

Dear srikanth, Next video is coming today

@cutting-edgehub5360 Год назад

I have observed in most of your videos, either you simply skip few questions without even touching them or even if you touch them then you don't elaborate properly at all. In this video also you didn't speak about the question# 9,10 and 11 from the top. This is very disappointing. If you didn't have to elaborate them then why did you put them in the list ?? This is very frustrating and utter time waste that i have to google them separately. This is not about this video only. In most of your videos you have done such things..
