Hey, everyone.
Welcome back to this video.
So the next directory that we are going to see is slash Etsy.
Now, this is a very, very important directory for any Linux operating system.
Why?
Because this contains configuration files which are required by the system to run.
Now, this directory contains the configuration files which can generally be edited by hand in any text
editor of your choice that can be either vim or nano.
One thing that you should note over here that the ADC directory contains system wide configuration files
that are required by the system, and users can also modify and edit those specific configuration files
according to their needs.
So each configuration file is located in each user's home directory as well.
Or in case you install any programs into this computer, the configuration files lies into those directories.
For example, if you install Apache to web server, the configuration file will lie into slash etsi
slash apache two slash apache conf.
So I hope you guys understood why ETSI is used.
So let's jump on to the practical time and let's see this in action.
I'm onto my terminal and let me just navigate quickly to the ADC directory and you can see I am into
the directory which is ADC with the help of the command that is PWT.
Let me just hit list and you can see all the system level commands are over here.
For instance, you can see pass WD or maybe you can see user add command as well.
Here you can see VSA, FTP conf, which is the configuration file for FTP service that is been running
into this computer.
Let me also show you MTP icon, which is the network time protocol configuration file which has been
installed into this computer.
Similarly, you can find sudo as file user add, etc..
So I hope you guys understood the system level commands that you run into your computer.
The configuration file lies into the ADC directory, hence it is considered to be very important.
And one note that you should not edit or delete any system level configuration files over here so that
you do not mess up anything into the system.
So I hope you guys understood.
Thank you.
