Just a quick note for everyone: USR is not actually "user" and does not contain users like the windows directory does. It stands for Universal System Resources, containing various stuff for all user programs, but the actual "user" directory is "home" for non-administrative users where as the root users or super-admins are located under "root".

I don’t believe this to be completely true, and I thought the actual saying was UNICs system resources before Linux and that the original intention was to have user system resources under usr. So essentially usr doesn’t mean anything and people can feel free to call it The User directory

cd ~ is unnecessary, just 'cd' will change to the home directory. cd - will go back to the previous directory, it probably reads the env var $OLD_PWD to do so. Also, if you only partially remember the name of something you can use file globbing to change to it. This is an example: cd music/bands/u2/albums/*tree/

wonderful con-sized video for quick learning.
Thank you i learn a few new things
Good Information in this video for beginners I appreciate your hard working
Good job.. a very useful (but also dangerous) command is "dd" which just moves data, (entire or partial data from files etc), Very useful if you want to clone a hard drive - example (sudo dd if=/dev/sda of=/dev/sdb) this would clone the entire drive (where "if=" is the input file and "of=" is the output file). You can also designate how much data to move per cycle - the default is 512 bytes but you can designate something like bs=1M where it would move 1 megabytes per read/write.. Just to be on the safe side - boot a linux thumb drive so that none of the drives being used in the cloning process are active or mounted (not really necessary but just an added precaution).. Just make sure that the drive being clone is smaller than the target drive (resize partitions prior to cloning) or the target drive may run out of space..
Subscribed due to good content and also good presentation
best illustration of linux commands.

Hey Vineet, this is good video to starters with Linux. its quite useful as easy language and good visual practicals.can you also share link for the next step video after these commands set?
excellent teaches thanks a lot sir by C TAMILMARAN
authentication failed when i try to be a root user,i am putting the right password,what can i do?
How can I add a Shared partition that Anbox can access?
thanks for the Video, good guide. just some thoughts if you don't mind. mnt is not necessarily where the system mounts removable media, this depends on the Linux flavour, e.g. Arch uses /run/media, for removable devices, others may use /media usr = Unix System Resources etc = Edit To Configure 'su root' only works when the root account is enabled, it's disabled by default in Ubuntu as it is in most Linux flavours. Just want to point this out as well as it isn't deemed as secure to enabled root and in most cases not necessary, 'sudo su' is preferred and the users password is used instead of the root password.
Nice one thanks making short and sweat

Nice video
Nice video. Please zoom in more in next video. It's tough to focus when watching on mobile.
There's really only one thing that I can think of that I've gained from this. Since I mostly been using windows, and I'm starting to get use to Unix like systems through Cygwin. I wrote a small program in C to use GNU's MPFR library to test it out. After successfully being able to compile and link the test program with their libraries and the executable is created; if I just try to run the program in the Cygwin (mintty) shell as such: "test" or "test.exe" I did not see any results from the Cygwin terminal. However if I opened windows cmd prompt or windows file viewer and navigated to this directory; I could either double click the exe icon or type it out in cmd and it would run. So back to the one thing that I did gain from this video when working in the Cygwin terminal is that for any C/C++ program that I build; if I want to run it through the terminal I can not simply just type the name of that program because its executable or binary is not in the $PATH environment. I would then have to use "./program_name" instead.
I found it quite good so far. I am a beginner and wanna learn Linux for better job.
Can anyone provide me solution to this please.. Thanks in Advance!! My ubuntu 18.4 LTS freezes while installation .. after trying hard, I was able to install it .. did sudo update and upgrade too but i am seeing that after few minutes everythhing freezes and get stucked.. I have to do a force restart everytime.. just for information - I am using gigabyte 250 motherboard, 16gb single RAM, 2 TB harddisk and a good circle stick cabinet .. I already have Ubuntu installed in my older systems and they never showed this problem..
Great.. Really Nice Content in the video..
