I was anxious about learning bash CLI. You've made it a breeze. Very clear and concise, excellent delivery. English is perfect. Well done, now I continue.

Thank you so much!! My professor only teaches up content from a separate textbook, while we have to teach ourselves this content. Although it is a 100 class, it has been the most difficult for me because of him not teaching us this content and instead focusing on understand the history of computers, which I get is a major part of the curriculum but when our labs are based off of being able to work in Linux, it get difficult. Not to mention that the understanding computers part is weighed much more than these labs, especially with the chapter quizzes that have nothing to do with linux.

At 8:01 appending doesnot give same result as check...it returns list1.txt twice

[willh]

Good videos, pretty easy to follow. Just wondering if anyone noticed the output of combining the files at 7:55 was off? Could just be me as I am still a beginner, but why is there no "list 2 line 1" in the output?

[adeelmalik]

Hello sir can i remove duplicate records . if i am appending both file if both files have same data it write it once ?

[sarwatw]

Hello,
Was there any changes to list 2 file as append command ( cat list 1 >> list 2 ) output shows same file contents.

[satyashivam]

cat > <filename> to over write to file if it is existing or create a file and write in it.
cat >> <filename> to append content in that file if the file is existing otherwise give error that directory not found.
cat <filename 1> <filename 2> >> <filename 3> this will combine content of filename 1 and 2 and append in filename 3.
These command are not just for cat but we use any command and store content from that command using > and then add file name .

[johnr]

Is there a way to shorten the prompt? It's taking over half the line, making your sample commands hard to follow.

the second cat of line 4 5 6 is deleting the first of 1 2 3 why?

[kayteevsvp]

sir i watched your how to install java video and java home but when i did every thing in the video i still cant open any files with java it doesnt show up can you please help? im on windows 10 and im trying to open a .jar file

[IamAWESOME]

Why do this when you can use nano or any terminal text editor?

[hamsterlivegaming]

At last
cat list1.txt >> list2.txt
will return the content of list1.txt twice into the list2.txt, instead of merging them.
Please correct

[sadrulquadri]

I want to append the contents of list1 to list2 but I want the contents of list1 to written first and then list2.
How do I do that??

[pcriginal]

how to undo when use this command "cat > test101"

[anuragsmusic]

for those who observed the result at 7:55
Actually the Command
cat list1.txt list2.txt > list2.txt
will copy the content of list1.txt to list2.txt instead of merging them.

So, then content of list2.txt becomes
list1 line1
list1 line2

list 1 line 3

and then author again wrote the command
cat list1.txt >> list2.txt

So, the content of list1.txt is now appended list2.txt content, which already what I have shown above.
That's why we are getting that output at 7:55.
I hope issue of many will get resolve after this.
