man i love you so much youre such a great teacher i spent like 10 hours learning bash but couldnt understand it but i understood everything you taught and it was very easy to digest and process. thats a lot

I went through the entire playlist in one and half day, practicing along on the side. I am not sure how confident i am at this moment but i have learned a lot. Thank you so much. Subscribed and looking forward to other tutorial videos. P.S - can you make more vids on networking and network troubleshooting.

Well, I started kind of late with the terminal but I would like to thank you for the content you provide here . Your explanation is exceptional. Thank you so much. God bless.

I got some error while copied and ran your script of first example , i.e. comparing args number. then I realized that in the video $ was missing while calling the variable "NUM_REQUIRED_ARGS" in if condition - happy to to the troubleshooting .yay ! thanks for the nice videos :-)

This is great! I am learning a lot and automating a lot of the things I have done manually for years

As always, another great video! Maybe somewhat outside the scope of the video, but I missed the use of exit codes to break out of a statement under certain conditions, especially with longer (nested) conditions. This would really make it complete, but this “exit code topic” is already worth a video itself. Again, your videos are always of a distinctively higher level. Always very complete and well argued and explained. Thanks for that!

Hey this is a great callout, thank you! And I really do appreciate the kind words

Very nice! I am waiting for the next lesson! Thanks, man!

Thanks these lessons were extremely helpful.

Good job!.This helps me a lot. But I have some questions. In the line [ "$NAME" = "Dave" ] ,I can't understand why there need " " for the $NAME. So I also tried [ $NAME = "Dave" ] Both give me the same output. So I think maybe the " " for the variable is not necessary?

Did you run the script with an argument? If it's displaying the output without an argument specified on the command line, then that means the syntax is broken, the script is ignoring the actual test and is just skipping to your output line and running it. Quotes around the variable are required in order to compare it to "Dave" as a string.

Hey, I've realized the syntax in this tutorial is a bit outdated but it's nothing that's beyond a simple google search.

Thanks a lot!

is there a difference between echoing the text result of a command with backticks compared to with parens?

could you explain the difference between $(var_name) and ${var_name}? Thank you

I punched in the code that checks the number of arguments and it looks like it will print "Call this script with ./{./test.sh}

I keep getting syntax error after using ";" then I changed to ":" Next I got; unexpected end of file

I solved it, God Bless Stack flow I removed the ":" and also gave space for [ $NAME="Dave" ] and, used exit $? for end of code then is in a new line . if [ $NAME="Dave" ] then echo "Dave" fi exit $? God bless Stack flow I use ubuntu

Don't we require a $ before NUM_REQUIRED_ARGS in line 9 to access it?

I am struggling to understand the idea of portability... What is it in a nutshell?

If your script runs with zero issues on your Linux box, that does not mean that it will run issue-free on some other Linux distro. This is more likely to happen if you use features that your more modern, up-to-date box has, and then you copy your script to a different, older distro. So if there is a chance that you might ever need to copy your script to other boxes (i.e., you want your script to be portable, to be used elsewhere), then avoid using coding that might be problematic for older distros.

It's been a while. Is it still a good idea to go with the old [] syntax rather than the new [[ ]]?

Doubles are preferred now for test, I think! They were even when I made this video but I had been working with some legacy code when I made it, haha.

Can you please provide source code for this video?

Very difficult to work with this video on first run through due to hidden code

I don't know why but this feels like it should be illegal. I worked with more than 5 language c cpp java js python etc still. even PHP has some what ok ish syntax but this is hard to swallow for me. the syntax just feels odd, why cant they adopt more standard C like syntax.

You didn't really cover $(ls nonexistentfile). I get that you're somehow executing ls but previously you said that we should use backticks for executing other commands inside the script. What exactly is happening here?

You can use backticks ``, but $() is just more convenient to execute commands.

Very difficult to work with this video on first run through due to hidden code . Lots of "unexpected end of file" messages because the end of the .sh script isn't shown to the viewer until very late in the video. This is not your best work, at all.

I don't see how any amount of research is going to clean up the presentation concern that I expressed. Perhaps English is not your first language. Can you be more clear?
