and when i type: ./my.sh

it shows: -bash: ./my.sh: bin/bash: bad interpreter: no such file or directory

it would be great if you can help me thank you very much

You've not provided any OS & release details; and your script doesn't have a shebang that tells the system what type of script it is, and what interpreter/shell to use to execute it with. Did you make it executable? — guiverc, Dec 08 '21 at 10:30
It looks like your script is not just echo "hi", but has a #! line - which is incorrectly written with a relative path #!bin/bash instead of absolute path #!/bin/bash — steeldriver, Dec 08 '21 at 12:40
Does this answer your question? bin/bash: bad interpreter: No such file or directory — karel, Dec 09 '21 at 03:17

Three things:

Why the sudo? At this point, you do not want to run your script as root.
All your scripts need to start with the interpreter on the first line It's the comment sign followed by an exclamation sign. (The "Shebang") For bash, your script would look like this:

#!/bin/bash

echo "hi"
You should make your scripts executable with chmod 700 myscript.sh. Only then can you execute them like this ./myscript.sh

On a related note, this is not specifically a Ubuntu question, but a generic scripting question.

i did use Shebang sorry i didnt not mention. In addition i also gave the right permissions. Thank you for your answer – Yarin Levy Dec 08 '21 at 10:55

Using chmod +x instead of chmod 700 wouldn't affect read and write as well as group/other permissions – pLumo Dec 08 '21 at 13:50

/usr/bin/bash $HOME/my.sh

Try this and see the difference, you probably are not in the right directory to execute a file. cd or pwd and ls to make sure what you are doing.
