why does ./ not work as a directory? [Linux]

Question

I'm trying to install NET. 6.3 on my chromebook with Linux but when I try to execute

./dotnet-install.sh -c Current

in the Linux Terminal it always gives me this error:

-bash: ./dotnet-install.sh: No such file or directory

Any way around it/any fix for it?

I have done sudo -i so I got full permission and I have put the file I'm trying to execute in a lot of folders including my Linux folder.

Any help is appreciated!

Answer 1

I suppose you should:

chmod +x ./dotnet-install.sh
./dotnet-install.sh -c Current

or

/bin/bash dotnet-install.sh -c Current

Answer 2

There are two ways to execute a script on a UNIX/Linux platform:

• Either you make the script executable, as explained in the other answer.
• Either you use the sh or other relevant command for launching it, I prefer this way of working.

So, I would propose you to launch the following command:

sh ./dotnet-install.sh -c Current

Answer 3

Have you tried the pwd command to see on which path are you working on?
Then try to ls | grep dotnet-install in the current directory, if there isn't output you have to change directory.
Probably you are trying to execute the dotnet-install.sh in a wrong directory, i suppose.

Another way is to get file trough wget command on terminal to be sure you download the file in the correct directory.
