Good day. Is any one able to help me with Mac terminal? I guess i have done something that is affecting it, as it is stuck and i cannot even type anything in it

Is the "source ~/.bash_profile" line contained within this file or did you issue the command within the terminal itself?

If you put this line in the "~/.bash_profile" file, then you are going to cause a recursion type loop that will never finish. You will need to quit the Terminal app and edit the file using TextEdit or by booting into Recovery Mode to edit that line out. Also using the tilde in a script is not a good idea. In a script if you want to indicate the home folder, then use "$HOME/<rest-of-path>". FYI, the "~/.bash_profile" file is a script.

What isn't typing? If you are typing your password it is not echoed when you type. So that is normal behavior. You need to provided more details if the problem is not related to typing your password.

It sounds like you just need to open a new window. In Terminal, go to the "Shell" menu and choose "New window" > "New window with profile - basic".

However, there is no guarantee that will work. The commands you entered were wrong. I think you may have gotten lucky this time. You shouldn't have used the "sudo" command for this.

Otherwise, without knowing exactly, and I mean precisely, what you did, down to the individual keystrokes, there is no way to tell if your change worked or if your Terminal will work in the future.

Start by opening a new Terminal window. See if your new Terminal window works as it did before. Then see if terraform is now in your path and you can launch what ever it is. Reply back is anything is amiss.

It would help us help you if you provided details such as what model/year Mac, what operating system version, what commands you entered.

We would need to know the exact commands you were using.

FYI, you should not just blindly enter (or copy & paste) commands you find online. Many times those commands will need to be customized for your system anyway. The command line offers you no protective safety net like the macOS GUI does. You can easily break macOS and destroy all your data if you are not careful. Sometimes just simply typing just one wrong character is enough to make a good command bad.

You should be able to use Control + C to terminate the process you started. If not, then just close the Terminal app. Try rebooting the Mac.
