How to revert a shell command? Overwritten the "pwd" command

Question

After typing "pwd" in shell you normally get the path to the current working directory. However, if you type "pwd()" instead, you get a message [function>] after which you can type anything (eg: echo hi; ls -laR).

Now executing the "pwd" command will no longer print the current working directory, but instead it will execute the user input every time.

My question is, how do I revert this behaviour? Thanks!

Answer 1

Have you tried to restart Bash? If that doesn't work you can use unset -f pwd remove the function.

Answer 2

by doing pwd(), you are creating a shell function.

Get rid of it by:

unset pwd
