I am using Kubuntu 22.04.3. Whenever I open the terminal (or konsole), the following five lines are always displayed.
bash: enable: bash: not a shell builtin
bash: enable: completion: not a shell builtin
bash: enable: in: not a shell builtin
bash: enable: interactive: not a shell builtin
bash: enable: shells: not a shell builtin
I am not sure what these lines mean. Am I doing something wrong?
