Terminal always shows these extra lines after being opened

  • 772

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?

command-line

    enable is a Bash shell builtin command that takes/expects other shell builtin commands as arguments to list, enable or disable them ... You appear to have an uncommented statement/line like enable bash completion in interactive shells in one of the Bash Startup Files and that shouldn't be there ... Those startup files are sourced automatically every time an interactive shell is started (like when opening a new terminal ... mainly the files ~/.bashrc and, on Ubuntu, /etc/bash.bashrc for interactive non-login shells ... As well as any other files that are sourced in those files with . file or source file) and all lines in them are parsed and commands in them are executed in the current working shell unless a line is commented out by having # at its beginning ... Therefore, this might happen:

    $ enable bash completion in interactive shells
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
