  • tab completion being overenthusiastic

    From Eben King@21:1/5 to All on Sat Sep 7 15:00:02 2024
    Hi. I have bash 5.2.15(1). When I cd into an empty directory, and type "cd <tab><tab>", the shell offers 178 possibilities. If I restrict it to an initial letter and hit <tab> once, I think the spurious offerings are from $HOME. How can I make it not do that and only offer me things I ask for?

    Do you perhaps have the CDPATH variable set? That might affect tab
    completion for the cd command.

    eben@cerberus:~$ echo "$CDPATH"
    :~:/

    0
    eben@cerberus:~$ grep CDPATH /etc/profile /etc/profile.d/* ~/.profile ~/.bash_profile
    1
    eben@cerberus:~$

    In fact I do. Good catch. Any idea where it could be set, other than the places I looked?

    Got it. It was in ~/.bash-vars which was sourced from ~/.bash_profile . Is that a standard thing, or just some "brilliant" idea I had once upon a time?

    It's not a standard file.

    By the way, there's a trick you can use to find out where shell variables
    are being defined:

    PS4='+ $BASH_SOURCE:$FUNCNAME:$LINENO:' bash -ilxc : 2>&1 | grep CDPATH

    The -il options run an interactive login shell. If you need to check an interactive non-login shell instead, just change the options to -ixc.

    This won't work as root, because PS4 from the environment is suppressed
    for security reasons when running bash as root.

    Excellent, thank you.

    Nifty! Thanks for this one.

    If you mean the file itself, you might try stat ~/.bash-vars
    and looking at the Birth date; then you could check out your
    Sent Mail folder and see whether you were discussing anything
    relevant around that time. Other places that might help are
    your browser's history, and the index for debian-user.

    Cheers,
    David.
