Having been in this situation (the only binary I could use was bash, although cd was a bash builtin for me), echo * is your friend. Even better is something like this:

get_path_type() {
    local item
    item="$1"
    [[ -z "$item" ]] && { echo 'wrong arg count passed to get_path_type'; return 1; }
    if [[ -d "$item" ]]; then
        echo 'dir'
    elif [[ -f "$item" ]]; then
        echo 'file'
    elif [[ -h "$item" ]]; then
        echo 'link'  # not accurate, but symlink is too long
    else
        echo '????'
    fi
}

print_path_listing() {
    local path path_type
    path="$1"
    [[ -z "$path" ]] && { echo 'wrong arg count passed to print_path_listing'; return 1; }
    path_type="$(get_path_type "$path")"
    printf '%s\t%s\n' "$path_type" "$path"
}

ls() {
    local path paths item symlink_regex
    paths=("$@")
    if ((${#paths[@]} == 0)); then
        paths=("$(pwd)")
    fi
    shopt -s dotglob
    for path in "${paths[@]}"; do
        if [[ -d "$path" ]]; then
            printf '%s\n' "$path"
            for item in "$path"/*; do
                print_path_listing "$item"
            done
        elif [[ -e "$path" ]]; then
            print_path_listing "$path"
        printf '\n'
        fi
    done
}

This is recreated from memory and will likely have several nasty bugs. I also wrote it and quickly tested it entirely on my phone which was a bit painful. It should be pure bash, so it’ll work in this type of situation.

EDIT: I’m bored and sleep deprived and wanted to do something, hence this nonsense. I’ve taken the joke entirely too seriously.

… but cd is a built-in

Reminds me this great story from a different era:

Hmmm command not found, let me just try the same command a couple more times, this time it will work right?

In IT teaching users to actually read and understand errors is always an uphill battle.

bah, https://github.com/fosslinux/live-bootstrap

you don’t even need a terminal or a prompt to bootstrap every tool you need.

I see girls last tour, I upvote.

echo $PATH

And alias to be sure.

Empty $PATH.

sudo dd if=. /rpi3-aarch64-archlinux.img status=progress of=/dev/sd[tab] [tab] [enter]

I remember being so scared the first time I screwed up my $PATH

This isn’t programming, just someone who sucks at bash.
