我有一个运行 Raspbian 的 Raspberry PI。默认情况下，shell 呈现出彩色格式，我想通过以下方式更改这些设置，操作LS_COLORS变量：

LS_COLORS="ow=01;90:di=01;90"
export LS_COLORS

当我通过 ssh 登录时出现问题。在提示通常之前，它会显示以下内容：

-bash: export: `LS_COLORS:': not a valid identifier

我已经查看了~/.bashrc和~/.bash_profile（实际上这个不存在）。我没有更改 中的任何内容.bashrc，也没有任何内容直接指向 LS_COLORS。我也尝试过，$ unset LS_COLORS但在下次登录时没有任何变化。谢谢你的帮助！

.bashrc以供参考：

# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

这条线看起来很可疑：

test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)":

确定要在 EOL 时使用结肠吗？
