Bash输出：不是有效的标识符

我有Raspberry PI运行Raspbian。默认情况下，壳本身呈现鲜艳的格式化，我想改变一点点这些设置，操纵LS_COLORS变量，这样做：当我通过SSH登录Bash输出：不是有效的标识符

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

的问题提出。提示平时之前，显示此：

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

我在~/.bashrc和~/.bash_profile（实际上这一个不存在的话）看上去两者。我没有改变.bashrc中的任何内容，也没有直接指向LS_COLORS。我也尝试过$ unset LS_COLORS，但是在下次登录时没有任何变化。感谢您的帮助！

检查您的脚本DOS行结束。我怀疑你实际上是在试图导出'LS_COLORS \ r'。 – chepner

某处你有'LS_COLORS：' - 用冒号 –

任何想法在哪里看？ –

这行看起来腥：

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

确定要在EOL结肠？

其实这条线和整个'.bashrc'文件是Raspbian的原始文件。我没有编辑任何这些。 –
