我收到“ bash：cd：参数过多”的信息，我不知道为什么？

问题描述

我正在尝试在我的终端（Ubuntu 20.04.1 LTS）上运行source .bashrc命令，该命令似乎可以正常工作，但我仍然收到错误消息：

bash: cd: too many arguments

我不确定这是哪里来的，为全面披露我的.bashrc是：

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

我的.bash_aliases是：

alias dev="cd ~/CRiiS/criisdev/"
alias test="cd ~/CRiiS/criistest"
alias criis="cd ~/CRiiS/criis"
alias live-web="ssh -T -tt live ssh live-web"
alias live="ssh live"
alias loc="cd ~/CRiiS/local"

但是，我不认为别名是问题，因为我已经从系统中临时删除了文件，并再次以相同的问题运行命令。

如果有人能为此指出正确的方向，我将不胜感激。

解决方法

test是bash内置的（[的同义词），因此您应该使用其他名称作为别名。

这在.bashrc的“启用ls颜色支持并添加方便的别名”部分中引起问题，该部分使用test -r ~/.dircolors && ...检查文件的可读性。
使用您的别名，它会扩展为cd ~/CRiiS/criistest -r ~/.dircolors，这会导致错误，因为cd仅接受一个非选项参数。

可以通过使用[而不是test（[ -r ~/.dircolors ] && ...）来解决此特定情况，但是您一定会通过遮盖内置内容而遇到更多问题。
