You might want to try this:
你可能想试试这个：
export PATH="${PATH}:."
I don't like having the current directory in the path, but at the end it's fairly safe.
我不喜欢在路径中包含当前目录，但最终它是相当安全的。

Bad : modifier in $ (.).
This is not a Basherror, nor is it from Ksh: it's from C-shell or one of its clones such as Tcsh.
这不是Bash错误，也不是来自Ksh：它来自 C-shell 或其克隆之一，例如Tcsh。
You want:
你要：
setenv PATH ${PATH}:.
But you should not put .in your ${PATH}, it's a well-known security risk.
但是你不应该把.你的${PATH}，它是一个众所周知的安全风险。
