错误:$(.)中的修饰符 [英] Bad : modifier in $ (.)

问题描述

我想在linux中设置环境变量，并通过给出命令进行相同操作

 export PATH=$PATH:.

但是遇到错误Bad:$(.)中的修饰符.

有人可以帮忙吗? 我尝试了bash shell和ksh

解决方案

Bad : modifier in $ (.).

这不是 Bash 错误，也不是Ksh :它来自C-shell或其克隆之一，例如 Tcsh .

您想要:

setenv PATH ${PATH}:.

但是您不应该在${PATH}中放入.，这是众所周知的安全风险.

I want to set environment variable in linux and did the same by giving command

 export PATH=$PATH:.

But getting error Bad : modifier in $ (.).

Can some one help this. I tried with bash shell and ksh

解决方案

Bad : modifier in $ (.).

This is not a Bash error, nor is it from Ksh: it's from C-shell or one of its clones such as Tcsh.

You want:

setenv PATH ${PATH}:.

But you should not put . in your ${PATH}, it's a well-known security risk.
