如何获得一个具有当前目录路径的变量? [英] How to get a variable to have the current dir path?

问题描述

我在bash脚本中有一个非常简单的功能，可以告诉我当前目录.但是，它给出错误bash: =/home/users/abc: No such file or directory $ currentdir为空.

I have a really simple function in bash script that tells me the current directory. However it gives the error bash: =/home/users/abc: No such file or directory $currentdir is empty.

为什么会这样?我也尝试过

Why is this happening? I also tried

$currentdir=`pwd` 

那也行不通.

这是一个类似的问题， Bash:当前目录变量，我尝试了此操作，但并没有不能解决我的问题.

This is a similar question Bash: current directory variable and I tried this but it didn't solve my problem.

xpwd() {
    $currentdir=$(pwd)
    echo "current dir is $currentdir"
}

推荐答案

要设置变量时，请勿使用$:

When you want to set a variable, you don't use the $:

currentdir=`pwd`

$适用于要进行变量替换的情况.

The $ is for when you want to do a variable substitution.
