How to get a variable to have the current dir path?
提问by saksham bhatla
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$currentdir is empty.
我在 bash 脚本中有一个非常简单的函数，它告诉我当前目录。但是它给出了错误bash: =/home/users/abc: No such file or directory$currentdir 为空。
Why is this happening? I also tried
为什么会这样？我也试过
$currentdir=`pwd`
and that didn't work too.
这也不起作用。
This is a similar question Bash: current directory variableand I tried this but it didn't solve my problem.
这是一个类似的问题Bash: current directory variable，我试过了，但没有解决我的问题。
xpwd() {
$currentdir=$(pwd)
echo "current dir is $currentdir"
}

When you want to set a variable, you don't use the $:
当你想设置一个变量时，你不要使用$：
currentdir=`pwd`
The $is for when you want to do a variable substitution.
的$是，当你想要做一个变量替换。

Assigning to a variable is without the '$' sign. Using the value is with the '$' sign.
分配给变量没有“$”符号。使用该值带有“$”符号。
currentdir=`pwd`

try:
尝试：
currentdir=`pwd`
(remove the $)
（删除$）
