如何在bash脚本中查找冒号并将其替换为冒号？

Question

What I'm trying right now:

dir=$(pwd)
dir=${$dir//\//:}

But this isn't working for some reason.

The whole point of this is to convert a bash path to an applescript path, without hardcoding the path in there.

I'm essentially trying to do the opposite of this: https://apple.stackexchange.com/questions/4938/how-to-change-applescript-path-to-a-terminal-style-path

您的语法略有偏离，请不要在 ${}构造中的变量上使用$ ：

dir=${dir//\//:}
