You should use working directory of the custom action's process, which is always the path of repository

[heartacker]

we just want the folder name, the folder name is fix and part of path, dirname remains unchanged, just like path, and we also need to use dirname for better processing please

[heartacker]

I know the path is fixed, but I only need the name of the folder. And this folder is fixed just like the path, which is very useful for custom processing. I need to get the name of the folder instead of the name of the path

DIR_NAME=$(basename `pwd`)

[heartacker]

it can not work in action command,

DIR_NAME=$(basename `pwd`)

It's a shell expr. You should use echo "$(basename `pwd`)"

That is to say, even for further customized requirements, even if they are simple, I have to use the shell. Moreover, under different operating systems, such as Linux or Windows, I also have to write specific and different commands for the operating systems to achieve the same function.
