How to create alias for a sub-folder to point to the parent folder?
I need to make a folder with name ./public/sop behave like it is ./public.
I tried ln -s ./public/ ./public/sop and there were no errors. But it doesn’t work. ls ./public/sop does not show the other files/folders in the ./public folder. It shows just one line:
lrwxrwxrwx 1 pi pi 9 Nov 20 13:06 public/sop -> ./public/
And an attempt to ls ./public/sop/test.txt, where test.txt is an existing file in ./public, returns No such file or directory.
How can I achieve what I need?
For this, you can use just . as the link target:
ln -s . ./public/sop
Then ./public/sop is effectively ./public/., which is just ./public itself.
You can see this in action in the Ubuntu repositories, where ubuntu is a link to ., so going to http://archive.ubuntu.com/ubuntu/ubuntu/ubuntu/whatever is effectively the same as http://archive.ubuntu.com/ubuntu/whatever.
