GitHub Actions workflow syntax not working as expected

Question

I have a GitHub workflow that is triggered when files according to the pattern **/abc** are modified / created. As far as I understand it, this means that whenever a:

1. File that is in some subfolder of a folder that starts with abc or
2. Any file that starts with abc

is modified, the GH action should be triggered. However, the workflow is even triggered when I eg create a file repository/aaa/test_abc

However, to my understanding, the file repository/aaa/test_abc does not correspond to the pattern **/abc**

Do I

1. Misunderstand GH actions syntax or is it
2. A Bug in GH actions?

Answer 1

You need to escape the / with a \ for the pattern to work.

Using '**\/abc**' will resolve the problem.

Most of the time, the filter pattern cheat sheet for the Github Documentation helps to configure the paths, but in that specific case it wasn't detailed.
