I'm trying to learn Linux essentials on WSL. I tried to change permission for a test file and it didn't work as I expected.
$ stat test.sh
File: test.sh
Size: 1616 Blocks: 8 IO Block: 4096 regular file
Device: eh/14d Inode: 93168217291239796 Links: 1

$ chmod 444 test.sh
$ stat test.sh

As you can see, I tried to apply the permission 444, here 555 was applied. Another example,
$ stat test.sh
File: test.sh
Size: 1616 Blocks: 8 IO Block: 4096 regular file
Device: eh/14d Inode: 93168217291239796 Links: 1

$ chmod 711 test.sh
$ stat test.sh
File: test.sh

Which, again you can see, doesn't work correctly.
I looked at this question but it didn't help me. I found a similar post (as my machine uses NTFS partition and the file is inside /mnt) on AskUbuntu but I found it too complex for me.
