Follow a file’s link and return the target file.
Limit the number of hops to make if there is a chain of links. By limiting the hops, you can get hold of any file in the link chain. You can also walk the link chain by always limiting the number of hops to 1.
Filter what link modes (link types) to follow. Use -1 to follow all link modes (to not filter what to follow). Use 0 to not follow anything. See link modes for more details.
Follow a file’s link and return the target file. You may limit what link modes to follow and after how many hops to stop. Following empty links is a no-operation, will return the file itself. Note that the link may be broken.
Example when no link is set up.
Currently you can only use links to import filesystems, which is not supported in this playground. Thus, it can not be demonstrated here.
For reference, here is how you would call follow by limiting the hops or filtering for specific link modes.
