Create a Symbolic Link on an SFTP Server

See more SFTP Examples

Demonstrates the Chilkat SFtp.SymLink method, which creates a symbolic link on the server. The first argument is the link target and the second is the new symbolic-link path.

Background: A symbolic link stores a path that points at another location, so it can span directories or filesystems and can even point at something that does not exist. A common use is a stable name like latest.log that is repointed at each day's file. Argument order is a frequent source of confusion — the target comes first, the new link path second — and note that how the target string is interpreted (relative to what) is up to the server's implementation.
