+## This ln has no destination. Check the arguments, or specify '.' explicitly.
+
+### Problematic code:
+
+```sh
+ln "$file $dir"
+```
+
+or
+
+```sh
+ln /foo/bar/baz
+```
+
+### Correct code:
+
+```sh
+ln "$file" "$dir"
+```
+
+or
+
+```sh
+ln /foo/bar/baz .
+```
+### Rationale:
+
+ShellCheck found a `ln` command with a single parameter. This may be because the source and destination was accidentally merged into a single argument, because the line was broken in an invalid way, or because you're using a non-standard invocation of `ln` that defaults to linking the argument into the current directory.
+
+If you wanted to specify both source and destination, fix the `ln` statement.
+
+If you wanted to link a file into the current directory, prefer using the more explicit and POSIX standard invocation `ln /your/file .` 
+
+### Exceptions:
+
+None.
