ln has no destination. Check the arguments, or specify

ln /foo/bar/bazln "$file" "$dir"or
ln /foo/bar/baz .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 .
