SC2226

This ln has no destination. Check the arguments, or specify . explicitly.

Problematic code:

ln "$file $dir"

or

ln /foo/bar/baz

Correct code:

ln "$file" "$dir"

or

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.
