Analogue of NotebookDirectory[] for scripts (to get the directory path of my script.m)?

Question

Is there a way to get the script directory from inside a Mathematica script?

I want a function analogue to NotebookDirectory[] (which doesn't work for scripts). Is there a way to do this?

DirectoryName @ $InputFileName

is the answer, right?

And this will work whether you call it from a package or a notebook interface:

parentPath = $InputFileName /. "" :> NotebookFileName[]
parentDir = DirectoryName @ parentPath

Check:

path = FileNameJoin[{$TemporaryDirectory, "test.m"}];

Export[
 path,
 "Print @ DirectoryName @ $InputFileName",
 "Text"
 ]

Get @ path

$\begingroup$ sorry, but this doesn't work if you call your script (.m) from within the terminal using wolframscript $\endgroup$ – Santiago Aug 22 '17 at 13:31
$\begingroup$ @Santi could you elaborate, with a script.m file containing only: Print["test parent dir: ", DirectoryName @ $InputFileName] I get: i.stack.imgur.com/SrLrA.png $\endgroup$ – Kuba♦ Aug 22 '17 at 13:41
$\begingroup$ hi @Kuba, ok, you are right, but in the way I was running my scripts it doesn't work. If I do: wolfram -script script.m it works. But if I do wolframscript -file script.m it doesn't work. I am on Mathematica 11.1.1 Kernel for Linux x86 (64-bit). $\endgroup$ – Santiago Aug 22 '17 at 14:29
$\begingroup$ do you have an idea why this doesn't work with wolframscript ? $\endgroup$ – Santiago Aug 23 '17 at 8:31
$\begingroup$ @Santi I didn't work with scripts yet so I don't know, I will try to investigate if I find time. You could ask a question on main about that. Just make sure to prepare simple example people can run. $\endgroup$ – Kuba♦ Aug 23 '17 at 8:33
