[gj52]

What version of Hugo are you using (hugo version)?

$ hugo version 0.93.2
works with 0.93.1 !

Does this issue reproduce with the latest release?

YES

---

Dev on Windows is fine. Prod on Linux breaks, can not find file or directory

path is assets/etc/apache2 with some copied conf files from /etc should find apache2.conf

shortcode is

{{ $filepath := printf "/assets/etc/%s" $path }}
{{ $files    := readDir $filepath }}
{{ $ext := default "-" (.Get "type" )}}
{{ if (fileExists $filepath)}}
<div class="pa2 mh4 ba">
{{- range $files }}
    {{ if (and (ne (substr .Name 0 1) "_") (not .IsDir)) }}{{ $f := resources.Get (printf "etc/%s/%s" $path .Name)}}
        {{ $e := findRE "\\w+$" .Name }}
        {{ if (or ( eq $ext "-") (in $e $ext) )}}
            <a class="w-auto pr2" href={{$f.Permalink }} type=text/plain rel=nofollow download>{{ .Name }}</a>
        {{end}}
    {{end}}

@gj52 these files, do they live below the theme directory?

[gj52]

The shortcode is in the theme directory. Theme extract is here. The listed files are in //etc/

If you need to look in my complete activ repo, send me a PM.

[bep]

@gj52 what I need is something that ... fails, does the "theme extract" fail for you?

[gj52]

Sample does not fail ... mmh I have an idea about - copied some lines

assets/etc is a symbolic link to /etc - I want to dokument my production server all used files have attribute R for everyone, so the user generating the websites can read it all

maybe the links don't work here

HTH

OK, now I actually understand what's happening. Thanks for the detailed explanation.

[bep]

OK, I have tried, but I'm not able to reproduce this error. I assume the issue is related to symlinks, but the devil is in the detail, I'm afraid.

[gj52]

OK,

can depend from the specific OS-runtime

I'm on Linux pi4 5.10.92-v8+ #1514 SMP PREEMPT ... aarch64 GNU/Linux

Ask, if you need more information.

[gj52]

Version 0.93.3 works! Thanks
