Re: [gdal-dev] Proper usage of gdal vsi list

Tue, 28 Oct 2025 11:31:42 -0700 

But, the docs say:
gdal vsi list list files of GDAL Virtual File Systems (compressed, network hosted, etc...): /vsimem, /vsizip, /vsitar, /vsicurl, .... 


...so this implies http dir listings via /vsicurl. I may be interpreting 
that incorrectly, though.

I'd be quite surprised if GDAL's vsicurl was able to understand a directory 
index.

Take https://cscie12.dce.harvard.edu/apache/autoindex/, for example, it's clear 
that's a directory with 7 files, but it also has a bunch of column sorting 
links you'd want to ignore.

To be fair, there aren't that many directory index formats, but I'm not sure 
that parsing them is a job for GDAL.

Using list with /vsicurl only returns results if I specify a file. No
results when specifying a directory. /vsis3 works as expected. Am I
doing this correctly?

Works:
gdal vsi list -lR
"/vsicurl/https://cdn.star.nesdis.noaa.gov/GOES18/ABI/MESO/M1/GEOCOLOR/2025292000425_GOES18-ABI-MESO-GEOCOLOR-39N-119W-1000x1000.jpg";

No workee:
gdal vsi list -lR
"/vsicurl/https://cdn.star.nesdis.noaa.gov/GOES18/ABI/MESO/M1/GEOCOLOR/";

/vsicurl_streaming only returns directory name:
gdal vsi list -lR
"/vsicurl_streaming/https://cdn.star.nesdis.noaa.gov/GOES18/ABI/MESO/M1/GEOCOLOR/";

--depth has no effect.

Debian 12/GDAL 3.12.0beta1

Thanks!
