basic_listing

Run fls to list your current directory.

demo

$ touch aaa.001.tif aaa.002.tif aaa.003.tif aaa.004.tif aaa.005.tif foo_bar.exr
$ fls
foo_bar.exr
aaa.***.tif@1-5

Run fls -- /path/of/directory/ to list a specific directory.

Exemple with the sample set big at the root level of the repo

$ fls -- samples/big/

Exr Metadata

Inspired by rvls. You can use -l

Run fls -l to list your current directory and display EXR informations.

Run fls -l -- /path/of/directory/ to list a specific directory and display EXR informations.

Recursive

You can use a recursive approch of the directory and sub-folder

You can use -r

Run fls -r -- /path/of/directory/ to list a specific directory and his subfolder

$ fls -r -- .\samples\
