Add 'gdal vfs list/copy/delete'

[rouault]

• Add 'gdal vfs list', alias 'gdal vfs ls' (replacement for gdal_ls.py sample script)
• Add 'gdal vfs copy', alias 'gdal vfs cp' (replacement for gdal_cp.py sample script)
• Add 'gdal vfs delete', alias 'gdal vfs rm' (replacement for gdal_rm.py sample script)

Would it be too long as vfs list, stands for "virtual file system - list"?

[rouault]

I'm open for vfs instead of fs. The advantage of ls is that this is a standard Unix name (and the -l and -R flags are exactly the ones of ls). That said we have the concept of aliases for command names, so the long name could be list, with ls as alias

done. As well as the addition of "copy" and "delete"

Sorry I didn't see this until just now. I wonder if it should maybe be named gdal vsi {ls|delete|copy} to align it with everything else and to denote that it can and should take VSI links.

[rouault]

that it can and should take VSI links.

it can also accept regular paths. Can people watching this PR vote whether they prefer "vfs" or "vsi" ?

[jratike80]

They have 3 letters both but I do not understand what they really mean, so please select your favourite. +0 for both from me.

[msmitherdc]

i guess vsi

[rouault]

ok let's go for vsi ==> #12142

Finally found what VSI means - naturally "Virtual System Interface" https://lists.osgeo.org/pipermail/gdal-dev/2005-September/006426.html
