 Description

 -----------

 

+Update: 2019-08-14

+

+Have just looked at this after several years of bitrot and made some updates.

+it functions for cli DAV access on your assigned hub, but magic-auth to dav repos on other hubs

+(e.g. the host command) needs to be updated to work with openwebauth.

+

+----

 ZotSH is a command line WebDAV client for Hubzilla.

 It knows how to magic-auth to remote hubs using Zot.
