Azure File Storage: Move a large quantity of files from one folder to another (on the same fileshare)

azure_move_files.sh

#!/bin/zsh
# Works in zsh-shell on Mac.
# Requires azcopy (https://formulae.brew.sh/formula/azcopy) and az (https://formulae.brew.sh/formula/azure-cli#default)
# As there is no move we copy and rm the files. (The copy is blocking so the remove will not be executed on failure)

export INCLUDEPATTERN=* #can be also sth like *_202010*;*_202011* to filter files (by name) for October/November
