# FILE: move_shownotes

# USAGE: ./move_shownotes original_show new_show
|
|
#
|
|
# DESCRIPTION: After a show has been moved from one slot to another on the
|
|
# HPR server this script ensures that the local versions of
|
|
# processed show notes correspond to the change by moving
|
|
# directories around and correcting file names and some
|
|
# contents.
|
|
#
|
|
# ** Under development **

Usage: ./${SCRIPT} [-h] [-d] [-D] original_show new_show
|
|
|
|
Version: $VERSION
|
|
|
|
When a show has been processed and posted on the server, but needs to be moved
|
|
to another slot (after getting the host's permission) this script assists with
|
|
the processes involved in ensuring the local shownote caches reflect the
|
|
server state.
|
|
|
|
The need to move a show is rare, but often follows when a host has forgotten
|
|
the request to spread their shows out by at least two weeks and has sent them
|
|
in to clots too close in time to one another.
|
|
|
|
Options:
|
|
-h Print this help
|
|
-d Select dry run mode
|
|
-D Turn on debug mode with lots of extra output
|
|
|
|
Arguments:
|
|
original_show
|
|
new_show
|
|
|
|
Both arguments can use either an integer number or a format like 'hpr9999'
|
|
and also compensate for the use of 'HPR' rather than 'hpr'.
|
|
|
|
Examples
|
|
./${SCRIPT} -h
|
|
./${SCRIPT} -d 3742 3756
|
|
./${SCRIPT} -D 3738 3746
|
