#------------------------------------------------------------------------------
# THIS IS A TEST SCRIPT - it substitutes for pull.sh which uses Aspera
# If you don't have an Aspera license, then you can test with this script
# to understand the process.
# IT IS NOT INTENDED FOR PRODUCTION USE!!!!
# -----------------------------------------------------------------------------
# Read filename to get list of files to copy from commit to edge.
# Do the copy using scp (instead of Aspera ascp)
#
# configurable pull.trigger.dir should be set to a temp folder like /p4/1/tmp
#
# Startup commands look like:
# startup.2=pull -i 1 -u --trigger --batch=1000
#
# The trigger entry for the pull commands looks like this:
#
#   pull_archive pull-archive pull "/p4/common/bin/triggers/pull_test.sh %archiveList%"
#
# Assumes that scp is configured and that the standard OS user (e.g. perforce) can ssh
# without passwords between machines.
#
# Standard SDP environment is assumed, e.g P4USER, P4PORT, OSUSER, P4BIN, etc.
# are set, PATH is appropriate, and a super user is logged in with a non-expiring
# ticket.
