# 08/03/11 - Siggi - adjustments for ibmkisti: this machine allows
#                    outgoing ssh/scp connections only from the
#                    interactive nodes (gaiad). All ssh/scp traffic is
#                    done via this interactive node.
# 04/01/02 - Siggi - first version finished
# 29/11/01 - Siggi - script development started

# batch_scp - script for automatic file/directory transfers using scp
#
# batch_scp has up to 5 arguments (first 4 are mandatory):
#               $1 = IP-addres of remote (target) machine
#               $2 = file to be transferred
#               $3 = directory of remote machine, where file should be copied to
#               $4 = filename that file should be given on remote machine
#               $5 = file extension (optional argument)
#
# ATTENTION: problems might occur if directories on remote machine include very
#            old files for which "ls -al" does give "year" as modification
#            time instead of "hh:mm". In such a case, batch_scp cannot check the
#            filename and may not find the file (e.g. if option -g is used).
