71# 08/03/11 - Siggi - adjustments for ibmkisti: this machine allows
72#                    outgoing ssh/scp connections only from the
73#                    interactive nodes (gaiad). All ssh/scp traffic is
74#                    done via this interactive node.

79# batch_scp - script for automatic file/directory transfers using scp
80#
81# batch_scp has up to 5 arguments (first 4 are mandatory):
82#               $1 = IP-addres of remote (target) machine
83#               $2 = file to be transferred
84#               $3 = directory of remote machine, where file should be copied to
85#               $4 = filename that file should be given on remote machine
86#               $5 = file extension (optional argument)
87#
88# ATTENTION: problems might occur if directories on remote machine include very
89#            old files for which "ls -al" does give "year" as modification
90#            time instead of "hh:mm". In such a case, batch_scp cannot check the
91#            filename and may not find the file (e.g. if option -g is used).
