Local Directory Polling Script Example
Please note that this script requires
Beyond FTP Version 2.4.05 or above.
The following script polls a local directory for files to transfer. It does this by waiting at a file presence
conditional for a specified time period. If any file activity occurs in the directory, the
conditional is released, the resulting files are copied, and the script terminates.

# We first create the polling directory, if it is not already there.

:To: C:\BFTPDEMO\Polling\INPUT.BAT
# Next, use the file presence
conditional to wait on files to appear
# in the Polling directory. Wait 5 minutes for something to happen.
# This time could be much longer if you choose, since the script will
# simply be restarted anyway.

# We did not find any files. Simply queue the distribution to start
# again and exit. This statement could actually occur first in the
# script, since we always want the script to run. However, it makes
# canceling the script more difficult. We place it here (and below
# when the script works) to make it easier to cancel things once they
# get started.

:End_If:
# The presence check is satisifed. Copy the files out to the
# destination server. The file is placed on APTServe, where the
# Remote Polling script will pick it up if it is running. Note that
# Archive is set. This means that as the source files are copied,
# they will be moved to c:\BFTPDemo\Polling\Archive.
# This prevents copying the same file twice.

# We delete the archive files when the transfers have completed.
# We could also move them to a different directory, or simply leave

# immediately attempt another transfer.
