We have multiple mail servers that route mail for internal and external addresses.
Since the file that I need to change is also being used by other applications I would like to just make changes to that file instead of filtering email. By changing the file it allows me to make changes on the fly based on the need.
How would I use ftp to autologin to these 50 systems and overwrite?
I found a snippit of a script that with a little modification may work. added code tags for readability --oombera

__________________________________________________________________________________________________________________________________________________NAME
update - Process pending events and idle callbacks
SYNOPSIS
update ?idletasks?
_________________________________________________________________DESCRIPTION
This command is used to bring the application "up to date" by entering the event loop repeatedly until all pending events (including idle
callbacks) have been processed.
If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are
invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed imme-
diately.
The update idletasks command is useful in scripts where changes have been made to the application's state and you want those changes to
appear on the display immediately, rather than waiting for the script to complete. Most display updates are performed as idle callbacks,
so update idletasks will cause them to run. However, there are some kinds of updates that only happen in response to events, such as those
triggered by window size changes; these updates will not occur in update idletasks.
The update command with no options is useful in scripts where you are performing a long-running computation but you still want the applica-
tion to respond to events such as user interactions; if you occasionally call update then user input will be processed during the next
call to update.
EXAMPLE
Run computations for about a second and then finish:
set x 1000
set done 0
after 1000 set done 1
while {!$done} {
# A very silly example!
set x [expr {log($x) ** 2.8}]
# Test to see if our time-limit has been hit. This would
# also give a chance for serving network sockets and, if
# the Tk package is loaded, updating a user interface.
