The idea behind this is that there is one deployment server that deploys
code to multiple envs with various middleware components (Oracle,
Websphere, Message Broker, Business Objects) stored on multiple lpars. So
I need to drop files, run scripts, deliver middleware components to 3
lpars for any given environment.
We don't really want to install Ant on all systems, just the deployment
server. We are already doing a lot of this type of work this way. I
just need to learn how to read a file by line in Ant and get the output of
that line so I can perform an action on it.
criteria for deleting
I have a set location with set folders that get created and deleted. The
problem is other people could also drop information to that location that
I want to cleanup.
ie. mainfolder
folder1
folder2
folder3
folder4
I want to delete folder3 and 4 at this location but leave folder1 and 2 (I
know the names of the folders so the exclude decision is not an issue).
I also want to delete anything else that someone drops there.
ie. folder5
text.txt
I am archiving the whole thing first so zip'ing mainfolder. Then cleaning
up part of it and recreating part of it, but some of it needs to stay. ie.
leaving an archive directory where the zips are stored. Leaving folder
where part of app installed.

Subject: Re: Selectively delete files/folders on another server
Hello Maureen,
would it be possible to install ant on the target machines and move the
logic to determine folders
to be deleted there ? this might be a way to do this work more simply.
What is the criteria according to which you know which directories/files
to delete or to preserve ?
Regards,
Antoine
