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

I'm using Ant to deploy various components to different servers and I'm
looking for a way to enumerate files/folders on a remote server and then
selectively delete them. So I don't know everything that will be there
but I know the folders I want to leave undeleted. I'm looking for some
kind of foreach loop or something that will work for me.
I'm using Ant 1.7.0 on AIX 5.3 servers.
I'm looking for help on how to enumerate each line in a file. And then I
guess the best method would be to modify that file to remove the folders I
don't want to delete and use that to sshexec once and delete files/folders
rather than doing an sshexec for each line item. ie. sshexec across once
and delete all in a loop versus loop and sshexec for each item.
I can echo what's in that remote location using this:
<sshexec host="${target.server}" username="${target.user}"
password="${targe
t.password}" failonerror="true" trust="true"
output="${deploy.temp.dir}/remote
list.txt" append="false" command=". $HOME/.profile; cd ${dc.fs}; ls" />
Now I'm trying to read remotelist.txt line by line and delete everything
excluding certain folders. I'm having trouble splitting the lines.
Here's a couple of things I've tried.
1.
<foreach list="${deploy.temp.dir}/remotelist.txt" delimiter=" "
param="itemfound" target="rmitem" />
In target, rmitem, for now I'm just trying to echo the lines in
remotelist.txt but eventually I'll need to do an sshexec with an rm -rf
${line}.
2.
<foreach item="Line" in="${deploy.temp.dir}/remotelist.txt"
property="item
found">
<echo message="Read line ${itemfound}" />
</foreach>
Error: foreach doesn't support the "item" attribute
3.
<loadfile property="allfiles"
file="${deploy.temp.dir}/remotelist.txt"/>
<for list="${allfiles}" param="itemfound">
<echo message="Read line ${itemfound}" />
</for>
Error: loadfile doesn't support the "file" attribute
4.
<loadfile srcFile="${deploy.temp.dir}/remotelist.txt" property="line">
<echo message="Read line ${line}" />
</loadfile>
Error: loadfile doesn't support the nested "echo" element.
5.
<loadfile srcFile="${deploy.temp.dir}/remotelist.txt"
property="line"/>
<echo message="Read line ${line}" />
Error: this echos all of items found in ls as 1 item, ${line}
6.
<loadfile property="src" srcFile="${deploy.temp.dir}/remotelist.txt"/>
<for param="line" list="${src}" delimiter="${line.separator}">
<sequential>
<echo message="Read line ${line}" />
</sequential>
</for>
Error: echos 1 line multiple times - [echo] Read line: ${line}
