Description Ralf Hauser 2003-09-30 09:31:39 UTC 
My build.xml creates a (txt or ftl) file containing a record per line.

Now, each ant run re-creates a possibly slightly changed set of records.

When using shell scripts, I can use "uniq" to solve the problem of getting rid
of duplicate lines (although I first have to "sort" which I rather would not).

==> it would be great if the echo task could do that too!
