Replace should be able to do this, with an expression like this: "[\n\r]+$"

I'm pretty sure you can't match on anchors like that in regex. You'd need to match against the actual characters, like

rex field=Field mode=sed "s/[\r\n]//g"

even sed command is not working ...

rex field=Field mode=sed "s/^$//"

Works well over here. Make sure there aren't any spaces or other characters after the newlines, else the expression will not match.

As a test, consider removing the dollar sign - that should remove every newline from your field, even non-trailing ones.

i have used replace function like this ..

eval Field = replace(Field,"[\n\r]+$","") .. but this didnt work ..

Once should be enough, there's no point in removing trailing newlines again after the first eval.

...or rex mode=sed. I think replace only replaces once.
