-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Bert,
thank you for your suggestion. The way to redirect only from local.sh is working. I thought this wouldn't work, because in my original script remote.sh I also redirect to another temporary output-file. In this case I was wrong. Thank you very much! best regards, Verena Bert Barbe wrote: | With local and locally I mean ofcourse on the host that is running local.sh | e.g;. change local.sh to do | ssh $HOST $REMOTE_SKRIPT >>$OUTPUT | and remove the redirection to $OUTPUT in remote.sh | | Bert | | Bert Barbe wrote: |> Interesting would be to see how the file looks like on the other hosts ;) |> Maybe the file is being extended on the remote host first but the |> write() isn't synced before the local host writes again. |> Why not redirect the output off ssh locally so that all writes are |> local ?
