Apparently you misunderstood things. To give a simplified example: if I enter echo -n "hello";echo " world" Does the second echo know it's putting part of "hello world" on screen? Of course not. To get back to trn+yEnc: in ydecode article1 ydecode article2 ydecode article3 ydecode article4 "ydecode article2" doesn't know there even was an article1, since that wasn't fed to the ydecode process with the same PID. The only thing ydecode can detect is that it has a 'part=2' yEnc article and the output file already exists. What that output file contains, ydecode doesn't know; it could be the decoded data from article1 or it could be a text file with the line "trn has problems with yEnc decoding" in it... ;) So to handle an existing output file, it can 1) overwrite, 2) write to a new file or 3) "blindly apend" to it. With some nudging, uudeview run from trn can be made to do option 1 and maybe option 2; I don't know how ydecode handles it.
