`-f` is a file test operator used to see if a file is plain text. In my code, I was just deleting the file if it existed, and probably should have used `-e`. More information on file test operators can be found here. As far as `$\|++`, this stops the buffering of the output. `$\|=1` is cleaner in this case, so I've updated my old node. For more info on `$\|++` and `$\|=1`, here are some interesting, relevant nodes. bassplayer	[reply] [d/l] [select]
