note bassplayer <code>-f</code> 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 <code>-e</code>. More information on file test operators can be found [perlfunc:_X|here].<br><br> As far as <code>$|++</code>, this stops the buffering of the output. <code>$|=1</code> is cleaner in this case, so I've updated my old node. For more info on <code>$|++</code> and <code>$|=1</code>, here are [id://57592|some] [id://210529|interesting], [id://280025|relevant] [id://344772|nodes].<br><br> <div class="pmsig"><div class="pmsig-149104"> <p> bassplayer </div></div> 383597 383857
