In most cases, the check for a TOP_DIR file finds nothing (which is perfectly fine), resulting in a confusing error message "cat: ../TOP_DIR: No such file or directory" at the top of the log files. This patch removes the error message by redirecting the output for the command to /dev/null. Change-Id: Ifd771621b584c429c211a4c6aaab7d92f981cb72
