Help me see the error of the Service Startup Script

Let me take a look at the error of the Service Startup Script-Linux general technology-Linux programming and kernel information. The following is a detailed description. Run the executable program under/usr/local/bin. d/ypxfrd, slightly changed it, and wrote the following script to run the script (named teststart). An error is reported in red hat 9.0, indicating that the file or directory/etc/rc does not exist. d/init. d/functions! I checked the file in this directory and run ypxfrd using shell. It can be executed normally. but I just modified a few places. the following is my rewritten script. For the first time I wrote this script, there must be other errors. please advise
