set is a shell script command not an HTTPD command.

Yes, the person asking the question knows that. They are using their shell's set command to display all the variables known to the shell session, including environment variables. They were expecting to find an environment variable that contained the data from the HTTP POST request. They know that it isn't a HTTP(D) command. They are asking how to read the HTTP POST data stream from a shell script as opposed to a more typical language like Python or C++.

My advice to the OP is don't use shell scripts (that is, a program written in sh/bash/ksh/zsh or similar languages that adhere to the POSIX 1003 shell standard). That can only lead to much wasted time, bugs, and security holes. Yes, it is technically possible to handle a HTTP POST request using such a shell. But you shouldn't do it.
