FWIW - it seems to me you may not know about a shell facility called a here document.
It lets you write code that dynamically enters data for another program like mysql, and behaves as is if it was you directly typing into the program. What you are doing is temporarily replacing stdin with a shell script or an awk script, or a really complex set of statements, etc. The kind of thing data entry staff employees did 50 years ago.
Syntax: we are going to feed the program yesterday's date and last Friday's date, as a very simple example (uses linux/GNU date in the example)
the <<EOF tells the shell to start feeding "keystrokes" to /path/to/program EOF is block name could be anything, Charlie or Baris or !
the EOF marks the end of the code block. This has to be in the LEFTMOST column
Most of what you asked for help with can be handled more easily with a here document.
