Question Shell - Read a text file with two words and extract data
hi I made this simple script to extract data and pretty much is a list and would like to extract data of two words separated by commas and I would like to make a new text file that would list these extracted data into a list and each in a new line.

Example that worked for me with text file having 3 fields only:
Code:
#!/bin/bash
IFS=", "
while read f1 f2 f3
do
	echo "$f1"
	echo "$f2"
	echo "$f3"
done < test2.txt > output.txt

and output.txt shows this

Code:
cheek
gingivae
hard
palate
inferior
lip
soft
palate
superior
lip
tongue
uvula

cat test2.txt shows this:
Code:
cheek, gingivae, hard,
palate, inferior, lip,
soft, palate, superior
lip, tongue, uvula

BUT NOW I have a list with more fields and have two words that I need:

new test2.txt shows this:
Code:
right, kidney, right ureter,
urethra, urinary, bladder,
left, adrenal gland, abdominal aorta, inferior vena cava, right renal vein, right renal artery, rectum, uterus

how can I list these 2 word terms into a list with each in its own individual line

THANKS!
