it's not "cat" who is breaking lines. This script will fetch content of
"temp1" file to the script, and bash splits fields by any whitespace
charactes, including spaces and tabs, so the "echo" command is calles for
every "word" in a file and echo puts newline at the end of output line by
default.

either change IFS only to contain newline, or forget using $(cat ...) and
use different cycle:
while read line
do
echo "20070622,$line"
done < temp1 > temp2
(or >>temp2 if you want to append to the "temp2" file)
