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)
