Does the data always appear in this format (i.e. the FG=<someval>) prior to the closing brace?

If so

$ echo "message={TP=2012:09:23:00:00:00:GMT,SD=2012:09:23:00:00:00:GMT,SP=2,FT=CCGT,FG=3605}" | sed 's/^.*,\(FG=[^}]*\)}.*$/\1/'

will do the trick ...

If I have a file that contains multiple lines of the same format, is there a way to extract all the FG=???? at the same time and save to a new file? thanks

If position is reliable
$ FG=$(echo 'message={TP=2012:09:23:00:00:00:GMT,SD=2012:09:23:00:00:00:GMT,SP=2,FT=CCGT,FG=3605}' | awk -F\, '{print $NF}'|  sed 's/\}//g')

$ echo $FG

Yup - many ways to skin the cat.

As for the question about multiple lines - yes

bash-3.2$  sed 's/^.*,\(FG=[^}]*\)}.*$/\1/' input_file > output_file

Even works over multiple files:

bash-3.2$ for i in 1 2 3 4; do
> echo "message={TP=2012:09:23:00:00:00:GMT,SD=2012:09:23:00:00:00:GMT,SP=2,FT=CCGT,FG=360${i}}" > file_${i}
> done
bash-3.2$ sed 's/^.*,\(FG=[^}]*\)}.*$/\1/' file_{1,2,3,4} > foo.txt
bash-3.2$ cat foo.txt
