and i need sum all the numbers.

Usually I use awk-

awk '{s=s+$1}END{print s}' yourfile

This will sum the first field in "yourfile" and print the result.

Hope this helps.

For a very simplistic script, you can substitue "000" for "k" and "000000" for "m" to scale the numbers-

awk '{sub("k","000");sub("m","000000");s=s+$1}END{printf "%15d\n",s}' yourfile

Hope this helps more...

How's this??

echo 0 `cat textfile | sed -e "s/ //g" -e "s/RSS/0/" -e "s/M/000K/" -e "s/K/000/" -e "s/^/+ /"` | bc
