smart grep for counting numbers

hi ,

I have this kind of text :

repeat (200) @(posedge `TXQ_BOARD.clk); // ` For

repeat (10) @(posedge `TXQ_BOARD.clk); // ` For

repeat (100) @(posedge `TXQ_BOARD.clk); // ` For

repeat (100) @(posedge `TXQ_BOARD.clk); // ` For

I have got meny lines like that , and I want to
summarize the numbers : 200 + 10 + 100 +100
within a script that get the text.file as an input
and outputs the sum .

Hi  Talmash,

    Here's a little script for you to do the job:

#===================================================
#!/usr/bin/sh
INFILE=your-input-file
num=0
sum=0
for num in `cat ${INFILE} | awk '{print $2}' | tr -d "()"`
do
     sum=`expr ${sum} + $num`
done

echo " The Sum is ${sum} \n"

#====================================================

    Cheers!

Regards

Hi Talmash

   I forgot to tell you that you need to grep the lines with numbers first,
then, use the script above to do your job.

   eg
                                                                                                         
                        #===================================================   #!/usr/bin/sh
 INFILE=your-input-file
 num=0
 sum=0
 for num in `cat ${INFILE} | awk '{print $2}' | grep "([1-9]" | tr -d "()"`
 do
 sum=`expr ${sum} + $num`
 done

 echo " The Sum is ${sum} \n"

                        #====================================================
