Hi all!,

---here is my sample script----
echo "Enter the size of the file to be created: "
read size
echo "How many files will be created? "
read quantity
i=1
while [ $i -le $quantity ]
do
dd if=/dev/zero of=file$i bs=1M count=$size 2> /dev/null
echo "File$i created...."
i=`expr $i + 1`
done

the output is
File1 created....
File2 created....

here is the output of dd command:
dd if=/dev/zero of=file1 bs=1M count=1
3+0 records in
3+0 records out
3145728 bytes (3.1 MB) copied, 0.088105 seconds, 35.7 MB/s

How can I get the character "35.7 MB/s" or maybe the whole 3rd line and then I can append this to the output of the script.
like:
File1 created....35.7 MB/s
File2 created....35.7 MB/s

thanks for any help....

Hmm...

Try as follows (may be in your loop):

ok, so we need to create temporary file..
I have here my sample script, its not that good but it works
I search the line that contains the character MB then get the last two words.

( dd if=/dev/zero of=file$i bs=1M count=$size ) 2> tmp.txt
echo "File$i created..`awk '/MB/ {print}' tmp.txt | awk '{print $8" "$9}'`"

my output now is :
File1 created...9.5 MB/s

its not that useful if the files are small because it will print so fast but in large files, its very useful because you can have an idea about the performance of your system.

thanks a lot,
warren
