I'm trying to approximate the computer's write speed using dd:
dd if=/dev/urandom of=/dev/null bs=1K count=10000
which gives the following output
10000+0 records in 10000+0 records out 10240000 bytes (10 MB) copied, 0.746313 s, 13.7 MB/s
How can I get the '13.7 MB/s' into a bash variable? I've tried piping the output from dd to progs like awk, sed and grep to no avail.
Ultimately, I'm calling this via
os.system(...) from within a python script. If anyone knows of a more direct way to get a similar result inside python I'd be interested in that also. I'm trying to predict how long a file copy will take, based on the file size.
Any help would be greatly appreciated.
