Is there a way to redirect the output of pv command to a file?

Question

I need to redirect the output of pv command to a file so i get read it's progress from another process. Or is it any other way i could do that?

Answer 1

The progress info goes to standard error so have you tried a | pv ... -f 2> /tmp/out | b? Otherwise an adaptation of the more complicated example from the man page may be used:

( a | pv ... -f | b ) > /tmp/out 2>&1

Stdio buffering may present a problem.
