Control the file size from the file sink output

Dear GRC’ers

I am just starting to play with GRC. One thing I am playing with is the
file sink. It appears there is no way to control the file size from its
output. This can be dangerous but the continuous sampling at high rate
can
quickly fill up the disk and cause possible disasters.
I am surprised to find that there is no hook in the file sink block for
file/sample size limitation. I would like to see what the community
suggests for dealing with this problem. Another way might be to turn on
the
running of the project code for a certain number of seconds and shuts
off.
Maybe there is a block that can do that. I have not been able to find
one
yet.

Any suggestions are welcome. Thanks,

LD Zhang

Use the head block. It will let the specified number of samples through
and
then stop.
