way to force vim to do a read (already in 'autoread')

I have a vim client up and looking at "/tmp/out" and have it said to
autoread the file
as it is the output log of a 'make'.

Sometimes, however, vim won't update and I have to do a ":e<CR>" in the
command line to get vim to update and show me the new error file.

I was creating a script to auto compile files as I saved them -- and that
seems to work.

But vim either takes it's time updating Or misses a file update
notification --
either way, have to do a manual 'e' in the vim window.

Is there a signal I can send to vim to do the same? That way my script,
besides noticing the changes could recompile AND tell vim to
refresh its view of the file.


Thanks!

Linda
