Options -f, -F #182

Open jodavies opened 7 years ago

jodavies commented 7 years ago

Hello,

Is it intended that when running with option -f ("Output goes only to log file."), expressions printed with print are still printed to screen? This doesn't seem to match the description.

Thanks, Josh.

Hi,

As far as I know, it is descibed that you need print +f for that. Or is that only in the print statement description?

print +f combined with the -f option does suppress all output, right.

Of course, one can "suppress" everything with > /dev/null anyway.

The print +f, together with form -l sends whatever is in the print to the log file. I missed the difference between -l and -f. Sorry about that. I never use -f. Hence if it does not work well, that could be a bug that nobody ever reported. Let us keep that as an issue for the next time I have some time to go after bugs like that. (I always use print +f and then form -l).
