Hi !
someone could say me if it's possible to redirect stdout of a program running
in background to a file.
I use writeln() to debug, I would like to redirect results of writeln() into
file. I tried :
program >> /tmp/log 2>&1
program >> /tmp/log
program &> /tmp/log
...never success.

so maybe it's not possible with writeln or I'm missing something.

Thanks !

That should work I usually just use > but no reason append shouldn't work. In fact that method of redirection is purely on your shell to handle.

Ok I found it, I have to put stdout.writeln not writeln. But don't know why we have to force like this. More strange, I only changed the first writeln to stdout.writeln and all next writeln will print in file too !!! If someone know why, I would like to understand.

Thanks.
