Re: (WIN) Autoflush, Perl, Sleep and Powershell

OK, this seems to be a problem with some powershell buffering.

If I print with a newline at the end the output shows directly.

PS D:\tmp> perl -E'$|=1;print qq($]\n);sleep 10' > tmp.log
Terminating on signal SIGINT(2)
PS D:\tmp> cat .\tmp.log
5.032001
PS D:\tmp> perl -E'$|=1;print qq($]);sleep 10' > tmp.log
Terminating on signal SIGINT(2)
PS D:\tmp> cat .\tmp.log
PS D:\tmp>

weird ...

Newline characters (and what happens when you don't have them) are a known headache with PowerShell. If your string always ends with a newline it will be written timely.	[reply]
