Re: Sleep Not Sleeping when using without "\n"

STDOUT is buffered. "\n" forces the buffer to empty, and so does auto-flushing. Turn auto-flushing with $|=1, and the "\n" won't be necessary for the print to work immediately.

From the Suffering from Buffering article, link in comment below, we get the line: "The blocks on your disk are probably about 8K bytes." Using that, and your original, non '\n', case, plus the sleep of 1 second, we get: `8K = 8 * 1024 = 8192 bytes 'test' = 4 bytes 8192/4 = 2048 = # of times output will need to happen before you se +e anything due to buffering. 2048 * 1 second sleeps between each output = 2048 seconds 2048 / 60 seconds per minute = 34.1333 minutes to wait.` [download] -Scott	[reply] [d/l]
