Re^4: Buffering issue with \r (backslash r)?

I forgot that <> reads lines (or more accurately, readline or glob, as you pointed out). Rather, I thought it would just read the input as it came. And since I set autoflush for STDOUT, I expected to get it in real time.

Thanks again!

Only `sysread` returns characters as it receives them. `read` returns when the specified number of characters have been read, and `readline` returns when an end of line marker is found. (Reaching the end of file or encountering an error will have them return before that, of course.) I forgot that `<>` reads lines (or more accurately, readline or glob, as you pointed out). `glob` doesn't read files. I pointed out that `<>` can be a shortcut for `glob`, not that `glob` reads lines.	[reply] [d/l] [select]
