Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Hi,
I just straced a running sed(1) instance (4.8), and was amazed to see it read its input character by character.
I then remembered that I called it with '-u' because its output was being read by a program that needed it ASAP.
I can't see any benefit to reading stdin by the character, but am prepared to believe a use-case exists. However, I submit that not all use-cases that require unbuffered (or line-buffered) output also automatically need inefficient reading of the input.
Maybe add a new switch for the input part?
Thanks and best regards,
AndrĂ¡s
