     @yes Or like this: http://cvsweb.openbsd.org/src/usr.bin/yes/yes.c?rev=1.9&content-type=text/x-cvsweb-markup

     Also best done on GNU where of course they managed to write a needlessly complex version of yes(1) (which is already a useless util).

     this is yes

     while true ; do echo $@ ; done

     @alcinnz It's just the usual.
     
     Reading Unix or Plan9 code is quite refreshing in it's obvious simplicity, even with the old or weird dialects of C.
     
     Reading GNU code often feels like reading some a slightly cleaned up IOCCC contestant software.

     @alcinnz Yeah, because yes(1) is just for repeating a line over and over as an answer to a program, which I can entirely see misbehaving with large writes being sent to it.

     If you need to write a bunch of stuff in a block device or similar just cp /dev/zero /dev/dest (yup, dd is also useless in 99% of cases)
     Specially as their buffer is 8192 bytes rather than 4096.

     And even with that, just filling a long buffer and calling write(2) on it shouldn’t have ended up being that complex.

     @lanodan There's always a kernel between yes & whatever program it's piped to, which should prevent large writes being a problem. And makes minimizing writes ideal.

     And looking it yes(1)'s code now, there really isn't any additional complexity than that. And parsing a minimal set of commandline flags everyone else does.

     Does seem a little silly to spend time optimizing yes(1) like this, but I don't find it worth griping about.

     @lanodan You object to them microoptimizing `yes` by filling an entire buffer with "y\n" (or whatever) before repeatedly outputting it?

     @babble_endanger @alcinnz @lanodan @GNUxeava The WP article suggest that they might have avoided the obvious solution in order to make it 100% unambiguous they weren't copying Unix.

     @GNUxeava @alcinnz @lanodan Someone would have complained if they hadn't. Maybe the optimized one should be a separate program called `very-yes`?

     @lanodan @alcinnz @GNUxeava @babble_endanger Sure. But it's not like they're going to revert the code when it's there, and lose the position as the fastest `yes` implementation in the galaxy. 😁

     Except this stance is very old.
     
     BSD freed a lot of Unix code in ~1995.
     OpenSolaris freed basically all the rest in 2008~2010
     
     It is now 2022.

     @clacke @lanodan @GNUxeava @babble_endanger The other thing you have to remember is that in the late 1980's early 1990's when GNU took off, sysadmins loved the consistancy, reliability, performance, & features introduced by GNU. You got a UNIX machine: You installed GNU on it.

     This was so common that noone saw any reason to explicitly state the "GNU" in GNU+Linux! RMS complaining is him being a victim of his own success.

     @alcinnz @clacke @GNUxeava @babble_endanger Yeah, it's also why I would say GNU×Oracle Solaris to anyone sending me the GNU+Linux thing.
