o (documented) For "cat -u", the "-u" is always in effect; provided for compatibility but otherwise ignored. o (not well documented) stderr tends to be written unbuffered; stdout buffered. o However, if stdout is written to a TTY, it's also unbuffered. o However, if stdout is written to a pipe it's buffered again. But sometimes the pipe is to a simple filter whose output to TTY I'd like to see promptly, not buffered. I'd prefer that the decision were conditioned on special file vs. regular file, rather than TTY vs. non-TTY. In my own code, I can well control these behaviors with setvbuf() and/or fflush(). >Am 01.07.2016 um 14:14 schrieb Kurt Quackenbush: >>> [snip!] >>> Speaking of SMP/E ... I impatiently wish that I could get SMPOUT and SMPRPT buffered less. But I have such a Rube Goldberg of pipes, filters, and SYSOUTs that I can form no rationale for an SR or an RFE. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
