Dan asks: > Interesting. Did 'at' and 'cron' suddenly disappear? Probably not...but they don't appear to be part of POSIX, based on "man cron" on HP-UX :) here's the tail of "man cron": ... STANDARDS CONFORMANCE cron: SVID2, SVID3 BTW, since HP-UX is so good at listing the standards conformance of things, I thought I'd check AIX (on the IBM RS6000) to see what it says about cron. ... It didn't mention any standards. Ok, does it *ever* mention standards? Hmmm...let's try "man ls" on both HP-UX and AIX. HP-UX mentions the POSIX standard, AIX doesn't, so apparently AIX didn't bother to document (via man pages) which commands/utilities meet which standards. However, I did find a reference to HP-UX in an AIX man page..."man ls" yields: ... BUGS On BSD systems, the -s option reports sizes that are half the correct values for files that are NFS-mounted from HP-UX systems. On HP-UX systems, it reports sizes that are twice the correct values for files that are NFS-mounted from BSD systems. This is due to a flaw in HP-UX; it also affects the HP-UX ls program. P.s.: Dan will have to read this on HP3000-L/comp.sys.hp.mpe, since his "From" address is still: ... @bill.pharmcorp.com and that lacks the apparently standard MX records :) which means that my "group reply" will bounce on his address. -- Stan Sieler [log in to unmask] http://www.allegro.com/sieler.html
