Re: BSD sleep
I'm just saying that there's pretty space for discussion. If someone raised this now, why not discuss it now. > If you sleep one hour, do you sleep one hour from now or one hour from the system clock which may change in the next hour? If it's the system clock, you may sleep for ten minutes or ten hours. If you need to sleep for 3600 seconds, that's simple and understandable. How about rephrase it: > If you sleep 3600 seconds, do you sleep 3600 seconds from now or 3600 seconds from the system clock which may change in the next hour? If it's the system clock, you may sleep for ten minutes or ten hours. How "way of specifying period" changing the fact that "internal minimal unit of sleep" is not clearly specified in manpage? Also, there no info on how DST/ ntp time changes affects of running sleeps. I don't see right now how new flag (which currently if specified makes `sleep` exit with help), could break something, but I see that this is could be useful in some cases. This also raise question what sleep should do if something specified incorrectly, like sleep 2h30m30m , or 1h1h or else. And also if any changes would be accepted, this should be specified in manpage (that one about `m` as month). About non-portable feature with non-integers, it was just side observation. -- Regards, Alexander Yerenkow ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Re: BSD sleep
>what is stopping from interpreting 1h in similar manner to 3600? i.e. from now No, this is user-friendly, and thus can't be done :) But if think a second, sleep is used rarely by average users, mostly by programmers and other scripts, and they should know better what they are doing. Seriously, that explanation about different hours is not enough to prevent at least useful option. like sleep -f 1h (-f means force convert, without it you can see good explanation why sleep for 1 hour will be not sleep for 1 hour, and etc, and not get sleep at all.). Exact units in which sleeps happens (seconds, ticks, minutes, years) can be described in manual page, even without accepting m,h - that info would be useful for one. P.S. There is already non-portable feature in sleep - non-integer, and I'm sure that no one thought about some financists from various countries, who used to specify long numbers with separator, e.g. 3.600, and this means for them one hour and not 3 point 6 seconds. -- Regards, Alexander Yerenkow ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

It was a statement, and luckily I was partially wrong, as Vladislav did
made what he wanted to.
However, last time I checked there were no such easy ways to decrease
zpools or increase/decrease UFS partitions.
Or grow mirrored ZFS as easily as single zpool. Or (killer one) remove
added by mistake vdev from zpool ;)
Of course I'm not talking about real hw, rather virtual one.
If you happen to point me somewhere to have such task solved I'd be much
appreciated.

Re: Tell me how to increase the virtual disk with ZFS?
There's no mature (or flexible, or "can do what I want" ) way to
increase/decrease disk sizes in FreeBSD for now {ZFS,UFS}.
Best and quickest way - to have twice spare space, copy data, create new
sufficient disk and copy back.
