bin/sleep : sleep.1
Log message:
sleep.1: miscellaneous rewrites, cleanup
Description
- "for a minimum of" is better said "for at least".
- The seconds argument can be zero, so say "non-negative".
- Specify that the number (the whole thing) is decimal to exclude
e.g. hex numbers. It then follows that the optional fraction
must also be decimal.
- No need to inspire the reader to use sleep(1) in any particular way.
It is probably sufficient to demonstrate these patterns in the Examples
section later.
Asynchronous Events
- Note that SIGALRM wakes sleep(1) up "early".
Examples
- Simplify the first example. Parenthetically pointing the reader to
at(1) muddies what is otherwise a trivial example. We can still point
the reader to at(1) in the See Also section later.
- Shorten the interval in the first example. A half hour is not
interactive.
- Get rid of the entire csh(1) example. It's extremely complex and
the bulk of the text is spent explaining things that aren't about
sleep(1) at all.
- Tweak the third example to show the reader that you can sleep
for a fraction of a second, as mentioned in the Description.
Standards
- Prefer active voice.
"The handling of fractional arguments" is better said
"Support for fractional seconds".
Shorten "is provided as" to "is".
History
- Not merely "appeared": "first appeared".
- Note that sleep(1) was reimplemented for 4.4BSD.
