NAME¶
bup-tick - wait for up to one second
SYNOPSIS¶
bup tick
DESCRIPTION¶
bup tick waits until
time(2) returns a different value than it originally
did. Since time() has a granularity of one second, this can cause a delay of
up to one second.
This program is useful for writing tests that need to ensure a file date will be
seen as modified. It is slightly better than
sleep(1) since it sometimes waits
for less than one second.
EXAMPLE¶
-
$ date; bup tick; date
Sat Feb 6 16:59:58 EST 2010
Sat Feb 6 16:59:59 EST 2010
BUP¶
Part of the
bup(1) suite.
