the age expression
the predicate
Ages are compared in whole units, like find -mtime: a file modified two
and a half days ago is 2 days old, so it matches '=2 days', '>=2 days'
and '<3 days', but not '>2 days'. Days and weeks are calendar days, so
stay correct across daylight saving changes. Ages are measured when each
file is tested.
Matches files by when they were last modified, using an expression of their age: an optional operator, a whole number and an optional unit, such as
'<2 days','>8h'or'>=1 week'.The operators are
<,<=,>,>=and==(or=), which is the default. The units are minutes (m,min,mins,minute,minutes), hours (h,hour,hours), days (d,day,days, the default) and weeks (w,week,weeks), in any case.
