Имя (Name)
find-filter - fine-grained file selection based on time
attributes
Синопсис (Synopsis)
$PCP_BINADM_DIR/find-filter [-v?] predicate
Описание (Description)
find-filter is a filter for a list of file names read on standard
input, and if the files match the predicate their names are
written on standard output.
The supported predicate forms are based on the file's creation
time or modification time, and take the form ctime or mtime
followed by a time specification. A time specification takes the
form of a + or - followed by days (a non-negative integer),
optionally followed by a colon (:) and hours (an integer in the
range 0 to 23), optionally followed by another colon (:) and
minutes (an integer in the range 0 to 59).
The semantics of the time specification are that a file matches
the predicate if the chosen time attribute for the file is less
than (+) the current time minus the time specification, else more
than or equal to (-) the current time minus the time
specification. Alternatively, + means before the current time
minus the time specification, and - means at or after the current
time minus the time specification.
find-filter is intended to be used to provide finer-grain and
platform independent selection compared to the -mtime or -ctime
options of find(1). find-filter is expected to be used as a
post-filter for the output from find(1), and this is how it is
used in the pmlogger_daily(1) scripts to select files to be
compressed or culled.
Примеры (Examples)
The following predicate examples illustrate some typical uses.
mtime +3 Matches files modified more than 3 days ago.
ctime -0:2 Matches files created in the last 2 hours.
ctime +0:0:15
Matches files created more than 15 minutes ago.
Диагностика (Diagnostic)
There are none, unless the -v option is used, in which case some
diagnostics are written to standard error.
Exit status is always zero, unless there are errors found when
parsing the command line arguments.
