FIND-FILTER(1)           General Commands Manual          FIND-FILTER(1)

NAME

       find-filter - fine-grained file selection based on time
       attributes

SYNOPSIS

       $PCP_BINADM_DIR/find-filter [-v?]  predicate

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.

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.

DIAGNOSTICS

       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.
