NAME         top

       pmlogger_rewrite - helper script to rewrite Performance Co-Pilot

SYNOPSIS         top

       $PCP_BINADM_DIR/pmlogger_rewrite [-dNsVvw?]  [-c config] archive

DESCRIPTION         top

       pmlogger_rewrite is a helper script that is used by
       pmlogger_daily(1) when rewriting Performance Co-Pilot (PCP)
       archives.  Rewriting is usually required to accommodate
       evolutionary changes in metadata so old archives can be updated
       and then merged with current archives.

       pmlogger_rewrite is a wrapper script for pmlogrewrite(1) that
       will potentially rewrite all of the archives matching the archive
       arguments.  Each archive argument may be a PCP archive file name,
       the basename for the files in a PCP archive, or a directory (in
       which case all subordinate PCP archives are found by recursive

       pmlogrewrite is run with the -i option so rewriting is done ``in
       place''.  The -q option is also used, so if no rewriting is
       required then no changes are made to the archive files.

OPTIONS         top

       The following options are passed through to pmlogrewrite: -c (or
       --config), -d (or --desperate), -s (or --scale), -v (or
       --verbose) and -w (or --warnings).  Refer to pmlogrewrite(1) for
       the meaning of these options.

       The remaining options are:

       -N, --showme
            Runs pmlogger_rewrite in a ``show me'' or ``dry run'' mode
            where the tasks that would be performed are reported, but no
            changes are made.  This is typically used for debugging in
            combination with one (verbose) or two (very verbose) -V

       -V, --verbose
            Increase script output verbosity.

       -?, --help
            Display usage message and exit.


       Environment variables with the prefix PCP_ are used to
       parameterize the file and directory names used by PCP.  On each
       installation, the file /etc/pcp.conf contains the local values
       for these variables.  The $PCP_CONF variable may be used to
       specify an alternative configuration file, as described in
