.SH DESCRIPTION
.B pmlogger_rewrite
is a helper script that is used by
.BR 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.
.PP
.B pmlogger_rewrite
is a wrapper script for
.BR pmlogrewrite (1)
that will potentially rewrite all of the archive logs matching the
.I archive
arguments.
Each
.I 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
descent).
.PP
.B pmlogrewrite (1)
is run with the
.B \-i
option so rewiting is done ``in place'' and the
.B \-q
option so if no rewriting is required then no changes are made to the
archive files.
.PP
Using
.B \-N
option runs
.B 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)
.B \-V
options.
.PP
The following options are passed through to
.BR pmlogrewrite :
.BR \-c ,
.BR \-d ,
.BR \-s ,
.BR \-v
and
.BR \-w .
Refer to
.BR pmlogrewrite (1)
for the meaning of these options.

.SH "PCP ENVIRONMENT"
Environment variables with the prefix
.B PCP_
are used to parameterize the file and directory names
used by PCP.
On each installation, the file
.B /etc/pcp.conf
contains the local values for these variables.
The
.B $PCP_CONF
variable may be used to specify an alternative
configuration file,
as described in
.BR pcp.conf (5).
