NAME

       pmlogmv - move (rename) Performance Co-Pilot archive files

SYNOPSIS

       pmlogmv [-fNV?]  oldname newname

DESCRIPTION

       A Performance Co-Pilot (PCP) archive consists of multiple files as created by pmlogger(1).
       pmlogmv allows all the files of a single PCP archive to be moved or renamed as a group  in
       a single operation.

       The oldname argument identifies the target archive, and may be either the basename that is
       common to all files in that archive or one of the  archive's  files.   The  new  archive's
       basename is newname.

       Because  PCP  archives  are important records of system activity, special care is taken to
       ensure the integrity of an archive's files.  For recoverable problems  encountered  during
       the  execution of pmlogmv, all the files associated with oldname will be preserved, and no
       new files with the newname prefix  will  be  created.   ``Recoverable  problems''  include
       signals  that  can  be  caught  (such as SIGHUP, SIGINT, SIGQUIT and SIGTERM), permissions
       issues, new files already existing, file system full events, etc.

       The implementation of pmlogmv uses hard links in  the  file  system  and  so  follows  the
       semantic  restrictions  of  ln(2)  which for most systems means the directories containing
       both the oldname and the newname PCP archive files need to be  writeable  and  within  the
       same file system.

OPTIONS

       The available command line options are:

       -f, --force
            Normally pmlogmv takes a conservative view in respect of newname and will not proceed
            if newname contains any characters that are likely to  cause  a  problem  for  sh(1).
            This  includes  ``glob''  characters  like  ``?'', ``*'' and ``['', shell syntax meta
            characters like ``('', ``|'', ``;'' and ``&'', shell I/O redirection characters  like
            ``<'' and ``>'', the dollar sign, a space, etc.

            The  -f  flag  forces  pmlogmv  to  proceed,  even  if  newname contains any of these
            ``unsafe'' characters.

       -N, --showme
            Perform a dry-run, checking and reporting what changes would be made  without  making
            any changes.

       -V, --verbose
            Enable verbose mode.

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

DIAGNOSTICS

       All  error  and warning messages are intended to be easily understood and errors produce a
       non-zero exit status.
