NAME

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

SYNOPSIS

       pmlogmv [-cfNV?]  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 tries to use 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 within the same file system.  When this  is  not  possible,  pmlogmv
       falls back to using cp(1) to copy oldname to newname.

OPTIONS

       The available command line options are:

       -c, --checksum
            Paranoid  checking  mode  when cp(1) is needed and each file's checksum is computed for the original
            file and the copied file, and the checksums must match before the  copy  is  considered  acceptable.
            The  checksum command is chosen by trying the following in turn until one is found to be executable:
            md5sum(1), sha256sum(1), sha1sum(1) and sum(1).  If no  executable  checksum  command  is  found,  a
            warning is issued and the checksum check is skipped.

       -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.
