Синопсис (Synopsis)
pmlogmv
[-fNV?
] oldname newname
Описание (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.
Параметры (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.
Диагностика (Diagnostic)
All error and warning messages are intended to be easily
understood and errors produce a non-zero exit status.
