10
12 A Performance Co-Pilot (PCP) archive consists of multiple files as cre‐
13 ated by pmlogger(1). pmlogmv allows all the files of a single PCP ar‐
14 chive to be moved or renamed as a group in a single operation.
15
16 The oldname argument identifies the target archive, and may be either
17 the basename that is common to all files in that archive or one of the
18 archive's files. The new archive's basename is newname.
19
20 Because PCP archives are important records of system activity, special
21 care is taken to ensure the integrity of an archive's files. For
22 recoverable problems encountered during the execution of pmlogmv, all
23 the files associated with oldname will be preserved, and no new files
24 with the newname prefix will be created. ``Recoverable problems''
25 include signals that can be caught (such as SIGHUP, SIGINT, SIGQUIT and
26 SIGTERM), permissions issues, new files already existing, file system
27 full events, etc.
28
29 The implementation of pmlogmv uses hard links in the file system and so
30 follows the semantic restrictions of ln(2) which for most systems means
31 the directories containing both the oldname and the newname PCP archive
32 files need to be writeable and within the same file system.
33
35 The available command line options are:
36
37 -N, --showme
38 Perform a dry-run, checking and reporting what changes would be
39 made without making any changes.
40
41 -V, --verbose
42 Enable verbose mode.
43
44 -?, --help
45 Display usage message and exit.
46
48 All error and warning messages are intended to be easily understood and
49 errors produce a non-zero exit status.
