Application monitoring is a very important aspect of a project but unfortunately not much attention is paid to develop the effective monitoring while the projects are still movingh to completions. Once project is complete & live lack of proper monitoring costs in terms of downtime when support persons are not aware if application is having some problems or application not working at all.

CoPy In Out
Usage: cpio [OPTION…] [destination-directory]
GNU `cpio’ copies files to and from archives
# Copy files named in name-list to the archive
cpio -o < name-list [> archive]
# Extract files from the archive
cpio -i [< archive]
# Copy files named in name-list to destination-directory
cpio -p destination-directory < name-list
Main operation mode:
Extract files from an archive (run in copy-in
mode) -o, –create Create the archive (run in copy-out mode) -p, –pass-through Run in copy-pass mode
-t, –list Print a table of contents of the input
Operation modifiers valid in any mode:
–block-size=BLOCK-SIZE Set the I/O block size to BLOCK-SIZE * 512
-B Set the I/O block size to 5120 bytes
-c Identical to “-H newc”, use the new (SVR4)
portable format.If you wish the old portable
(ASCII) archive format, use “-H odc” instead.
-C, –io-size=NUMBER Set the I/O block size to the given NUMBER of
–force-local Archive file is local, even if its name contains
-f, –nonmatching Only copy files that do not match any of the given patterns
Use this FILE-NAME instead of standard input or output. Optional USER and HOST specify the user and host names in case of a remote archive
-H, –format=FORMAT Use given archive FORMAT
-M, –message=STRING Print STRING when the end of a volume of the
backup media is reached
-n, –numeric-uid-gid In the verbose table of contents listing, show
numeric UID and GID
–quiet Do not print the number of blocks copied
–rsh-command=COMMAND Use remote COMMAND instead of rsh
-v, –verbose Verbosely list the files processed
-V, –dot Print a “.” for each file processed
-W, –warning=FLAG Control warning display. Currently FLAG is one of
‘none’, ‘truncate’, ‘all’. Multiple options
Operation modifiers valid only in copy-in mode:
-b, –swap Swap both halfwords of words and bytes of
halfwords in the data. Equivalent to -sS
-r, –rename Interactively rename files
-s, –swap–bytes Swap the bytes of each halfword in the files
-S, –swap-halfwords Swap the halfwords of each word (4 bytes) in the
–to-stdout Extract files to standard output
-E, –pattern-file=FILE Read additional patterns specifying filenames to
extract or list from FILE
–only-verify-crc When reading a CRC format archive, only verify the
checksum of each file in the archive, don’t
actually extract the files
Operation modifiers valid only in copy-out mode:
-A, –append Append to an existing archive.
-O [[USER@]HOST:]FILE-NAME Archive filename to use instead of standard output. Optional USER and HOST specify the user and host names in case of a remote archive

-l, –link Link files instead of copying them, when
Operation modifiers valid in copy-in and copy-out modes:
–absolute-filenames Do not strip file system prefix components from
the file names
–no-absolute-filenames Create all files relative to the current
Operation modifiers valid in copy-out and copy-pass modes:
-0, –null A list of filenames is terminated by a null
character instead of a newline
-a, –reset-access-time Reset the access times of files after reading
-I [[USER@]HOST:]FILE-NAME Archive filename to use instead of standard input. Optional USER and HOST specify the user and host
