Hi Daptal
Many Thanks for the reply
The option you suggested works.
However I am not sure if it will ipmact the performance, since the (exists) test will be carried for each file individually
This is like -exec
Do we have any option like xargs which will execute only once for this?
Initially I thought of 'diff' for comparing the files in directories but it compare contents of the files as well which is not feasible in my case since I have binary files of quite big size
These are Oracle archivelog files, each 150-200 Mb and large number of quantity
Also I tried following which too is slow
ls -ltr dir1>dir1FileList.txt
ls -ltr dir2>dir2FileList.txt
diff dir1FileList.txt dir2FileList.txt|awk '{print $9}'>reqdFiles.txt
Thanks and Regards,
Chetana

I need to copy about 13 Tb of data from one directory and subdirectories to the other (another mount point). If I run this as a cron, say between 10 pm and 7 am, not all of the files will be copied over. Is there a way of 'resuming' the copy the following evenings until all files are copied over?

install
INSTALL(1) BSD General Commands Manual INSTALL(1)
NAME
install -- install binaries
SYNOPSIS
install [-bCcMpSsv] [-B suffix] [-f flags] [-g group] [-m mode] [-o owner] file1 file2
install [-bCcMpSsv] [-B suffix] [-f flags] [-g group] [-m mode] [-o owner] file1 ... fileN directory
install -d [-v] [-g group] [-m mode] [-o owner] directory ...
DESCRIPTION
The file(s) are copied to the target file or directory. If the destination is a directory, then the file is copied into directory with its
original filename. If the target file already exists, it is either renamed to file.old if the -b option is given or overwritten if permis-
sions allow. An alternate backup suffix may be specified via the -B option's argument.
The options are as follows:
-B suffix
Use suffix as the backup suffix if -b is given.
-b Back up any existing files before overwriting them by renaming them to file.old. See -B for specifying a different backup suffix.
-C Copy the file. If the target file already exists and the files are the same, then don't change the modification time of the target.
-c Copy the file. This is actually the default. The -c option is only included for backwards compatibility.
-d Create directories. Missing parent directories are created as required.
-f Specify the target's file flags; see chflags(1) for a list of possible flags and their meanings.
-g Specify a group. A numeric GID is allowed.
-M Disable all use of mmap(2).
-m Specify an alternate mode. The default mode is set to rwxr-xr-x (0755). The specified mode may be either an octal or symbolic
value; see chmod(1) for a description of possible mode values.
-o Specify an owner. A numeric UID is allowed.
-p Preserve the modification time. Copy the file, as if the -C (compare and copy) option is specified, except if the target file
doesn't already exist or is different, then preserve the modification time of the file.
-S Safe copy. Normally, install unlinks an existing target before installing the new file. With the -S flag a temporary file is used
and then renamed to be the target. The reason this is safer is that if the copy or rename fails, the existing target is left
untouched.
-s install exec's the command strip(1) to strip binaries so that install can be portable over a large number of systems and binary
types.
-v Causes install to show when -C actually installs something.
By default, install preserves all file flags, with the exception of the ``nodump'' flag.
The install utility attempts to prevent moving a file onto itself.
Installing /dev/null creates an empty file.
DIAGNOSTICS
The install utility exits 0 on success, and 1 otherwise.
FILES
INS@XXXX If either -S option is specified, or the -C or -p option is used in conjuction with the -s option, temporary files named INS@XXXX,
where XXXX is decided by mkstemp(3), are created in the target directory.
COMPATIBILITY
Historically install moved files by default. The default was changed to copy in FreeBSD 4.4.
SEE ALSO
chflags(1), chgrp(1), chmod(1), cp(1), mv(1), strip(1), mmap(2), chown(8)
HISTORY
The install utility appeared in 4.2BSD.
BUGS
Temporary files may be left in the target directory if install exits abnormally.
File flags cannot be set by fchflags(2) over a NFS file system. Other file systems do not have a concept of flags. install will only warn
when flags could not be set on a file system that does not support them.
install with -v falsely says a file is copied when -C snaps hard links.
