How to copy very large directory trees
I have constant trouble with XCOPY/s for multi-gigabyte transfers.
I need a utility like XCOPY/S that remembers where it left off if I reboot. Is there such a utility? How about a free utility (free as in free beer)?

How about an md5sum sanity check too?

I posted the above query in another forum. Answers to the above question are welcome here too. My question for this forum is: How feasible is it it write a script in groovy, python, cygwin bash, Activestate perl, powershell, etc... to implement a linux "cp -R" or windows "xcopy/s" program that can continue where it left off after a reboot?

I cannot think of clever way do do this easily -- can you?

I could write it in C++ -- but I'm hoping for something more quick and elegant.


Thanks
Siegfried

nice

NICE(1) 						    BSD General Commands Manual 						   NICE(1)

NAME

     nice -- execute a utility at an altered scheduling priority

SYNOPSIS

     nice [-n increment] utility [argument ...]

DESCRIPTION

     The nice utility runs utility at an altered scheduling priority, by incrementing its ``nice'' value by the specified increment, or a default
     value of 10.  The lower the nice value of a process, the higher its scheduling priority.

     The superuser may specify a negative increment in order to run a utility with a higher scheduling priority.

     Some shells may provide a builtin nice command which is similar or identical to this utility.  Consult the builtin(1) manual page.

ENVIRONMENT

     The PATH environment variable is used to locate the requested utility if the name contains no '/' characters.

EXAMPLES

     Execute utility 'date' at priority 5 assuming the priority of the shell is 0:

	   nice -n 5 date

     Execute utility 'date' at priority -19 assuming the priority of the shell is 0 and you are the super-user:

	   nice -n 16 nice -n -35 date

DIAGNOSTICS

     If utility is invoked, the exit status of nice is the exit status of utility.

     An exit status of 126 indicates utility was found, but could not be executed.  An exit status of 127 indicates utility could not be found.

SEE ALSO

     builtin(1), csh(1), idprio(1), rtprio(1), getpriority(2), setpriority(2), renice(8)

COMPATIBILITY

     The traditional -increment option has been deprecated but is still supported.

STANDARDS

     The nice utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     A nice utility appeared in Version 4 AT&T UNIX.
