This is untested, but it should be close:
This way you copy the file to $newdir only if it is not already there. Also the presense of the file in the old directory will inhibit the copy. From what you said, this will save copying thousands of files. Now no rm step is needed. The files renamed as they were copied, no separate rename step needed either.
Hi,
I am trying to implement the synchronize feature of java using C. I am using a semaphore for the same. I have a wrapper called "synch" to which I pass the function pointer(any_fn). This pointer points to the function (my_fn) which needs to be synchronized.
However to create the semaphore I... (8 Replies)

Hi everyone!
I need to write a script that will synchronize two servers using FTP. So basically the script will get only the files that exist on the remote server that do not exist on the local server. Is there an option to do this when using mget? If not, is there a way to copy over only the... (2 Replies)

nfanon - netflow anonymisation
SYNOPSIS
nfanon [options]
DESCRIPTION
nfanon is used to anonymise all IP addresses ( src, dst, next hop, router IP etc. ) in the netflow records using the CryptoPAn (Cryptogra-
phy-based Prefix-preserving Anonymization) module. The key -K is used to initialize the Rijndael cipher. The key is either a 32 character
string, or a 64 hex digit string starting with 0x.
See http://www.cc.gatech.edu/computing/Telecomm/cryptopan/ for more information about CryptoPAn.
nfanon has several modes of operation.
o nfanon reads a sequence of input files, specified by -r, -R and -M and anonymises the flows in the given files. The input file arguments
have the same syntax and meaning as nfdump(1).
o nfanon reads a sequence of input files, specified by -r, -R and -M. All anonymised flows are written to a single file specified by -w.
o nfanon works as filter and reads flows from stding and writes the anonymised flows to stdout.
OPTIONS -r inputfile
Read input data from inputfile. Default is read from stdin.
-R expr
Read input from a sequence of files in the same directory. expr may be one of:
/any/dir Read recursively all files in directory dir.
/dir/file Read all files beginning with file.
/dir/file1:file2 Read all files from file1 to file2.
Note: files are read in alphabetical sequence.
-M expr
Read input from multiple directories. expr looks like: /any/path/to/dir1:dir2:dir3 etc. and will be expanded to the directories:
/any/path/to/dir1, /any/path/to/dir2 and /any/path/to/dir3 Any number of colon separated directories may be given. The files to read are
specified by -r or -R and are expected to exist in all the given directories. The options -r and -R must not contain any directory part
when used in conjunction with -M.
-w outputfile
If specified writes anonymised netflow records to outputfile.
-K key
The key is used to initialize the Rijndael cipher. key is either a 32 character string, or a 64 hex digit string starting with 0x.
RETURN VALUE
Returns
0 No error.
255 Initialization failed.
250 Internal error.
NOTES
None.
