Copying files with increment in destination
Hi..
i have a source and destination directories & want to copy files from source to destination those files are unique to source directory . And those files are common to both the directory copy source to destination with a numeric increment as extension.
If in the destination there are more than 4 source directory of same files then that file won't copy to destination further.
i've done it with time stamp , Need your help for numeric increment and checking number of file condition before copy.
Code:
$ls  aa/
a.gif
a.txt
k.xml
$ls bb/
a.gif                          a.txt                        k.xml
a.gif_2010003181244    a.txt_2010003181244  k.xml_2010003181244

Code:
#!/bin/sh  
s_dir=~/acct/a/aa
d_dir=~/acct/a/bb
ls -1 $s_dir|sort>temp_1
ls -1 $d_dir|sort>temp_2

if [  `comm -23 temp_1 temp_2|wc -l` -gt 0 ];then
for file in `comm -23 temp_1 temp_2`
do 
cp $s_dir/$file $d_dir/$file
done
fi

ls -1 $d_dir|sed 's/\(.*\)\_.*/\1/'|sort|uniq -c | awk '{print $1,$2 }'>temp_3

for val in `awk '{print $1}' temp_3`
do

if [ $val -lt 4 ];then
for file in `awk '{print $2}' temp_3` 
do 
cp $s_dir/$file $d_dir/$file`date +"_%Y%m%d%H%M"`
done 
fi
done
rm temp_1 temp_2

But i need the destination directory should be as
Code:
a.gif       a.txt      k.xml
a.gif_1    a.txt_1   k.xml_1

and for next running of script it should be
Code:
a.gif       a.txt      k.xml
 a.gif_1    a.txt_1   k.xml_1
a.gif_2    a.txt_2   k.xml_2

Thank & Regards

cpmac

CPMAC(1)						    BSD General Commands Manual 						  CPMAC(1)

NAME

     /usr/bin/CpMac -- copy files preserving metadata and forks

SYNOPSIS

     /usr/bin/CpMac [-rp] [-mac] source target
     /usr/bin/CpMac [-rp] [-mac] source ... directory

DESCRIPTION

     In its first form, the /usr/bin/CpMac utility copies the contents of the file named by the source operand to the destination path named by
     the target operand.  This form is assumed when the last operand does not name an already existing directory.

     In its second form, /usr/bin/CpMac copies each file named by a source operand to a destination directory named by the directory operand.  The
     destination path for each operand is the pathname produced by the concatenation of the last operand, a slash, and the final pathname compo-
     nent of the named file.

     The following options are available:

     -r    If source designates a directory, /usr/bin/CpMac copies the directory and the entire subtree connected at that point.  This option also
	   causes symbolic links to be copied, rather than indirected through, and for /usr/bin/CpMac to create special files rather than copying
	   them as normal files.  Created directories have the same mode as the corresponding source directory, unmodified by the process' umask.

     -p    Causes /usr/bin/CpMac to preserve in the copy as many of the modification time, access time, file flags, file mode, user ID, and group
	   ID as allowed by permissions.

     -mac  Allows use of HFS-style paths for both source and target.  Path elements must be separated by colons, and the path must begin with a
	   volume name or a colon (to designate current directory).

NOTES

     The /usr/bin/CpMac command does not support the same options as the POSIX cp command, and is much less flexible in its operands.  It cannot
     be used as a direct substitute for cp in scripts.

     As of Mac OS X 10.4, the cp command preserves metadata and resource forks of files on Extended HFS volumes, so it can be used in place of
     CpMac.  The /usr/bin/CpMac command will be deprecated in future versions of Mac OS X.
