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

extutils::command

ExtUtils::Command(3pm)					 Perl Programmers Reference Guide				    ExtUtils::Command(3pm)

NAME

       ExtUtils::Command - utilities to replace common UNIX commands in Makefiles etc.

SYNOPSIS

	 perl -MExtUtils::Command -e cat files... > destination
	 perl -MExtUtils::Command -e mv source... destination
	 perl -MExtUtils::Command -e cp source... destination
	 perl -MExtUtils::Command -e touch files...
	 perl -MExtUtils::Command -e rm_f files...
	 perl -MExtUtils::Command -e rm_rf directories...
	 perl -MExtUtils::Command -e mkpath directories...
	 perl -MExtUtils::Command -e eqtime source destination
	 perl -MExtUtils::Command -e test_f file
	 perl -MExtUtils::Command -e test_d directory
	 perl -MExtUtils::Command -e chmod mode files...
	 ...

DESCRIPTION

       The module is used to replace common UNIX commands.  In all cases the functions work from @ARGV rather than taking arguments.  This makes
       them easier to deal with in Makefiles.  Call them like this:

	 perl -MExtUtils::Command -e some_command some files to work on

       and NOT like this:

	 perl -MExtUtils::Command -e 'some_command qw(some files to work on)'

       For that use Shell::Command.

       Filenames with * and ? will be glob expanded.

   FUNCTIONS
       cat
	       cat file ...

	   Concatenates all files mentioned on command line to STDOUT.

       eqtime
	       eqtime source destination

	   Sets modified time of destination to that of source.

       rm_rf
	       rm_rf files or directories ...

	   Removes files and directories - recursively (even if readonly)

       rm_f
	       rm_f file ...

	   Removes files (even if readonly)

       touch
	       touch file ...

	   Makes files exist, with current timestamp

       mv
	       mv source_file destination_file
	       mv source_file source_file destination_dir

	   Moves source to destination.  Multiple sources are allowed if destination is an existing directory.

	   Returns true if all moves succeeded, false otherwise.

       cp
	       cp source_file destination_file
	       cp source_file source_file destination_dir

	   Copies sources to the destination.  Multiple sources are allowed if destination is an existing directory.

	   Returns true if all copies succeeded, false otherwise.

       chmod
	       chmod mode files ...

	   Sets UNIX like permissions 'mode' on all the files.	e.g. 0666

       mkpath
	       mkpath directory ...

	   Creates directories, including any parent directories.

       test_f
	       test_f file

	   Tests if a file exists.  Exits with 0 if it does, 1 if it does not (ie.  shell's idea of true and false).

       test_d
	       test_d directory

	   Tests if a directory exists.  Exits with 0 if it does, 1 if it does not (ie. shell's idea of true and false).

       dos2unix
	       dos2unix files or dirs ...

	   Converts DOS and OS/2 linefeeds to Unix style recursively.

SEE ALSO

       Shell::Command which is these same functions but take arguments normally.
