copy directories and files recursively using C shell or bash shell

[kumarboston]

Hi all,
I am trying to copy couple of directories and their files to another place. Each directory have 25-30 files and numbered accordingly, the problem I am facing is, I have to copy files numbered from 4-22 only and leave rest all.
I have written a code but its only copying one directory and its files and not others.
Overall /test1/step_1/prodinit_1....30 and I want to copy to /test2/step_1/prodinit_4...22

#!/bin/csh -f
 
set dir1 = /home/rr/copy/test1
set dir2 = /home/rr/copy/test2
 
set step = 1
set stepmax = 30
set num  = 4
set nummax = 22
 
    mkdir $dir2/step_${step}
    echo $dir2/step_${step}
 
while ($step < 30)
   cd $dir2/step_${step}
   cp -r $dir1/step_${step}/prodinit_${num}*.* $dir2/step_${step}
   echo "Copying file .."
   @ num = ${num} + 1
   if ($num == $nummax ) exit
   cd ..
end
 

I am new to shell programming and any help will be appreciated.

Thanks
Kumar

You can make use of for and while loop for this

DIR="dir1 dir2 dir3 ..."
dest_dir="directory u need"
for dir in $DIR
do
   $i=4
   while [ $i -lt 30 ]
   do
       cp $d/$i".txt" $dest
       $i=`expr $i + 1`
   done
done
 

Start with this pseudo code
