I finally found it myself. For those interested... Here are two scripts in batch  
1- gets all the indices names from elasticsearch and stores them in a file  
curl -HContent-Type:application/json -XGET localhost:9200/\_cat/indices/?h=index\>indices.txt

2- Creates new indices name-based on the existing indices  
for /f "tokens=\*" %%a in (indices.txt) do (  
curl -HContent-Type:application/json -XPUT localhost:9200/"%%a-new\_one"  
)

And this is the hole script in bash (that I didn't tested):

#!/bin/bash

liste\_indexs=`curl -HContent-Type:application/json -XGET localhost:9200/_cat/indices \> indices.txt`

for index in $liste\_indexs; do  
curl -HContent-Type:application/json -XPUT localhost:9200/"$index-new\_one"  
done
