Bash/awk and for loop to create a template
Source File:
Code:
google.cz http://czechrepublic.google.com/
http://czechrepublic.google.cz http://czechrepublic.google.com/
http://brno.google.cz http://brno.google.com/

Fail Code
Code:
root@arisvm ~/g] $ cat trya
rm -f ss
for i in a.txt
do
#b=`cat $i|awk '{print $1}'`
#c=`cat $i|awk '{print $2}'`
echo "server {"  >> ss
echo "          listen 80;"  >> ss
echo "          server_name  $(cat $i|awk '{print $1}'|head -1 ) "   >> ss
echo "  rewrite  ^/(.*)$   $(cat $i|awk '{print $2}' | head -1 )  permanent;"  >> ss
echo " } "  >> ss
done

output of fail code:
Code:
root@arisvm ~/g] $ cat ss
server {
          listen 80;
          server_name  google.cz
  rewrite  ^/(.*)$   http://czechrepublic.google.com/  permanent;
 }
root@arisvm ~/g] $


Desired Output:
Code:
server {
        listen 80;
        server_name google.cz;
        rewrite  ^/(.*)$ http://czechrepublic.google.com permanent;
        }
server {
        listen 80;
        server_name www.google.cz;
        rewrite  ^/(.*)$ http://czechrepublic.google.com permanent;
        }
server {
        listen 80;
        server_name czechrepublic.google.cz;
        rewrite  ^/(.*)$ http://czechrepublic.google.com permanent;
        }
server {
        listen 80;
        server_name brno.google.cz;
        rewrite  ^/(.*)$ http://brno.google.com permanent;
        }

Where do you extract the www.google.cz; ?
Code:
google.cz
czechrepublic.google.cz
brno.google.cz


Anyway, perhaps something like this would be close to a solution.
Code:
awk 'NF>1 {
        sub("http://", "", $1);
        print "server {";
        print "        listen 80;";
        print "        server_name", $1";";
        print "        rewrite  ^/(.*)$", $2, "permanent;";
        print "       }";
}' source_file

Starting from your "fail code", how would you like these adaptions:
Code:
while read SN RWT
        do      echo "server {"
                echo "  listen 80;"
                echo "  server_name  $SN"
                echo "  rewrite  ^/(.*)$   $RWT  permanent;"
                echo "  }"
         done <a.txt >ss
cat ss
server {
        listen 80;
        server_name  google.cz
        rewrite  ^/(.*)$   http://czechrepublic.google.com/  permanent;
        }
server {
        listen 80;
        server_name  http://czechrepublic.google.cz
        rewrite  ^/(.*)$   http://czechrepublic.google.com/  permanent;
        }
server {
        listen 80;
        server_name  http://brno.google.cz
        rewrite  ^/(.*)$   http://brno.google.com/  permanent;
        }

In addition to RudiC's suggestion, you can use ${SN#*://} instead of $SN to strip of the URL protocol part if present..

Guys, all is good, but i think.. you guys miss the 1st part and 2nd part of the output. the source file is constant..look closely above and see the output

source file look closely. the top 1 or the very top doesnt have http.compare to line number 2 and 3 and so forth.

Code:
google.cz http://czechrepublic.google.com/
http://czechrepublic.google.cz http://czechrepublic.google.com/
http://brno.google.cz http://brno.google.com/


Code:
server {
        listen 80;
        server_name google.cz;
        rewrite  ^/(.*)$ http://czechrepublic.google.com permanent;
        }
server {
        listen 80;
        server_name www.google.cz;
        rewrite  ^/(.*)$ http://czechrepublic.google.com permanent;
        }
server {
        listen 80;
        server_name czechrepublic.google.cz;
        rewrite  ^/(.*)$ http://czechrepublic.google.com permanent;
        }
server {
        listen 80;
        server_name brno.google.cz;
        rewrite  ^/(.*)$ http://brno.google.com permanent;
        }
