If you can help me I will bi very very happy !

script
 

just save the following with some file name, give it execute permissions and it will do the job for u..

########################
#!/bin/sh
if [ -a /tmp/hello ]
then
b=`cat /tmp/hello | cut -f2 -d:`
b=`expr $b + 1`
echo sn:$b > /tmp/hello
else
a=1
echo sn:$a > /tmp/hello
fi
########################

/tmp/hello is the file where u need the the "sn:1", "sn:2" to be there.

happy scripting..
