I have tried the below command, but its not working.

awk '{ l=substr($1,1,5); t= substr($1,6,10); NR=NR+1; k = substr($1,6,10) ; m=substr($1,1,5); if ( t == k) { p = m-l; if(p>1) for (i=1; i<(p-1); i++){z= l+i; print t z }}}' input_file

Pls help me

if your range is defined by consecutive line then this will work..

Code:

awk '{low=$0;getline}{for(i=low+1;i<$0;i++){print i}}' filename

Thanks vidyadhar,
