something to start with - a bit verbose...:
awk -f pedro.awk myFile
where pedro.awk is:
Code:
BEGIN {
  FS="[>;]"
  OFS=";"
}

function p(a, i)
{
   for(i in a)
     print ">" i, "*nr=" ln

}
/^>/ {p(out);ln=0;split("",out);next}
/[*]/  {idx=$2 OFS $3; out[idx]}
{ln++}
END {
  if (ln) p(out)
}

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
