Try this:

Code:
awk -F'\t' '
/^aa/{                             # if line starts with aa
   if(f) close(f)                  # close already open file
   f=sprintf($1"%d.txt",++n)       # pre increment n, and set up variable f 
}
f {                                # if file name created
   $1=""                           # blank field #1
   $0=substr($0, 2)                # strip blank #1 field
   print >f;                       # write record/row/line to file
}
' OFS='\t' file

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
