Sure:
Code:
awk -F_ '                     # set field separator to underscore
  {
    A[$1 FS $2]++             # count the number of times $1 FS $2 occurs (field 1 and field2 separated by an underscore (for example "data_1")
  } 
END{
  for(i in A) print i, A[i]   # At the end print the results
}
'

NAME
curses_underscore, underscore, underend, wunderscore, wunderend -- curses underscore attribute manipulation routines LIBRARY
Curses Library (libcurses, -lcurses) SYNOPSIS
#include <curses.h> int underscore(void); int underend(void); int wunderscore(void); int wunderend(void); DESCRIPTION
These functions manipulate the underscore attribute on stdscr or on the specified window. The underscore() function turns on the underscore attribute on stdscr.

The wunderscore() and wunderend() functions are equivalent to underscore() and underend(), respectively, excepting that the attribute is manipulated on the window specified by win. The underscore() and underend() functions are equivalent to wattron(A_UNDERLINE) and wattroff(A_UNDERLINE), respectively. RETURN VALUES
These functions always return 1. SEE ALSO
curses_attributes(3), curses_standout(3) STANDARDS
The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification. HISTORY
These functions first appeared in NetBSD 1.5. BSD
