help need in filtering data

Hello Gurus,

Please help me out of the problem. I ve a input file as below
Code:
  input clock;
  input a; //reset all
  input [9:0] b;

  //input comment
  output c;
  output d;
  output [1:0] e;
  input   [4:0] f;
  //output comment

I need the output as follows:

Code:
\\Inputs
clock
a
b
f[4:0]
\\Outputs
c
d
e[1:0]

I tried with the following code:
Code:
gawk '\
  {
  gsub(/(^ *|^\t)/, "", $0) \\ for cutting one or more space OR tab
  if( match($0,/^input/) ){
          print $0 > "del1"
  }
  if( match($0,/^output/) ){
          print $0 > "del2"
  }
}' file

then merge del1 & del2 perhaps would give the output. then I need to delete the files del1 and del2.

Is there any other simple way ?Smilie

NAME
cfgetospeed(), cfsetospeed(), cfgetispeed(), cfsetispeed() - tty baud rate functions SYNOPSIS
DESCRIPTION
These functions set and get the input and output speed codes in the termios structure referenced by termios_p. The termios structure con- tains these speed codes representing input and output baud rates as well as other terminal related parameters. Setting the parameters on a terminal file does not become effective until is successfully called. returns the output speed code from the termios structure referenced by termios_p. sets the output speed code in the termios structure referenced by termios_p to speed. The speed code for a baud rate of zero, is used to termi- nate the connection. If is specified, the modem control lines are no longer asserted, which normally discon- nects the line. returns the input speed code from the termios structure referenced by termios_p. sets the input speed code in the termios structure referenced by termios_p to speed. RETURN VALUE
returns the output speed code from the termios structure referenced by termios_p. returns the input speed code from the termios structure referenced by termios_p. and return zero upon successful completion. Otherwise, they return -1 and set to indicate the error. ERRORS
and fail when the following condition is encountered: [EINVAL] The value of speed is outside the range of possible speed codes as specified in WARNINGS
and can be used to set speed codes in the termios structure that are not supported by the terminal hardware. SEE ALSO
