    AT1G01060    AT1G01070    1.214972

Expected Output

Code:
    AT1G01020    AT1G01010    -1.90043
    AT1G01070    AT1G01060    1.214972
    AT1G01073    AT1G01070    0.790549

If you need to display and unique fields
then the result should be
Code:
AT1G01070 AT1G01060 -1.204241
AT1G01060 AT1G01070 1.214972
AT1G01020 AT1G01010 -1.90043
AT1G01073 AT1G01070 0.790549

and if don't
Code:
AT1G01070 AT1G01060 -1.204241
AT1G01020 AT1G01010 -1.90043

Is the solution suitable for you with the 'awk' tool?

--- Post updated at 17:40 ---

Code:
uniq -Dw 26 file |
awk '
NR==1 {next}
{if(abs(A[$1 FS $2]) < abs($3)) A[$1 FS $2] = $3}
END {for(i in A) print i, A[i]}
func abs(x) { return (x<0) ? x*-1 : x }'

awk '
NR==1 {next}
{if(abs(A[$1 FS $2]) < abs($3)) A[$1 FS $2] = $3}
END {for(i in A) print i, A[i]}
func abs(x) { return (x<0) ? x*-1 : x }' file

irsend

IRSEND(1)							   User Commands							 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
