Code:
traceroute X.X.X.X | awk 'BEGIN{ORS=" "}{if(NR==1)print $2,$4;else print $4;}'

You may pipe a sed command to remove the [ and ] brackets...

You can remove the square brackets in the same awk; added a RS at the end (not sure if needed):
Code:
awk 'BEGIN{ORS=" "}{gsub(/[][]/,"",$4); if(NR==1)print $2,$4;else print $4}END{print RS}' infile
192.168.1.1 AS28513 AS65534 AS5089 AS5089 AS5089 AS5089 AS5089 AS5089 AS174

Edit:
Sorry, just noticed you wanted also to remove duplicates and a sort too.

Please post the script which does the "traceroute" making it clear what Operating System you have and what Shell you are using.

The syntax for "traceroute" and the processing a "traceroute" output varies considerably. Many versions of the program output part of the output to STDOUT and part to STDERR.

The syntax for "awk", "sort" etc. also varies.

Hi, thanks for your urgent help, the traceroute is same as usual one.....traceroute6 -A ::1
But i discovered some repetition of some ASes along each line;

to (2001:1ba0:2a0:5965:0:30:14:1), AS786 AS786 AS786 AS786 AS786 AS786 AS786 * AS29208 AS29208 AS29208 AS29208 AS29208
to (2001:da8:208:100::121), AS786 AS786 AS786 AS786 AS786 AS786 AS20965 AS20965 AS20965 * * * * * * * * * * * * * * * * * * * * *

how can I sort it out to avoid repetitions of AS number along each line?
thanks

(I guess this is some Linux variant with some version of traceroute6).
