the 2nd column takes the last colon, and the 3rd and 4th columns the contents of the square brackets.

Sed:

Sed ' s/://;s/ip\[\ (. *\) \]/\1/;s/\].*\[//' Test

Python:

#!/usr/bin/env pythonimport refile = open (' Test ') done = 0while not  Done:        line = file.readline ()          if line !=  ':                 line = line.strip (' \ n ')                  this_line_list = line.split ('   ')                 zz1  = re.compile (' [0-9]{2}:[0-9]{2}:[0-9]{2} ')                  zz2 = re.compile (' [0-9]{1,3}.[ 0-9]{1,3}. [0-9] {1,3}. [0-9] {1,3} ')                 zz3  = re.compile (' [0-9]{1,} ') &NBsp;               pp1 =  Re.findall (zz1,this_line_list[1])                  pp2 = re.findall (zz2,this_line_list[2])                  pp3 = re.findall (Zz3,this_line_list[3])                 print  '%s  %s %s %s '  %  (this_line_list[0],pp1[0],pp2[0],pp3[0])          else:                 done = 1file.close ()
