Top Forums Shell Programming and Scripting sort and semi-duplicate row - keep latest only Post 302274653 by radoulov on Thursday 8th of January 2009 04:35:46 AM

Something like this:

Code:
sort -t\| -k5nr infile|sort -t\| -uk2.1,2.3

With AWK (nawk or /usr/xpg4/bin/awk on Solaris):

Code:
awk -F\| 'END {
  for (k in r)
    print r[k]
	}
$NF > m[$2] {
  m[$2] = $NF
  r[$2] = $0 }
  ' file

Notice that the output will not be ordered by the second field.
