    Thanks Tabstop and rags to riches.

    1 very stupid question
    sort -t ':' +0 -1 -n +1 -2 +2 -3 -o list list
    will the Field 1 that is 2008-07-17| be sorted in numerical order?
    I always thought the parameter -n is only meant for fields mentioned preceding it.that is +0 -1 ?

    000|2008-07-17|556543|RTJ|35-RTGJ|EYT
    465|2008-11-10|567789|GHJ|45-DGHH|ETU
    533|2008-09-06|567789|GHJ|45-DGHH|ETU
    Then
    sort -t ':' +0 -1 +1 -2 -n +2 -3 -o list list would mean the same thing.I also gotta learn that the field 000 is Field 0.
    Is it the same case with awk '|' print $1 on the line 000|2008-07-17|556543|RTJ|35-RTGJ|EYT .Will it print 2008-07-17?
    Thanks a lot,

    You don't want field 1 (the dates) sorted in numerical order. It's currently sorted in lexicographic (alphabetical) order, which is convenient since that automatically sorts yyyy-mm-dd in proper chronological order.
