Thanks in advance.....
Hi,

Try this one,

Code:
nawk 'BEGIN{FS=" ";ORS=" ";}{split($2,a,"/");for(i=1;i<=NF;i++){if ( i == 2){print a[3]"/"a[2]"/"a[1];}else{print $i;}}print "\n"}' input_file

i assume,
$2=DateField

Input Sample:
Code:
SomeInfo 6/27/2011 12:00:00 AM
SomeInfo 6/27/2011 12:00:00 AM

Output:
Code:
 SomeInfo 2011/27/6 12:00:00 AM
 SomeInfo 2011/27/6 12:00:00 AM

Cheers,
RangaSmilie
