Change date format
Hi guys,
I have a text file with lots of lines like this:

MCOGT23R27815 27/07/07 27/05/09
SO733AM0235 30/11/07 30/11/10
NL123403N 04/03/08 04/03/11
0747AM7474 04/04/08 04/04/11

I want to change each line so the date format looks like this:

MCOGT23R27815 07/07/27 09/05/27
SO733AM0235 07/11/30 10/11/30
NL123403N 08/03/04 11/03/04
0747AM7474 08/04/04 11/04/04

Thanks..
note:this is on a Solaris10 system

Thanks for that.
One thing I forgot to mention is that the delimiter is not a space, it is a tab

Code:
perl -ple 's|(^\S+\s+)(\d{2})/(\d{2})/(\d{2}\s+)(\d{2})/(\d{2})/(\d{2})|\1\3/\2/\4\6/\5/\7|;' yourfile

For a tab:

Code:
perl -ple 's|(^\S+\t)(\d{2})/(\d{2})/(\d{2}\t)(\d{2})/(\d{2})/(\d{2})|\1\3/\2/\4\6/\5/\7|;' yourfile
