Thanks For the Gyaan ... Smilie
Actually The Timestamp is appended to the file by oracle at time of creation.

Care to enlighten this a bit? are you talking about the timestamp in the filename that is already "sortable"..?

Hi Vgersh,

I tried the code snippet you had given
I got an error When i tried to execute the same

cat.sh[6]: nawk: not found.

What do i need to do in order to run the script.

When i tried to execute the snippet ghostdog74 had posted .

[90] % sh ack.sh
awk: Function mktime is not defined.
The input line number is 1. The file is Ack_to_MDS_20070809141151.xml.
The source line number is 10.

btw How do we change the program without using the mktime ?

mktime is GNU awk specific so if your awk version is not, then you can't use it.

yes. the '20070809141159' in the 'Ack_to_MDS_20070809141159.xml' is perfectly sortable by. Furthermore, the timestamp format (according to the OP) is: 'YYYYMMDDHHMMSS'.

use either 'awk' or 'gawk' (if you have one) instead of 'nawk'
