Picking the latest file based on a timestamp for a Dynamic file name
Hi ,

I did the initial search but could not find what I was expecting for.

Code:
15606Always_9999999997_20160418.xml
15606Always_9999999998_20160418.xml
15606Always_9999999999_20160418.xml
9819Always_99999999900_20160418.xml
9819Always_99999999911_20160418.xml

Above is the list of files I receive.

The file name is started with a key value and its changes.

I need to pick the latest file based on the seconds (_99999999911_) in the file name for each key value.

The result would be

Code:
15606Always_9999999999_20160418.xml
9819Always_99999999911_20160418.xml

I have script to select if the file name pattern does not change .. But in my case the key value is present in the starting of the file name.

Any help would be appreciated.


Thank you

evolvotron_mutate

EVOLVOTRON_MUTATE(1)						    Evolvotron						      EVOLVOTRON_MUTATE(1)

NAME

       evolvotron_mutate - Render an evolvotron function tree to an image.

SYNOPSIS

       evolvotron_mutate < function_in.xml > function_out.xml

       evolvotron_mutate -g > function_out.xml

DESCRIPTION

       evolvotron_mutate either mutates an existing image function (saved to an XML file), or (with the -g option) creates a new image function.

       The mutation parameters and function weightings are the same as used by evolvotron in its default reset state.

       See the evolvotron user manual (accessible from the evolvotron application's Help menu) for more information on image functions.

COMMANDLINE OPTIONS

       -g   Specifies that no function should be read from standard input.  The output function is created at random.

EXAMPLES

       evolvotron_mutate -g | tee function0.xml | evolvotron_render function0.ppm

       evolvtron_mutate < function0.xml > function1.xml
