Date reformatting
I currently have the following file containing sample values for a number of dates:
Code:
Loc1 04 Jan 2007 0.95 0.9532
Loc1 05 Jan 2007 0.95 0.9513
Loc1 06 Jan 2007 0.95 0.9535

This continues for all months of the year and spans across several years.

I am trying to reformat the dates so that they become mysql-friendly, ie to yyyy-mm-dd

Firstly, is there an easier way to translate the months than this?
Code:
sed -i '' -e 's/ Jan /-01-/' file.dat
sed -i '' -e 's/ Feb /-02-/' file.dat
sed -i '' -e 's/ Mar /-03-/' file.dat
sed -i '' -e 's/ Apr /-04-/' file.dat
sed -i '' -e 's/ May /-05-/' file.dat
sed -i '' -e 's/ Jun /-06-/' file.dat
sed -i '' -e 's/ Jul /-07-/' file.dat
sed -i '' -e 's/ Aug /-08-/' file.dat
sed -i '' -e 's/ Sep /-09-/' file.dat
sed -i '' -e 's/ Oct /-10-/' file.dat
sed -i '' -e 's/ Nov /-11-/' file.dat
sed -i '' -e 's/ Dec /-12-/' file.dat

Secondly, from there I reformat the dates from dd-mm-yyyy to yyyy-mm-dd as follows:
Code:
sed -i '' -e "s#\(..\) \(..\) \(....\)#\3-\2-\1#" file.dat

Perhaps all commands can be combined into one, preferably using sed or tr?

Thank you in advance

load_datafile

load_datafile(3alleg4)						  Allegro manual					    load_datafile(3alleg4)

NAME

       load_datafile - Loads a datafile into memory. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       DATAFILE *load_datafile(const char *filename);

DESCRIPTION

       Loads  a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate
       key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example:

	  /* Load the resources for our game. */
	  DATAFILE *dat = load_datafile("game.dat");
	  if (!dat)
	     abort_on_error("Couldn't load sound resources!");
	  /* Use resources. */
	  ...
	  /* Destroy them when we don't need them any more. */
	  unload_datafile(dat);

RETURN VALUE

       Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks.
