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

unknown

UNKNOWN(1)						      General Commands Manual							UNKNOWN(1)

NAME

       unknown - identify possible genotypes for unknowns

SYNOPSIS

       A program to rapidly identify which genotypes are possible for individuals typed as unknowns in the input pedigree.

       unknown [ -cl ]

DESCRIPTION

       unknown infers possible genotypes and mating combinations for parents with unknown genotypes for ilink(1), mlink(1) and linkmap(1).

OPTIONS

       -c     Use conditional allele frequencies.

       -l     Choose a good set of loop breakers automatically.

RETURN VALUE

       0     Successful completion

ERRORS

       10    File not found
       255   Failure

EXAMPLES

       Normally, unknown(1) is run immediately prior to its sister programs, ilink(1), mlink(1) and linkmap(1), like this:

       unknown
       mlink

FILES

       unknown(1) reads the two files pedfile.dat and datafile.dat as its own input and produces various temporary files that are used as input to
       the next program. These temporary files are ipedfile.dat, upedfile.dat, speedfile.dat and newspeedfile.dat.

NOTES

       unknown(1) is part of the FASTLINK package, which is a re-implementation of the LINKAGE suite  of  computer  tools  that  help  investigate
       genetic linkage as first proposed G.M. Lathrop, J.M. Lalouel, C. Julier, and J. Ott.
