Code Sort date time in ascending order
Hi,

i had a data block (coming from pipe from other codes) as:
Code:
H  YF_CO.dat  77164  11/17/2013 04:00:02  731374590.96  1  1  731374590.96  76586  77164  578  2988  Y
H  YF_CO.dat  77164  11/17/2013 04:00:07  731374590.96  1  4  731374590.96  76586  77164  578  2988  Y
H  YF_CO.dat  77178  11/17/2013 04:00:07  731374590.96  2  4  731374590.96  76600  77178  578  3002  Y

i wanted to sort the records along 4th and 5th column in ascending order of date and time using sort(or any other in that matter). I came a long way thru my code only at the end to realize that the way i am using sort ( sort -nk 5, i didn't try to sort the date but would be great if i cud take that into account too ) does not give me desired result. My constraint is that the solution must be as small as possible( great if i can use it to get input from a pipe and redirect to a text file) so that my already sizable code doesn't grow larger. I am using ksh shell in Solaris. I would appreciate any help in that matter.

Thanks

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.
