Sorting Difficulties
Hey guys,

I am sort of new to unix and I am having difficulty sorting. What I am trying to do is sort a particular field in reversed order and another field in alphabetic order to create a new file that looks like this:

MILLER,EDWARD AL 14 101293 9341
MOORE,HENRY 15 101297 9077
NGUYEN,LE HUU 13 101314 9576

*NOTE THAT THE SPACINGS ARE NOT DISPLAYED CORRECTLY; IT SHOULD BE ALL LINED UP

here is what I tried:

sort -r +0.20 -0.24 +0.00 -0.16 "input file" > "output file"

Basically, "+0.20 -0.24" represents the first two digit numbers that needs to be reversed and "+0.00 -0.16" represents the names that needs to be in alphabetic order.

can someone help me?

slapo-valsort

SLAPO-VALSORT(5)						File Formats Manual						  SLAPO-VALSORT(5)

NAME

       slapo-valsort - Value Sorting overlay to slapd

SYNOPSIS

       /etc/ldap/slapd.conf

DESCRIPTION

       The  Value Sorting overlay can be used with a backend database to sort the values of specific multi-valued attributes within a subtree. The
       sorting occurs whenever the attributes are returned in a search response.

       Sorting can be specified in ascending or descending order, using either numeric or alphanumeric sort methods.  Additionally,  a	"weighted"
       sort  can  be specified, which uses a numeric weight prepended to the attribute values.	The weighted sort is always performed in ascending
       order, but may be combined with the other methods for values that all have equal weights. The weight is specified by prepending an  integer
       weight  {<weight>} in front of each value of the attribute for which weighted sorting is desired. This weighting factor is stripped off and
       never returned in search results.

CONFIGURATION

       These slapd.conf options apply to the Value Sorting overlay.  They should appear after the overlay directive.

       valsort-attr <attribute> <baseDN> (<sort-method> | weighted [<sort-method>])
	      Configure a sorting method for the specified attribute in the subtree rooted at baseDN.  The sort-method may be one of alpha-ascend,
	      alpha-descend, numeric-ascend, or numeric-descend.  If the special weighted method is specified, a secondary sort-method may also be
	      specified. It is an error to specify an alphanumeric sort-method for an attribute with Integer or NumericString syntax, and it is an
	      error to specify a numeric sort-method for an attribute with a syntax other than Integer or NumericString.

EXAMPLES

	    database bdb
	    suffix dc=example,dc=com
	    ...
	    overlay valsort
	    valsort-attr member ou=groups,dc=example,dc=com alpha-ascend

FILES

       /etc/ldap/slapd.conf
	      default slapd configuration file
