Sorting with multiple numeric keys
Data I want to sort :-
1 10 jj Y
2 100 vv B
19 5 jj A
1 11 hq D
3 8 op X
44 78 ds GG
1 8 hq D
and want to sort based on the first 2 columns - which hold numeric values.
Am using :
cat filename | sort -nk 1,2
But the result is :-
1 10 jj Y
1 11 hq D
1 8 hq D
2 100 vv B
3 8 op X
19 5 jj A
44 78 ds GG
sort uses the first column as a key but does not seem to use the 1nd column as the second key.
Am doing something wrong ?

Hi,
I would like to do the following sorting, but the output is not what i expected. Why 222 and 2222 are not at the last two elements of array?

Can you guys pls take a look at this.
I need to sort this list of numbers as follows:
2nd col first, then 1st col, then 3rd col, all in reverse (highest to lowest).
I'm doing this:

Any idea... (0 Replies)

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
