Looking for help for sort, I learned that for sorting numbers I use:
sort -n
but it seems that that is not enough when you have numbers like 0.2000E+7 for example, sort -n will not worry about the E+7 part, and will just sort the numbers like 0.2000.

Sort::Key::Natural(3pm) User Contributed Perl Documentation Sort::Key::Natural(3pm)
NAME
Sort::Key::Natural - fast natural sorting
SYNOPSIS
use Sort::Key::Natural qw(natsort);
my @data = qw(foo1 foo23 foo6 bar12 bar1
foo bar2 bar-45 foomatic b-a-r-45);
my @sorted = natsort @data;
print "@sorted
";
# prints:
# b-a-r-45 bar1 bar2 bar12 bar-45 foo foo1 foo6 foo23 foomatic
use Sort::Key::Natural qw(natkeysort);
my @objects = (...);
my @sorted = natkeysort { $_->get_id } @objects;
DESCRIPTION
This module extends the Sort::Key family of modules to support natural sorting.
Under natural sorting, strings are split at word and number boundaries, and the resulting substrings are compared as follows:
o numeric substrings are compared numerically
o alphabetic substrings are compared lexically
o numeric substrings come always before alphabetic substrings
Spaces, symbols and non-printable characters are only considered for splitting the string into its parts but not for sorting. For instance
"foo-bar-42" is broken in three substrings "foo", "bar" and 42 and after that the dashes are ignored.
Note, that the sorting is case sensitive. To do a case insensitive sort you have to convert the keys explicitly:
my @sorted = natkeysort { lc $_ } @data
Also, once this module is loaded, the new type "natural" (or "nat") will be available from Sort::Key::Maker. For instance:
use Sort::Key::Natural;
use Sort::Key::Maker i_rnat_keysort => qw(integer -natural);
creates a multikey sorter "i_rnat_keysort" accepting two keys, the first to be compared as an integer and the second in natural descending
order.
There is also an alternative set of natural sorting functions that recognize floating point numbers. They use the key type "natwf"
(abreviation of "natural_with_floats").
FUNCTIONS
the functions that can be imported from this module are:
natsort @data
returns the elements of @data sorted in natural order.
rnatsort @data
returns the elements of @data sorted in natural descending order.
natkeysort { CALC_KEY($_) } @data
returns the elements on @array naturally sorted by the keys resulting from applying them "CALC_KEY".
rnatkeysort { CALC_KEY($_) } @data
is similar to "natkeysort" but sorts the elements in descending order.
natsort_inplace @data
rnatsort_inplace @data
natkeysort_inplace { CALC_KEY($_) } @data
rnatkeysort_inplace { CALC_KEY($_) } @data
these functions are similar respectively to "natsort", "rnatsort", "natsortkey" and "rnatsortkey", but they sort the array @data in
place.
$key = mkkey_natural $string
given $string, returns a key that can be compared lexicographically to another key obtained in the same manner, results in the same
order as comparing the former strings as in the natural order.
If the argument $key is not provided it defaults to $_.
natwfsort @data
rnatwfsort @data
natkeywfsort { CALC_KEY($_) } @data
rnatkeywfsort { CALC_KEY($_) } @data
natwfsort_inplace @data
rnatwfsort_inplace @data
natkeywfsort_inplace { CALC_KEY($_) } @data
rnatkeywfsort_inplace { CALC_KEY($_) } @data
mkkey_natural_with_floats $key
this ugly named set of functions perform in the same way as its s/natwf/nat/ counterpart with the difference that they honor floating
point numbers embeded inside the strings.
In this context a floating point number is a string matching the regular expression "/[+-]?d+(.d*)?/". Note that numbers with an
exponent part (i.e. "1.12E-12") are not recognized as such.
Note also that numbers without an integer part (i.e. .2 or "-.12") are not supported either.
