Hi,
I need help to sort a file contents.
I am using sort -r option to basically reverse the comparison in descending order. However, i found out that my file is not sorted according, can anyone please help.
My data is something like:-
Hello world

1 LC
1 B
As you can see, it's already sorted by numerical order, how do I sort it again, breaking the ties by using the alphabetical order of the second column, but... (2 Replies)
Hi to all.
I'm trying to sort this with the Unix command sort.

I need to get this:

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.
Exapmle:
cat example.txt

Hello,
okey so my script is using 4 variables that are either empty or numbers in the following format:
NUMBER_1 NUMBER_2 NUMBER_3 NUMBER_4
So they're basically separated by a space and I need to echo the lowest number, so far I've been doing it like this:
echo "2 3 1 3" | tr " "... (6 Replies)
I would like to know how to sort version numbers, using bash or perl. I would like to sort file names that are program names with version numbers and extensions, such as hello-0.2.3.tar.gz and hello-0.10.3.tar.gz.
Version numbers of computer programs do not comply with the mathematical rule... (3 Replies)

I have files like this:

I want to extract the highest number. I have tried using

but then 9 would become higher than 14.
So how do I sort? (1 Reply)

sort::versions
Versions(3pm) User Contributed Perl Documentation Versions(3pm)NAME
Sort::Versions - a perl 5 module for sorting of revision-like numbers
SYNOPSIS
use Sort::Versions;
@l = sort { versioncmp($a, $b) } qw( 1.2 1.2.0 1.2a.0 1.2.a 1.a 02.a );
...
use Sort::Versions;
print 'lower' if versioncmp('1.2', '1.2a') == -1;
...
use Sort::Versions;
%h = (1 => 'd', 2 => 'c', 3 => 'b', 4 => 'a');
@h = sort { versioncmp($h{$a}, $h{$b}) } keys %h;
DESCRIPTION
Sort::Versions allows easy sorting of mixed non-numeric and numeric strings, like the 'version numbers' that many shared library systems
and revision control packages use. This is quite useful if you are trying to deal with shared libraries. It can also be applied to
applications that intersperse variable-width numeric fields within text. Other applications can undoubtedly be found.
For an explanation of the algorithm, it's simplest to look at these examples:
1.1 < 1.2
1.1a < 1.2
1.1 < 1.1.1
1.1 < 1.1a
1.1.a < 1.1a
1 < a
a < b
1 < 2
1.1-3 < 1.1-4
1.1-5 < 1.1.6
More precisely (but less comprehensibly), the two strings are treated as subunits delimited by periods or hyphens. Each subunit can contain
any number of groups of digits or non-digits. If digit groups are being compared on both sides, a numeric comparison is used, otherwise a
ASCII ordering is used. A group or subgroup with more units will win if all comparisons are equal. A period binds digit groups together
more tightly than a hyphen.
Some packages use a different style of version numbering: a simple real number written as a decimal. Sort::Versions has limited support for
this style: when comparing two subunits which are both digit groups, if either subunit has a leading zero, then both are treated like
digits after a decimal point. So for example:
0002 < 1
1.06 < 1.5
This won't always work, because there won't always be a leading zero in real-number style version numbers. There is no way for
Sort::Versions to know which style was intended. But a lot of the time it will do the right thing. If you are making up version numbers,
the style with (possibly) more than one dot is the style to use.
USAGE
The function "versioncmp()" takes two arguments and compares them like "cmp". With perl 5.6 or later, you can also use this function
directly in sorting:
@l = sort versioncmp qw(1.1 1.2 1.0.3);
The function "versions()" can be used directly as a sort function even on perl 5.005 and earlier, but its use is deprecated.
