According to the standards, the command:
sorts lines in file into increasing order evaluating field 2 and all fields following it as numeric values and if fields 2 to the end of the line compare equal to another line it then compares field 3 and all fields following it as numeric values and if two lines still compare as equal it then compares the entire line as a string of bytes to determine which line will come first.
sorts lines in file into increasing order evaluating the 2nd and 3rd fields as numeric values and if the numeric values of those two fields are the same when comparing two lines the entire line will be compared as a string of bytes to determine which line will come first.
If what you are trying to do is sort numeric values in fields 2 and 3 in file and only keep one line in cases when there are multiple lines with identical numeric values in those two fields, you would want to use:
if field 2 is your primary sort key and field 3 is your secondary key or:
if field 3 is your primary sort key and field 2 is your secondary key.

Hi,
I am using some codes that have been ported from unix to linux, and now the sorting no longer results in the desired ordering. I'm hoping to find a way to mimic the unix sort command in linux. The input file is structured the following:

To make it easier, i gave following example. It is not homework or classwork. Instead, i have a huge csv file dump from tsql with 15 columns and around 300 rows. I was able to extract content that needs to be really converted. Here is the extract:

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-jn m Join on the mth field of file n. If n is missing, use the mth field in each file.
-o list
Each output line comprises the fields specified in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
