There are some "sort" intrinsics to be considered and i think you haven't covered them all yet. This might not have any impact on your test file, but may well change the sorting order in another sample.
Lets see:
The default behavior of "sort" is to sort from the field/position given in te argument to the "-k" option to the end of line. That means:
will sort on field 2 first, in case f2 is equal on field 3, if this is equal too on field 4, etc. to the end of line. As you want to search on a last name - first name basis you have to state that:
You are lucky that you use only full fields, because it is possible to base sorting order on a sub-field starting at the n-th character of a certain field. Alas, character-numbering is sometimes 1-based and sometimes zero-based, depending on "-t" or "-b" being used - as i learned myself recently the hard way.
I hope this helps.

Very close... According to the standards (and the sort utilities I've used tend to follow the standards pretty closely), what you said about sort -k 2 is exactly correct. But, sort -k 2,2 sorts on the 2nd field and if two or more lines compare equal on that field, the entire line is used as the secondary sort key. So sort -k 2,2 performs exactly the same sort as sort -k 2,2 -k 1,1.
Hi to all.
I'm trying to sort this with the Unix command sort.
user1:12345678:3.5:2.5:8:1:2:3
user2:12345679:4.5:3.5:8:1:3:2

user4:12345670:5.5:2.5:5:3:2:1
user5:12345671:2.5:5.5:7:2:3:1
I need to get this:

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:

Hi everyone,
I have a text file with this following format:
w m a c G

I'd like to sort it to a file with the following format (same number of lines, same number of fields, but all fields are sorted alphabetically)
G V a b c
+ d e f
+ m t w y

SORT(1) User Commands SORT(1)NAME
sort - sort lines of text files
SYNOPSIS
sort [OPTION]... [FILE]...
DESCRIPTION
Write sorted concatenation of all FILE(s) to standard output.
Mandatory arguments to long options are mandatory for short options too. Ordering options:
-b, --ignore-leading-blanks
ignore leading blanks
-d, --dictionary-order
consider only blanks and alphanumeric characters
-f, --ignore-case
fold lower case to upper case characters
-g, --general-numeric-sort
compare according to general numerical value
-i, --ignore-nonprinting
consider only printable characters
-M, --month-sort
compare (unknown) < `JAN' < ... < `DEC'
-n, --numeric-sort
compare according to string numerical value
-r, --reverse
reverse the result of comparisons
Other options:
-c, --check
check whether input is sorted; do not sort
-k, --key=POS1[,POS2]
start a key at POS1, end it at POS2 (origin 1)
-m, --merge
merge already sorted files; do not sort
-o, --output=FILE
write result to FILE instead of standard output
-s, --stable
stabilize sort by disabling last-resort comparison
-S, --buffer-size=SIZE
use SIZE for main memory buffer
-t, --field-separator=SEP
use SEP instead of non-blank to blank transition
-T, --temporary-directory=DIR
use DIR for temporaries, not $TMPDIR or /tmp; multiple options specify multiple directories
-u, --unique
with -c, check for strict ordering; without -c, output only the first of an equal run
-z, --zero-terminated
end lines with 0 byte, not newline
--help display this help and exit
--version
output version information and exit
POS is F[.C][OPTS], where F is the field number and C the character position in the field. OPTS is one or more single-letter ordering
options, which override global ordering options for that key. If no key is given, use the entire line as the key.
SIZE may be followed by the following multiplicative suffixes: % 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.
With no FILE, or when FILE is -, read standard input.
*** WARNING *** The locale specified by the environment affects sort order. Set LC_ALL=C to get the traditional sort order that uses
native byte values.
