HI all

004002004545454000001
041002004545222000002
006003008751525000003

006003008751142000005
004001005745745000006
i want to sort the file according to position 1-5 and secondary sort by
the last position of file 16-21
the result should be like this (file2) :
004002004545454000001
004001005745745000006
006003008751525000003
006003008751142000005
007003008751352000004
041002004545222000002
until today i needed to sort according to the 1-5 position .
my command is in a script and it looks like this :
sort /usr/tmp/file1 -o /usr/tmp/file2 -k 1,5 -S 22 (thelength is 22 because the file contain /012 character)
i don't know how to do the secondary sort
please help here
best regards

SORT(1) General Commands Manual SORT(1)
NAME
sort - sort a file of ASCII lines
SYNOPSIS
sort [-bcdfimnru] [-tc] [-o name] [+pos1] [-pos2] file ...
OPTIONS
-b Skip leading blanks when making comparisons
-c Check to see if a file is sorted
-d Dictionary order: ignore punctuation
-f Fold upper case onto lower case
-i Ignore nonASCII characters
-m Merge presorted files
-n Numeric sort order
-o Next argument is output file
-r Reverse the sort order
-t Following character is field separator
-u Unique mode (delete duplicate lines)
EXAMPLES
sort -nr file # Sort keys numerically, reversed
sort +2 -4 file # Sort using fields 2 and 3 as key
sort +2 -t: -o out # Field separator is :
sort +.3 -.6 # Characters 3 through 5 form the key
DESCRIPTION
Sort sorts one or more files. If no files are specified, stdin is sorted. Output is written on standard output, unless -o is specified.
The options +pos1 -pos2 use only fields pos1 up to but not including pos2 as the sort key, where a field is a string of characters delim-
ited by spaces and tabs, unless a different field delimiter is specified with -t. Both pos1 and pos2 have the form m.n where m tells the
number of fields and n tells the number of characters. Either m or n may be omitted.
