hi,
I'm doing some changes already.
I'm running the test now with printf and trying to figure the amount of memory for sort (1 or 2 or 3 Gb :P)
Code:

I wanted to say that hard disk is working in the maximum but there is memory and processor available! I will start using a bit of the available memory for sort.
I planning on doing gunzip to the files in the biggining. This way i can send all the files into the same script and i just need to do an if for each file, like: IF FILENAME== /*line*/ "line code". this way i can send the result to sort instead of writting the "final" file.

Hi,
I have got a 9.3GB file and it is taking 1h 8min to sort file using the following code:

Is there a faster way of doing it please?
Thanks

sort
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.

- the server as a I/0 charge very big so i should be able to do all the process only in memory (there are processors without charge and memory).
