The sort utility is defined to work on text files. By definition, text files contain lines that are no longer than LINE_MAX bytes (including the line terminating <newline> character. You can check the value of LINE_MAX on your AIX system using the command:
The standards require LINE_MAX to be at least 2048 and that is the value supported on many UNIX systems.
I would guess that file1.dat contains lines longer than LINE_MAX bytes and you are seeing the undefined behavior that results when sort is asked to process a file that is not a text file.
You could use cut to split your input files with long lines into groups of files with shorter lines (copying the sort keys into each of the files), sort each of the files in the group, and then use paste to recreate your sorted output into a single file with long lines.
(Note, however, that sort -t "," +1 -2 will sort on the remainder of the input line if the sort key compares equal on some lines. So, if your sort keys are not unique, you need to duplicate enough fields to guarantee that you get the same sort order in all of your split files.)

Hi All,

I need to check whether newline character exists at the end of a file, if it does not then append it.

How is this possible to be done using sh instead of bash?
If I try something similar is SH, then inside... (3 Replies)

Hello all,
I have maybe a simple Problem - but I do not know to handle it.
All what I want, is to write a line to file without a newline at the end. It works with "echo -n" for all lines, but not for the last one. At the end of the file is always a "0a" (hex)
My small script:

locale(3pm) Perl Programmers Reference Guide locale(3pm)NAME
locale - Perl pragma to use or avoid POSIX locales for built-in operations
SYNOPSIS
@x = sort @y; # Unicode sorting order
{
use locale;
@x = sort @y; # Locale-defined sorting order
}
@x = sort @y; # Unicode sorting order again
DESCRIPTION
This pragma tells the compiler to enable (or disable) the use of POSIX locales for built-in operations (for example, LC_CTYPE for regular
expressions, LC_COLLATE for string comparison, and LC_NUMERIC for number formatting). Each "use locale" or "no locale" affects statements
to the end of the enclosing BLOCK.
Starting in Perl 5.16, a hybrid mode for this pragma is available,
use locale ':not_characters';
which enables only the portions of locales that don't affect the character set (that is, all except LC_COLLATE and LC_CTYPE). This is
useful when mixing Unicode and locales, including UTF-8 locales.
use locale ':not_characters';
use open ":locale"; # Convert I/O to/from Unicode
use POSIX qw(locale_h); # Import the LC_ALL constant
setlocale(LC_ALL, ""); # Required for the next statement
# to take effect
printf "%.2f
", 12345.67' # Locale-defined formatting
@x = sort @y; # Unicode-defined sorting order.
# (Note that you will get better
# results using Unicode::Collate.)
See perllocale for more detailed information on how Perl supports locales.
