The best way to see the difference is to diff both files.
diff ID_file1.txt ID_file2.txt says the files differ.
To find out the difference, I issued an hexdump on both files and we see the difference quite easily in the end of each string:
As you can see, there is an 0xd followed by 0xa in the end of ID_file2.txt and just a 0xa in ID_file1.txt
PS: the output of hexdump should be read as follows:
1234 5678 9123 4567 -> 34, 12, 78, 56, 23, 91, 67, 45.
So, 6f43 746e 6769 0d31 430a 6e6f 6974 3267 is 0x43 0x6f 0x6e 0x74 0x69 0x67 0x31 0xd 0xa 0x43 0x6f ...
yeah.. thanks for clarifying )) Excuse my ignorance - is this difference with defining line ends only? does that mean the (e.g. perl) scripts will treat such lines as different? If yes, how can the endings be fixed?
I have a file:
Fred
Fred
Fred
Jim
Fred
Jim
Jim
If sort is executed on the listed file, shouldn't the output be?:
Fred
Fred
Fred
Fred
Jim

Hi
Just wondering whether or not I can remove duplicated lines without sort
For example, I use the command who, which shows users who are logging on. In some cases, it shows duplicated lines of users who are logging on more than one terminal.
Normally, I would do
who | cut -d" " -f1 |... (6 Replies)
So, I have a file that has some duplicate lines. The file has a header line that I would like to keep at the top.
I could do this by extracting the header from the file, 'sort -u' the remaining lines, and recombine them. But they are quite big, so if there is a way to do it with a single... (1 Reply)

hello, I have a large file (about 1gb) that is in a file similar to the following:

Hello all,
Need to pick your brains,
I have a 10Gb file where each row is a name, I am expecting about 50 names in total. So there are a lot of repetitions in clusters.
So I want to do a
sort -u file
Will it be considerably faster or slower to use a uniq before piping it to sort... (3 Replies)

Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3)User Contributed Perl DocumentatioPerl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3)NAME
Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen - Write "open $fh, q{<}, $filename;" instead of "open $fh, "<$filename";".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The three-argument form of "open" (introduced in Perl 5.6) prevents subtle bugs that occur when the filename starts with funny characters
like '>' or '<'. The IO::File module provides a nice object-oriented interface to filehandles, which I think is more elegant anyway.
open( $fh, '>output.txt' ); # not ok
open( $fh, q{>}, 'output.txt' ); # ok
use IO::File;
my $fh = IO::File->new( 'output.txt', q{>} ); # even better!
It's also more explicitly clear to define the input mode of the file, as in the difference between these two:
open( $fh, 'foo.txt' ); # BAD: Reader must think what default mode is
open( $fh, '<', 'foo.txt' ); # GOOD: Reader can see open mode
This policy will not complain if the file explicitly states that it is compatible with a version of perl prior to 5.6 via an include
statement, e.g. by having "require 5.005" in it.
CONFIGURATION
This Policy is not configurable except for the standard options.
NOTES
There are two cases in which you are forced to use the two-argument form of open. When re-opening STDIN, STDOUT, or STDERR, and when doing
a safe pipe open, as described in perlipc.
