Hello,
I have a data format as follows:
Ind1 0 1 2
Ind1 0 2 1
Ind2 1 1 0
Ind2 2 2 0
I want to use AWK to have this output:
Ind1 00 12 21
Ind2 12 12 00
That is to merge each two rows with the same row names.
Thank you very much in advance for your help. (8 Replies)

file::type
File::Type(3) User Contributed Perl Documentation File::Type(3)NAME
File::Type - determine file type using magic
SYNOPSIS
my $ft = File::Type->new();
# read in data from file to $data, then
my $type_from_data = $ft->checktype_contents($data);
# alternatively, check file from disk
my $type_from_file = $ft->checktype_filename($file);
# convenient method for checking either a file or data
my $type_1 = $ft->mime_type($file);
my $type_2 = $ft->mime_type($data);
DESCRIPTION
File::Type uses magic numbers (typically at the start of a file) to determine the MIME type of that file.
File::Type can use either a filename, or file contents, to determine the type of a file.
METHODS
new
Returns a new File::Type object.
mime_type($argument)
Takes either data or a filename, determines what it is, and passes the argument through to the relevant method below. If the argument is a
directory, returns undef.
checktype_filename($filename)
Opens $filename (if possible; if not, returns undef) and returns the MIME type of the file.
checktype_contents($data)
Matches $data against the magic database criteria and returns the MIME type of the file.
TODO
* Add additional magic match criteria
BUGS
None known.
NOTES
Some magic definitions in the mime-magic file used in the creation of this module vary from those in other apps (eg image/x-png not
image/png).
SEE ALSO
File::MMagic and File::MimeInfo perform the same job, but have a number of problems that led to the creation of this module.
File::MMagic inlines a copy of the magic database, and uses a DATA filehandle, which causes problems when running under mod_perl.
File::MimeInfo uses an external magic file, and relies on file extensions rather than magic to determine the mime type.
As a result, File::Type uses a seperate module and script to create the code at the core of this module, which means that there is no need
to include a magic database at all, and that it is safe to run under mod_perl.
File::Type::Builder, which generates the code at the heart of this module.
ACKNOWLEDGMENTS
File::Type is built from a mime-magic file from cleancode.org. The original can be found at
http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-magic.mime?rev=1.1.1.1 <http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-
