I have a big file with 127 columns and 869 rows. What I am trying to do is to get the absolute value of all numbers in the file, and then get the maximum of each column.
If this was for one column it wouldn't be a problem, I would use:
But I don't know how could this be done in a larger file. Any help would be much appreciated.
Thanks!

Hi,
I am trying to find out how to get an absolute value for integer in ksh.
I tried using abs... but that doesn't work ! this is the workaround I did, but isn't there an inbuilt function to get absolute value for any variable !
Please help as i am new to unix :confused:

How would I get the absolute filename of a selected file...I want to control click...I already have the context menu all set to run a script...I just need to be able to get the file name of the file I control clicked on.
In windows it is as follows:

is there any function in unix which will convert a integer to absolute value with a single decimal point.
suppose x=15232
y=x/1024=14.875
i want y to be 14.8
Similarly if y=6.29452 it should come as 6.3 (3 Replies)

xml::filter::saxt
XML::Filter::SAXT(3) User Contributed Perl Documentation XML::Filter::SAXT(3)NAME
XML::Filter::SAXT - Replicates SAX events to several SAX event handlers
SYNOPSIS
$saxt = new XML::Filter::SAXT ( { Handler => $out1 },
{ DocumentHandler => $out2 },
{ DTDHandler => $out3,
Handler => $out4
}
);
$perlsax = new XML::Parser::PerlSAX ( Handler => $saxt );
$perlsax->parse ( [OPTIONS] );
DESCRIPTION
SAXT is like the Unix 'tee' command in that it multiplexes the input stream to several output streams. In this case, the input stream is a
PerlSAX event producer (like XML::Parser::PerlSAX) and the output streams are PerlSAX handlers or filters.
The SAXT constructor takes a list of hash references. Each hash specifies an output handler. The hash keys can be: DocumentHandler, DTDHan-
dler, EntityResolver or Handler, where Handler is a combination of the previous three and acts as the default handler. E.g. if Documen-
tHandler is not specified, it will try to use Handler.
EXAMPLE
In this example we use XML::Parser::PerlSAX to parse an XML file and to invoke the PerlSAX callbacks of our SAXT object. The SAXT object
then forwards the callbacks to XML::Checker, which will 'die' if it encounters an error, and to XML::Hqandler::BuildDOM, which will store
the XML in an XML::DOM::Document.
use XML::Parser::PerlSAX;
use XML::Filter::SAXT;
use XML::Handler::BuildDOM;
use XML::Checker;
my $checker = new XML::Checker;
my $builder = new XML::Handler::BuildDOM (KeepCDATA => 1);
my $tee = new XML::Filter::SAXT ( { Handler => $checker },
{ Handler => $builder } );
my $parser = new XML::Parser::PerlSAX (Handler => $tee);
eval
{
# This is how you set the error handler for XML::Checker
local $XML::Checker::FAIL = &my_fail;
my $dom_document = $parser->parsefile ("file.xml");
... your code here ...
};
if ($@)
{
# Either XML::Parser::PerlSAX threw an exception (bad XML)
# or XML::Checker found an error and my_fail died.
... your error handling code here ...
}
# XML::Checker error handler
sub my_fail
{
my $code = shift;
die XML::Checker::error_string ($code, @_)
if $code < 200; # warnings and info messages are >= 200
}
