Dear All
I have a tab delimited dataset "RawFile":
abcd 123 456 defg
cdefg 23 as
345 235
xsd swe
And I want to change all missing values to "Missing". So I wrote the following codes:
#!/usr/bin/perl
use warnings;
use strict;
open(my $outfile,">","UpdatedFile") || die " \n";
open (my $infile,"<","RawFile") or die "Cannot open: $!\n";
while(<$infile>){
chomp;
my @fieldsvar =split(/\t/);
foreach (@fieldsvar) {
if ($_ eq ""){$_="Missing"}
}
print $outfile "@fieldsvar\n";
};
The code works ok, except that I have to create a new file "UpdatedFile"; can anyone suggest some method so that the code can be re-written which can do a in-place update of the "RawFile"?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
