Hi Monks,
I am having a file named one.txt,the contents are like,
This file is having data
It is used for authentication
Authentication number is 9
When I am running my script I get the new authentication no by @ARGV.If my new authenticaton is not equal to the authentication no found in the one.txt file,the new authentication number should be replaced inthe one.txt file.For this simple work I am using lot of lines.It looks bad for me.Let me know some other professional code to reduce my lines monks.The code is given below,
perl auth.pl 9
$argact = $ARGV[0];
open input,"one.txt";
open newfile,">output";
while(<input>){
if($_ =~ /^Authentication\s+number\s+is/){
@array = split(" ",$_);
$fileid = (split(" ",$_))[3];
if($fileid ne $argact){
$changeflag = 1;
pop(@array);
push(@array,$argact);
$newline = join(" ",@array);
print newfile "$newline\n";
}else{
print newfile "$_";
}
}else{
print newfile "$_";
}
}
Thanks and Regards,
madtoperl.

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).
