Dear monks,
every time I use a perl-onliner with -ane and @F, I wonder why I can't access a single column of the input file with $F[6] (which contains undef) but have to use @F[6] and will get warned if I enable warnings about like the following way:
Scalar value @F[6] better written as $F[6] at -e line 1.
An example code may be:
perl -0012 -ane "print join(' => ',@F[8,6]),qq~\n~ if @F[6]=~/cmd\.exe
+/" access.csv;
For input file, I used an apache access-log where the spaces were replaced by a tab as separator.
Do you know the reason for this strange behaviour?
Best regards,
perl -e "s>>*F>e=>y)\*martinF)stronat)=>print,print v8.8.8.32.32.32"

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).
