Hi,
Just for fun, I'd like to use perl instead of sed on the following line:
echo $HOME/Mail/* |sed 's/sent-mail //
So far, I've tried various things that leave me with no output or wrong output. E.g:
echo $HOME/Mail/* | perl -e 'while (<STDIN>=~s/sent-mail//) { print "
+$_"}'
I've had a look at the Capturing input from pipe? node,
but I'm still clueless. I've also used the s2p (sed2perl) program, but the output seems far from succint. I thought perl would be able to do the same task in as short a line as the sed command. Can it?
I'm very much a perl novice (initiate even), and would really appretiate your help.
Thank You.

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).
