I'm sorry, but I don't fully understand what you're trying to do. It would be best if you could explain more, with a runnable SSCCE, example input and expected output. Otherwise I am left guessing, for example, based on your code it's not clear to me what @abc contains. Is this a list of commands you want to run, or is it the output of another command? If it's the latter, note that the other monks have already shown you how to handle that, like Discipulus's post here. How are you running the external command, from the command line with the input piped to the Perl script like in the gnomon example (which my code handles), or do you want to invoke the external command from inside the Perl script? If it's the latter, note that my code might not be the best way to do this, and you might need to switch to a module like IPC::Run.
Is this possible to make it a subroutine and call it by default in all STDOUT?
Are you asking how you can modify your own Perl script's output to prefix it with the current time (like a log), instead of another program's output?

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).
