Two points to remember:
- 1. I shouldn't trust so easily in what others say.
- 2. I should frequently practice with my monitor some oneliners with the examples that I learn...
Why? This is what I have just tryed...
perl -e"$old='abc';$old = tr/a/z/g;print \"$old \n\";"
Bareword found where operator expected at -e line 1, near "tr/a/z/g"
syntax error at -e line 1, near "tr/a/z/g"
Execution of -e aborted due to compilation errors.
There is no tr///g since every replacement is done on all the characters. So the /g would always be unnecesary. Just try it!

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).

Want more info? How to link or
or How to display code and escape characters
are good places to start.
