(first of all, i realize now that -ww is usually all you need -- i can't remember why, but some where i got it in my head that on some systems, you need -www)
I don't have any documentation to back this up, but as i
understand it, this is what happens:
-
If /usr/ucb/ps has no idea where it's output is going
(ie: you are redirecting it, or on a dumb terminal) then it follows the strict
definition in the manpage: 80 chars, unless you use -w in
which case it's 132 chars, unless you use -ww(w) in which case
it's as wide as possible.
- If you are using a non-dumb terminal, and /usr/ucb/ps
can determine your terminal width, then it will use that
width by default. if you use -w (or -ww or -www) it will output as much as possible
you probably aren't really seeing -w truncated to 80 characters when you pipe it -- you're probably seeing it truncated to 132, which is all -w is documented to give 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).
