(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.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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 How to display code and escape characters are good places to start.
