People talk about one-liners, but it's usually just to say that someone's usefull little utility could be collapsed into an unreadable glumph of line noise .... wait, that's the deinition of Perl, isn't it?

But what one-liners do people actually use? I regularly alter Autosys meta-scripts to run a new version of a set of scripts, or to target a new database, or to run on a new host, using perl as a super-sed:

co -l *np40* perl -pi -e"m/host:/ && s/paias167/pa167c1n1/" ci -u -m'move scripts to new hosts' *np40*

Title:
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.
