For the most part, I don't use one liners anymore; they typically cost me more time than they save.

For me, there are usually only two cases:

1) It's something I've done before -- in which case, it's nice to have it in a script, so that I can just type the name of the script, and worry less about typos or forgetting a step. Plus I can check the perldoc to find out what it does (when I write a script, I have a stronger incentive to write documentation than if I'm pulling a line out a command history).

2) It's something I've never done before -- in which case, it's nice to put it into a script, so that when I screw up the typing for the 11th time, I don't have to retype the whole thing. Sure, a decent command line can substitute, but it's still nicer to have a copy with the final version of what I've done, just in case I wonder in two weeks "how did I do that?", or worse yet, "What *exactly* did I *do*?".

That's just my experience; I used to like one liners, but in the longer term, I found the "time savings" by using them to be rather deceptive; I save more time in the long term by writing a clean script in the first place.

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 or How to display code and escape characters are good places to start.
