( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Monks, I am reading a file looking for a specific flagged line. Sample 1 will loop through the entire file never activating the IF() statement. I fixed with sample 2 which stops reading the file at line 4 "testpoint\n". I do not understand why sample 1 doesn't work. I tried several variations including using chomp() . Am I missing something simple like a white space char?
sample 1: while(<FILE>) { if($_ eq "testpoint\n") { last; } } sample 2: while(<FILE>) { if(/testpoint/) { last; } } File contents being read: <begin file> This is a test file data at the front of file more test data testpoint data after the test Last line <end of file>

*note: fixed typo eg => eq happened while simplifying example
also fixed the ? => " happened when cutting a pasting from open office

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.
