I think I finally have a clean solution. After much reading and asking around in the office someone helped me with this snippet, assuming TAIL is the file handle you're doing the tail -f on. The answer is to simply redo the failed operation which previous responses had suggested. So if anyone is interested this is what I've settled on and particularly like it because it's short and straightforward:

while (1)
{
  while(1)
  {
    my $line = <TAIL>;
    if (!defined($line))
    {
      redo    if $! eq 'Interrupted system call';
      last;
    }

    print $line;
  }
  printf "Fell through...\n";
}

• 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).
