( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I am looking to capture the output of a log file which is being generated by another process into a new text file,initially I just want to be able to see the errors I am getting, but eventually I will want to be able to parse the file as it is being created for specific error messages. how do I do this will something like this work? taken from example in synopsis from file tail. $name? shouldn't this be defined somewhere?
use File::Tail; use win32::OLE qw(in); $file=File::Tail->new("E:\\mibor_timingtest\\mibor\\output.txt"); while (defined($line=$file->read)) { print "$line"; } use File::Tail; $file=File::Tail->new(name=>$name, maxinterval=>300, adjustafter=>7) +; while (defined($line=$file->read)) { open(OUT ">>", "c:\\test.txt"); print(OUT "$line"); } sub_do_something{ use win32::OLE qw(in); $search="stuff2searchfor"; open(OUT, "c:\\test.txt"); my @array=<INFO>; close (INFO); foreach $line(@array){ if ($line =~ /$search/) { print "found $line"; sendmail_call_here..to send alert }

  • 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.
