Run3 apparently doesn't do concurrency. IPC:Run can be made to do what you want. This works:

#!/usr/bin/perl # timestamp.pl while(time - $^T<10){ select undef,undef,undef, 0.1; if ( rand()<0.5) { print STDERR time(), " warn\n"; } else { print time(), " info\n"; } } print "end\n"; __END__ use IPC::Run qw ( start pump finish timeout ); my $in; my $out; my @cmd = qw( perl timestamp.pl); ## Build the harness, open all pipes, and launch the subprocesses my $h = start \@cmd, \$in, \$out, \$out ; $in = "" ; ## Now do I/O. start() does no I/O. pump $h while length $in ; ## Wait for all input to go ## Now do some more I/O. while (1){ pump $h until $out =~ s/(.+)\n$//gm ; last if ("end" eq $1); print time, " : $1\n"; } ## Clean up finish $h or die "cat returned $?" ; __END__ 1215226647 : 1215226647 info 1215226647 : 1215226647 info 1215226647 : 1215226647 warn 1215226647 : 1215226647 info 1215226647 : 1215226647 warn 1215226647 : 1215226647 warn 1215226647 : 1215226647 info 1215226647 : 1215226647 info 1215226647 : 1215226647 info 1215226648 : 1215226648 warn

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.
