Re^4: Best practice ipc and Log::Log4perl

Thanks for your solution IPC::Run is probably the best way to go. If you set $|++ in timestamp.pl we have it.

perl -MIPC::Run=run -e '
run( [ "perl", "timestamp.pl" ],
       "1>", sub { print "out " . time() . " " , @_ },
       "2>", sub { print "err ". time() . " " , @_} )
'

Hi, Excuse me for posting to this old threat, but I run in a similar situation where IPC::Run and Log::Log4perl were combined. I must remark that the title is actually misleading because no one has mentioned log4perl in his/her solution. Thus I will: `use IPC::Run qw(run new_chunker); # snip-snap-snip # ... my @cmd = qw(find /usr/bin -type f); run(\@cmd, "1>", new_chunker, \&logSdtout, "2>", new_chunker, \&logSdt +err); sub logSdtout { $logger->info(@_); } sub logSdterr { $logger->error(@_); }` [download] edit: you need to pass the filter "new_chunker" to IPC::Run to break the output from your external program into newlines. Otherwise you will run into strange exceptions (undefined values) causing IPC::Run to fail. Cheers, Daniel	[reply] [d/l]

use IPC::Run qw(run new_chunker);
# snip-snap-snip
# ...

my @cmd = qw(find /usr/bin -type f);

run(\@cmd, "1>", new_chunker, \&logSdtout, "2>", new_chunker, \&logSdt
+err);

sub logSdtout
{
 $logger->info(@_);
}

sub logSdterr
{
  $logger->error(@_);
}
