If I understand your question correctly, you want to run a script which calls multiple commands all of which are redirected to a single logfile. You can redirect the STDOUT and STDERR upon entry into the calling script. All subsequent commands will inherit the redirection from the calling script.

Code:
#!/bin/ksh

    exec 1>>/var/log/script.log 2>&1

    command1
    command2
    command3

One short-coming would be that you would not necessarily know which command generated which errors unless they're sufficiently different. By adding an echo before each command, you would know in which command you were when messages were generated.
Code:
#!/bin/ksh

    exec 1>>/var/log/script.log 2>&1

    echo "$0 (I) Starting command1"
    command1
    echo "$0 (I) Starting command2"
    command2
    echo "$0 (I) Starting command3"
    command3

Upon reflection, I don't think I'm grasping the problem. Could you please provide a little more detail? Thanks.

Appender::Screen(3pm)					User Contributed Perl Documentation				     Appender::Screen(3pm)

NAME
Log::Log4perl::Appender::Screen - Log to STDOUT/STDERR SYNOPSIS
use Log::Log4perl::Appender::Screen; my $app = Log::Log4perl::Appender::Screen->new( stderr => 0, utf8 => 1, ); $file->log(message => "Log me "); DESCRIPTION
This is a simple appender for writing to STDOUT or STDERR. The constructor "new()" take an optional parameter "stderr", if set to a true value, the appender will log to STDERR. The default setting for "stderr" is 1, so messages will be logged to STDERR by default. If "stderr" is set to a false value, it will log to STDOUT (or, more accurately, whichever file handle is selected via "select()", STDOUT by default). Design and implementation of this module has been greatly inspired by Dave Rolsky's "Log::Dispatch" appender framework. To enable printing wide utf8 characters, set the utf8 option to a true value: my $app = Log::Log4perl::Appender::Screen->new( stderr => 1, utf8 => 1, ); This will issue the necessary binmode command to the selected output channel (stderr/stdout).
