But you also want to assign to a variable, correct?

Code:
a=`( expr $i + $j | tee -a $log_file ) 2>> $log_file`

Now, STDOUT goes to the $log_file, and is stored in the variable. STDERR is appended to the logfile.

Cheers

Net::Server::Log::Log::Log4perl(3)			User Contributed Perl Documentation			Net::Server::Log::Log::Log4perl(3)

NAME
Net::Server::Log::Log::Log4perl - log via Log4perl SYNOPSIS
use base qw(Net::Server::PreFork); __PACKAGE__->run( log_file => 'Log::Log4perl', log4perl_conf => '/path/to/my/log4perl.conf', log4perl_logger => 'myapp', ); DESCRIPTION
This module provides Log::Log4perl style logging to the Net::Server system. CONFIGURATION
log_file To begin using Log::Log4perl logging, simply set the Net::Server log_file configuration parameter to "Log::Log4perl". If the magic name "Log::Log4perl" is used, all logging will be directed to the Log4perl system. If used, the "log4perl_conf", "log4perl_poll", "log4perl_logger" may also be defined. log4perl_conf Only available if "log_file" is equal to "Log::Log4perl". This is the filename of the log4perl configuration file - see Log::Log4perl. If this is not set, will die on startup. If the file is not readable, will die. log4perl_poll If set to a value, will initialise with Log::Log4perl::init_and_watch with this polling value. This can also be the string "HUP" to re- read the log4perl_conf when a HUP signal is received. If set to 0, no polling is done. See Log::Log4perl for more details. log4perl_logger This is the facility name. Defaults to "Net::Server". DEFAULT ARGUMENTS FOR Net::Server The following arguments are available in the default "Net::Server" or "Net::Server::Single" modules. (Other personalities may use additional parameters and may optionally not use parameters from the base class.) Key Value Default ## log4perl parameters (if log_file eq Log::Log4perl) log4perl_conf "filename" will die if not set log4perl_poll number or HUP 0 (no polling) log4perl_logger "name" "Net::Server" METHODS
"initialize" This method is called during the initilize_logging method of Net::Server. It returns a single code ref that will be stored under the log_function property of the Net::Server object. That code ref takes log_level and message as arguments and calls the initialized log4perl system. LICENCE
