Hi,
 
I try to log all the outputs of a sh function [ my_func | tee
my_logfile ].

my_func is defined and called from my_script and modifies variables
defined in my_script.

The problem with 'my_func | tee my_logfile' is that it creates a
sub-shell where my_func has its own copy of my_script's variables.
When my_func returns, the subshell exits and everything is logged fine
BUT the modified variables are, of course, not taken into account.

How can I log everything from my_func AND be able to modify
my_script's variables ?

Gael.
