Re: exec status with no command is 0 but no redirection

[fpo]

Correct, my idea was to redirect the output of the whole script. The 
example used a sample 'echo' but it could instead produce dynamically 
some ISO-8859 encoded strings, due to some external constraints (ie. 
database). I thought it could be an easy way to do that in a single 
script. And your last comment makes it well. Thanks.
