When a script is executed STDOUT and/or STDERR may
be redirected
as follows:
perl script.pl > log.txt or
perl script.pl 2> log.txt or
perl script.pl | taker.pl etc,
and all the other variations.
My question is this:
Can I find out
1) whether redirection has been specified?
2) if it has, which handle - STDOUT and/or
STDERR - has been redirected?
3) and also, if redirected to a file or another
script, the name of
the file or script?
*any* clues would be most appreciated.
