not a dbi question

[Xiaoxia Dong]

This is NOT a DBI question, rather it is a perl question. Maybe somebody
can help me.

I use the find <directory> -type d -print >aa.txt
then open aa.txt

$dir = <FD>
when use this to check to see if it is directory, it always return
undef.

return undef unless -d $dir;
i print out $dir, which is correct if type in command line

any idea?
