Re^4: Data validation and blank spaces in tab formatted csv file

Thanks, Does Perl distinguish between white space and null. For example, this field contains no data but white space:

chomp($pending_move_out_dt);
$pending_move_out_dt =~ s/\s//g;
[download]

I want to remove all white spaces for that field so that field appear as null (undefined) if there is no data. Any way to do this.
