Hi.
Of the systems on which I tried to use od with a directory, Solaris 10 failed, but (some versions of) IBM AIX, and HP-UX succeeded.
The K & R book was written a long time ago, before Linux was created. I do not know why Linux restricts commands like cat and od from dealing with directories.
The chmod behavior might be explained by the setting of your umask. See man umask for details ... cheers, drl

spreadsheet::parseexcel::simple
Spreadsheet::ParseExcel::Simple(3pm) User Contributed Perl Documentation Spreadsheet::ParseExcel::Simple(3pm)
NAME
Spreadsheet::ParseExcel::Simple - A simple interface to Excel data
SYNOPSIS
my $xls = Spreadsheet::ParseExcel::Simple->read('spreadsheet.xls');
foreach my $sheet ($xls->sheets) {
while ($sheet->has_data) {
my @data = $sheet->next_row;
}
}
DESCRIPTION
This provides an abstraction to the Spreadsheet::ParseExcel module for simple reading of values.
You simply loop over the sheets, and fetch rows to arrays.
For anything more complex, you probably want to use Spreadsheet::ParseExcel directly.
BOOK METHODS
read
my $xls = Spreadsheet::ParseExcel::Simple->read('spreadsheet.xls');
This opens the spreadsheet specified for you. Returns undef if we cannot read the book.
sheets
@sheets = $xls->sheets;
Each spreadsheet can contain one or more worksheets. This fetches them all back. You can then iterate over them, or jump straight to the
one you wish to play with.
book
my $book = $xls->book;
The Spreadsheet::ParseExcel object we are working with. You can use this if you need to manipulate it in ways that this interface doesn't
allow.
SHEET METHODS
These methods can be called on each sheet returned from $xls->sheets:
has_data
if ($sheet->has_data) { ... }
This lets us know if there are more rows in this sheet that we haven't read yet. This allows us to differentiate between an empty row, and
the end of the sheet.
next_row
my @data = $sheet->next_row;
Fetch the next row of data back.
sheet
my $obj = $sheet->sheet;
The underlying Spreadsheet::ParseExcel object for the worksheet. You can use this if you need to manipulate it in ways that this interface
doesn't allow (e.g. asking it for the sheet's name).
