 Posix::isatty (in words: is_a_tty) could be worth a look. It returns true, if the filehandle is associated with a terminal.

    Isatty won't return true on a pipe or a named pipe (fifo) or a socket, so it's not what I want. By the way, isn't the -t filetest operator the same as isatty?

[abner]: yes. i am familiar with mysql but ignorant about how to get around the fact that placeholders can only represent single scalar values.
[abner]: my $sth = $dbh->prepare(' SELECT * FROM charge WHERE cpt = ?') or die "Couldn't prepare statement: " . $dbh->errstr;
[abner]: what if i want SELECT * FROM charge WHERE col1 = x and col2 = y?
[atcroft]: abner: So you are wanting to do something like my $sth = $dbh->prepare(' SELECT * FROM charge WHERE col1 = ? and col2 = ?;'); $sth->execute(' asdf', 'asdw');?
[atcroft]: (Full disclosure: I may have the idea right but small typographical errors, so please test any code I suggest. :) )
