RE: Formatting integer input: use the sprintf() in perlfunc - Perl builtin functions
whenever you need to do any special formatting like this, especially numbers, use the sprintf() in perlfunc - Perl builtin functions for your case, try this: print sprintf(%05.02f\n, 4.5 ); 04.50 Why not just use 'printf()' for this? Makes it somewhat less confusing while doing essentially the same thing in the background: printf %05.02f\n, 4.5; The difference lies in if the '$\' ($OUTPUT_RECORD_SEPERATOR) is set when you use the first example it will add an extra newline that you probably would not intend (given the \n in the format). printf() will ignore the value of $\ and format only according to your format argument. Just a suggestion.

z:CGI.pm is great but it's an overkill for just printing HTTP Content-Type
z:header.
that is true, however i cut the code out of a script i had handy. the
params are passed in as such:
/cgi-bin/mime.cgi?filename=whatevermime_type=application%02Fpdf
so the full file looked something like this:
use CGI;
my $cgi = new CGI;
my $filename = $cgi-param('filename');
my $mime_type = $cgi-param('mime_type');
print $cgi-header($mime_type);
open OUT, $filename;
my $buffer;
while (my $read = read(OUT, $buffer, 4096)) {
print $buffer;
}
close OUT;

Net::FTP or similar
Hello, Has anyone used Net::FTP to create a browser based FTP client? (I assume that's one use for it) I have a client that needs to let their clients transfer files to and from their server. Some of the files may be big (30-40MB) and using a regular FTP client isn't an option, unfortunately. I'm interested to hear peoples experience or suggestions.

Installing/Uninstalling CPAN modules
This may be the wrong forum to ask this... How do I uninstall a module downloaded from CPAN? Specifically, I cannot get the DBD::MySQL driver to install under OS X. It refuses to find the mysql_config file, and when I run Makefile again with the -L and -I switches it won't work after install. I am running the Complete MySQL distribution which has worked before, but since this installs into /usr/Library and not /usr/local, I am wondering if the module ignores symlinks to /usr/local. Hence I want to pull everything out and reload the MySQL AB distribution and try again. A quick search shows DBD in dozens of places, in perl/ in DBI/ in mySQL/ etc etc, which ones do I trash?

I have used CGI to allow someone to upload files, and I have used Net::FTP to transfer files between servers, but I am not sure I know what you mean by a browser based FTP client. Presumably you have a web server at your disposal which can take uploads, but then I am at a loss as to why you need FTP? If you mean to act as a proxy, so the file gets transferred to the web server, and then routed from there somewhere else, then basically you have a proxy and the underlying technology could be anything that allows file transfers, aka SSH, NFS, FTP, etc. But at that point the technologies are in effect not linked, so you would be better off dividing the tasks. In other words, have a CGI that just stores a file locally, then have another process watch/poll/scheduled to check for new uploads, in the event one exists, then do whatever it is you do when a new file is present, if that is FTP so be it. The one problem I can definitely see you running into, especially based on the file size you mentioned, is timeouts both on the server and client side. There is also another HTTP protocol request type specifically for this, but I can't remember what it is right now (because it is almost never used for anything...) that essentially just allows a file to be stored to the server, but yikes Unless you mean something along the lines of Mozilla and XPI? But then you are talking about Net::FTP installed on the client side... http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

You may have better luck in the [EMAIL PROTECTED] list since OS X likes to do all kinds of weird things with its Perl, and with regards to DBI/DBD in [EMAIL PROTECTED] Typically removing a Perl module is not as easy as installing them, removing the associated files is only one step...
