Attempting to use SFTP between Windows and Linux box
I have a couple of processes that run one on a production box and another on a test box. The production box script checks that a particular file is never more than 40 minutes old while on the test box, this checks that the actual polling processes ( in this case three pollers ) also are never more that 40 mminutes old. Each poller does it's work and then the last action it does is open a file as output and closes. This has worked very over the last few years, but now with the movement to Linux, they want secure checking and uncertain what I am doing wrong ( or even right for that matter ). I am running under XP SP 2, AS 5.8.8(build 824). I am attempting login via SFTP to pull up the file so I can check it's stats. What I get in my output log is: IT2ua815132X: Reading configuration data C:/Documents and Settings/drw6386/.ssh/config IT2ua815132X: Reading configuration data /etc/ssh_config IT2ua815132X: Connecting to dhprltest.hro.freight.fedex.com, port 22.

Obviously I am trying to do this in batch/monitoring mode ( no interaction ). Any insights or thoughts on how one approach this would be greatly appreciated?

If the number of files is fewer than a two hundred this is fine, but
if it is more then you really want to use a min routine rather than
sort to find the oldest file:
#FIXME: if two files are the oldest, we can't predict which one will be deleted
my $oldest_name;
my $oldest_date = 0;
for my $file () {
if ($oldest_date >= (stat $file)[8]) {
# _ is used here to get the cached info
# from the last stat call
$oldest_date = (stat _)[8]; last stat call
$oldest_name = $file;
}
}
die "no files found" unless defined $oldest_name;
print "the oldest file is $oldest_name\n";

Try "%15s" instead; "%15u" seems to cut-off the numbers.

use warnings;
my $n = 1;
for my $i ( 1 .. 15 ){

Adding Very Large Numbers and Display
Hello I have a perl script that is working fine. The script involves creating an array of numbers. The values of these numbers in the is quite large (12 integer digits or more). I can easily display the numbers with a simple print statement. I want to display the contents with one element per line and format it so that it lines up vertically. This is where I am running into issues. I tried to use a sprintf statement with a format of "%15u" so that I did not get a negative number. However the value displayed is much smaller than what the actual value. What is the best way to fix this display issue?

Spreadsheet::ParseExcel allows you to read an existing file and Spreadsheet::WriteExcel allows you yo write a new file. The only way I know of to create the illusion of an arbitrary edit is to use both together to copy the data from the old file to a new file making changes as needed, unlink'ing the old file, and rename'ing the new file to the old file's name. Well, that isn't 100% true; if you are on a Windows machine that has Excel installed you can use Win32::OLE to make Excel make your changes for you. -- Chas.

need help with SpreadSheet::Parse perl module
Hi,
Following is the piece of code
my $parser =
Spreadsheet::ParseExcel::Workbook->Parse('tablle2sheet.xls');;
#parseexcel method that would open the file for writing
my $sheet= $parser->Worksheet($Worksheet);
my $rw=$sheet->{MaxRow}+1;
print "rowcount:$rw\n";
something like-sheet3->write(0,0,'xyz'); doesn't work here
in the above code I get the max row count of my sheet by reading it using
the Spreadsheet::ParseExcel::Workbook module of cpan.
then I want to open the same tablle2sheet.xls for writing.but currently I am
not able to find any module which allows me to do that.
Can someone help/

Perl Call from Java dumps core while making a FTP connection
I need help with an issue with executing a perl program from java. I have a perl script that does a FTP. The perl program works well when I run it from command line or on a cron job. The same command I am also running from a Java program, it used to run fine on Solaris 8 and Perl 5.8.0. When we moved to Solaris 10 now, perl version being the same but this java to perl call results in a core dump. We did an initial core read, it points to an error like "Can't find LocalCfg.pm in the path @INC". Is this a right error message or does it point to some perl module not being installed correctly in the new environment. I do not even see any LocalCfg as a perl module in our install tree.
