Zentara is right about what you need to do, but a fuller explanation
of the solution would have been:
Net::SFTP is throwing an exception when it cannot make the
connection. If the exception is not caught, it will cause your
program to exit. The way you catch exceptions in Perl is to wrap the

Executive summary: It looks like, no matter what context foo() is called
in, its arguments are always evaluated in list context. Is this correct?
I had always understood that:

Hi Matthew,
First of all, subtracting scalars is perfectly valid, so the actual error
must be something else. Here are three things you should check.
1) First, you don't have a semicolon at the end of that line.
2) Second, if you are operating under 'use strict', you will need to
predeclare

Any of the following should work for you:
if ( -e $dirpath -d $dirpath ) { ...stuff...}
if ( -e $dirpath -d _ ) { ...stuff...}
if ( -d $dirpath ) { ...stuff...}
You can always substitute $dirpath for a literal string path in the above
as well...e.g.:
if ( -d '/usr/bin/home' ) { ... stuff
In practical daily use, use(); is preferred as since it compiles the
module as soon as it sees 'use Foo::Bar;' before moving on, this will
catch errors and scope conflicts far sooner than if you use require();
There aren't many good reasons to use require, at least I

Yep,
FYI, Tyler, the reason that this will do what you want is because you're

This creates a list of two elements and assigns it to the hash named

The CPAN module (CPAN.pm) comes with the basic distro of Perl, so you

CPAN. At your command line, you type:
