print "$Robert has canned ${name}'s sorry butt\n";

The apostrophe is the old-style package separator, still supported, so $name's is indeed equivalent to $name::s. By putting the curlies in there, you tell Perl exactly which part of the string to consider part of the variable name, and which part to consider a literal value.

Makeshifts last the longest.

[jdporter]: so that I can use the existing expand unix util. Otherwise, I'll probably use Text::Tabs.
[1nickt]: pryrt I guess I don;t really care if user 42 logs on as 42.0 ... more of an academic question at this point.
[LanX]: jdporter: open PIPE,'-|' ?
[LanX]: oh you want the result line by line?
[jdporter]: ok, LanX, then what?
[jdporter]: It doesn't have to be line by line. Just "my program" "writes" to the external prog and also/then "reads" from it.
LanX open (You are not allowed to open to a command that pipes both in and out, but see IPC::Open2, IPC::Open3, and Bidirectional Communication with Another Process in perlipc for alternatives.)
[jdporter]: IPC::Open2, I guess
[jdporter]: yes, that
