then
echo "blah"

Whenever I run it, each token of lpinfo is being interpreted as a command and I get errors such as:

ipc::run::debug
IPC::Run::Debug(3) User Contributed Perl Documentation IPC::Run::Debug(3)NAME
IPC::Run::Debug - debugging routines for IPC::Run
SYNOPSIS
##
## Environment variable usage
##
## To force debugging off and shave a bit of CPU and memory
## by compile-time optimizing away all debugging code in IPC::Run
## (debug => ...) options to IPC::Run will be ignored.
export IPCRUNDEBUG=none
## To force debugging on (levels are from 0..10)
export IPCRUNDEBUG=basic
## Leave unset or set to "" to compile in debugging support and
## allow runtime control of it using the debug option.
DESCRIPTION
Controls IPC::Run debugging. Debugging levels are now set by using words, but the numbers shown are still supported for backwards
compatibility:
0 none disabled (special, see below)
1 basic what's running
2 data what's being sent/recieved
3 details what's going on in more detail
4 gory way too much detail for most uses
10 all use this when submitting bug reports
noopts optimizations forbidden due to inherited STDIN
The "none" level is special when the environment variable IPCRUNDEBUG is set to this the first time IPC::Run::Debug is loaded: it prevents
the debugging code from being compiled in to the remaining IPC::Run modules, saving a bit of cpu.
To do this in a script, here's a way that allows it to be overridden:
BEGIN {
unless ( defined $ENV{IPCRUNDEBUG} ) {
eval 'local $ENV{IPCRUNDEBUG} = "none"; require IPC::Run::Debug"'
or die $@;
}
}
This should force IPC::Run to not be debuggable unless somebody sets the IPCRUNDEBUG flag; modify this formula to grep @ARGV if need be:
BEGIN {
unless ( grep /^--debug/, @ARGV ) {
eval 'local $ENV{IPCRUNDEBUG} = "none"; require IPC::Run::Debug"'
or die $@;
}
Both of those are untested.
