Assuming that I didn't miss a smiley face, the '-M' option
is a way do a "use" on a Module before executing your
program and the '-e' option allows you to specify the program
text directly on the command line.
Quoting from the "perlrun" FAQ:
-m[-]module
-M[-]module
-M[-]'module ...'
-[mM][-]module=arg[,arg]...
-mmodule executes use module (); before executing your program.
-Mmodule executes use module ; before executing your program.
You can use quotes to add extra code after the module name,
e.g., '-Mmodule qw(foo bar)'.
If the first character after the -M or -m is a dash (-) then
the 'use' is replaced with 'no'.
A little builtin syntactic sugar means you can also say
-mmodule=foo,bar or -Mmodule=foo,bar as a shortcut for
'-Mmodule qw(foo bar)'. This avoids the need to use quotes
when importing symbols. The actual code generated by
-Mmodule=foo,bar is use module split(/,/,q{foo,bar}). Note
that the = form removes the distinction between -m and -M.
-e commandline
may be used to enter one line of program. If -e is given,
Perl will not look for a filename in the argument list.
Multiple -e commands may be given to build up a multi-line script.
Make sure to use semicolons where you would in a normal program.
And as Rob (Sisyphus) said, you have to use different quoting
mechanisms under Unix versus Win32 shells. Examples:
> perl -MLWP -e 'print "$LWP::VERSION\n"'
this works under Unix shells as the single quotes suppress
the shell from trying to treat $LWP as an Environment variable
substitution
> perl -MLWP -e "print qq($LWP::VERSION\n)"
this works under the Win32 CMD shell as you can only use
double quotes around a command line argument. The qq()
construct is a alternative Perl way of specifying a
string that allows variable interpolation.
Anyway, hope this helps.

Mike,
First, thanks!
Second, what was my book doing with telling me to enter
perl -MLWP -e 'print "$LWP::VERSION\n" '
from the command line??????????
Jerry
***************************************
It's just the "LWP" module in "libwww-perl".
Try doing this.
use LWP;
print "version=", $LWP::VERSION, "\n";

Subject: Which LWP?
Tutors,
I am to the LWP chapter in Suehring's "Beginning Perl Web Development".
I know I need to use PPM to install LWP, but which one??? Here's what I
tried:
ppm> search LWP

1. LWP-attic [1.00] LWP-attic
2. LWP-Authen-Wsse [0.05] LWP-Authen-Wsse

14. LWP-UserAgent-WithCache [0.03] LWP-UserAgent-WithCache
ppm> install libwww-perl
Note: Package 'libwww-perl' is already installed.
Man, it is great to know a clear answer is on the way. Seriously, this
group is great!
Jerry
P.S. My guess is #12. My second guess is #14. #10?
