need syntax help

[ToddAndMargo]

Hi All,

I was over at
http://search.cpan.org/~fkolodny/Net-Rexec-0.12/Rexec.pm
looking at the rexec example. (I have rexec working on a server I want
to read the tape drive status off of.)

Okay, I know, just try it an see, but I will not be out to the
location for a while and I was hoping someone would put
me out of my ignorance

Syntax question: how do I enter "mt -f /dev/st0 status; grep -i
online"
into the "command" field below? Do I put quotes around it?
How do I separate my command from the "userid" and
"password"? I am concerned that the line below will
confuse "-f" for the userid, etc..

use Net::Rexec 'rexec';
($rc, @output) = rexec(host, command, [userid, [password]]);

Many thanks,
--T

Um, it already has quotes around it as you show it above. That should
do nicely, except you probably don't want the newline.

How do I separate my command from the "userid" and
"password"? I am concerned that the line below will
confuse "-f" for the userid, etc..

Um, with the commas shown. You're making it too hard. I assume the
arguments are all supposed to be strings, so each argument should be an
expression which evaluates to a string. Specifically they should not be
barewords as shown in the description below. An example might be:
($rc,@output)=rexec('my_host',
'mt -f /dev/st0 status; grep -i online',
'my_userID','my_password');
or, if those things were all defined as variables:
($rc,@output)=rexec($host,$command,$userID,$pw);

use Net::Rexec 'rexec';
($rc, @output) = rexec(host, command, [userid, [password]]); ....

Mind if I piggyback a request here? (pls cc email)

Two years ago, someone wrote me this PERL script on a piece of
scrap paper and I had difficulty figuring out some of the writting.

esp: is that x or *???

perl -pe 'if ($.%4==2){$_.="-" x 37} elseif {$.%4==0) {$_.="=" x 37} $_.="\n"'
< %1 >%1


Then I want to make it double spaced.
Every second blank (fourth of the total) line should then
be replace with a line of 37 "-" characters..
and then every second dashed line (every fourth blank aka every eighth
actual) should be replace wit a line of 37 "=" characters..

This script does not have fold/justify at col 37,
but it would be nice if it did.

Much obliged.

What happened when you tried each? Did one "work" while the other
didn't?

Do you know the difference between the two operators? You can look
them up in
perldoc perlop

perl -pe 'if ($.%4==2){$_.="-" x 37} elseif {$.%4==0) {$_.="=" x 37} $_.="\n"'
< %1 >%1

What have you tried so far, and how did it not work the way you wanted?

no.


Two years ago, someone wrote me this PERL script

It is not a Perl, nor perl, nor PERL script...

esp: is that x or *???

The x operator is described in:

perldoc perlop

perl -pe 'if ($.%4==2){$_.="-" x 37} elseif {$.%4==0) {$_.="=" x 37} $_.="\n"'

^^^^^^ ^
^^^^^^ ^

Perl does not have an "elseif" keyword. It does have an "elsif"
keyword though.

The condition must be in properly balanced parenthesis.

You are a spectacular asshole.

Perl. Not PERL.

Then why do *you* spell it PERL here?

Dumbshit.

now that you have shown yourself to be a useless jerk, please go learn
python and bother them. you have no reason to be here.

Is junior still trying to post here? I can't decide if he's as stupid
as his writing or if he's writing to the best of his abilities. Either
way, he's the most boring and dimwitted kind of troll...

Methinks if you're going to call other people dumbshits, you should
learn the correct spelling of "methinks", dumbshit.

that is either a font style that

I don't think someone who hasn't found SHIFT on his keyboard is in any
position to comment on fonts or capitalization.

Quick quiz for you, Urine Gnatman. Why would an asshole who goes about
on USENET being an asshole by correcting others' capitalization of
"Perl" spell it with ALL CAPS at the top of his index page (whatever
the excuse)? Because he's a dumbshit, that's why.

Are you still posting OT posts here after calling those who do
"morons", moron?

What does your post have to do with the language called Perl, Garrish?
If nothing, what exempts you from posting on topic here?

oh, insulting me with the 'urine' variation. that is so original. please
patent this insult and sue all the others who have babbled it before.

anyhow, this is a perl newsgroup and as you have nothing to say about
perl you should leave now. go or i will tell your mother on you and you
will go to bed without your supper or amiga to play with.

now i await your further childish responses which have nothing to do
with perl. tick. tick. tick.

because he actually helps people with perl here. you do not. simple
binary test but that is beyond your skill level it seems. now go away
before your hurt yourself with those scissors.

Beartiger, why am I listening to you troll and abuse people? Oh wait,
I'm not.

And of course you didn't respond, like a dog to Pavlov's bell, to
someone you consider a "troll". Oh wait, you just did--proving you're
a moron who just fell hook, line, and sinker for my "troll".

Goodbye.

I'll believe it when I see it.

Gee, what happened to Gnatman's misspelling? Hmm, seems to have
mysteriously gone missing. I don't suppose he deleted it because it
was just a little bit embarrassing, eh? Naw. Why would he do that?

Heh heh.

On an asshole scale of 1 to 8, urinate.

Make me. By the way, you can talk about others posting off topic,
because this post of your is sooooo relevant to Perl. Why don't you go
tell someone to use strict or warnings for the billionth time? Why
don't you tell someone to consult perldoc? That's a really fabulous
"contribution" to the Perl community.

go or i will tell your mother on you and you
will go to bed without your supper or amiga to play with.

now i await your further childish responses which have nothing to do

Right, and you'll go right on responding to someone you consider
"childish", while criticizing him for posting off topic while you
continue to do it yourself. Kook.

What does your response have to do with Perl? Or didn't you think
about that before you decided to chide me for posting off topic?

If it has nothing to do with Perl, what exempts you from posting on
topic?

How does his or your off topic posts help people with the language you
don't even know how to spell properly?

Go ahead. Tell us, and burn up yet more bandwidth on this ng with your
off-topic posts.

by virtue of my trying to get you to leave. but you won't. have fun. we
have outlasted much worse trolls than you. you might as well leave now
because you will become bored trolling here.

A cunning strategy: to get someone you consider a "troll" to leave by
.... replying over and over and over to him! You is reeil smaht.

BURRRRRRRP.

Did you know your first name may be changed to the word urine by the
addition of a mere two letters?

You may not know that all-uppercase letters are an acceptable way to
capitalize headings and titles, at least in the USA.
