Examples are likely the best and fastest way to get a handle on something

UPDATE: RE: get list from database, email list
Update:
I think I may be closer than I thought!
In the original code, I *thought* I was
bringing back the entire select output.
I *believe* I was only bringing in one row.
I am trying to recreate it by testing from
another table. It brings the first row; but
now, the 'fetchrow' part of it *seems* to be working,
but it's only 'fetching ONE row'...
How do I bring back an entire array / list from the
select statement I just made?

get list from database, email list
Hi again:
This is my first attempt at trying to pull info from a
database ... but this is my goal:
A few days ago, I was having problems emailing a list of
users ('documentation about perl / email' ... thanks to
Brett and Jenda for the pointers) and I got to thinking,
"Why not go directly to the database, get the list of users
and append \@domain.com at the end and send the message on
it's way?"
In my current script, however, I'm trying to figure out how
to email myself the result of a select statement from a database.
I think I'm shooting myself with a water pistol repeatedly.
[code]
#!/usr/bin/perl
# Attempting to edit this so that email can be
# set to user community (from users table) without
# needing to get a list of users in a text file
# and THEN emailing them
# created 14 Dec 01 -X
use CGI qw(:standard);
use Pg;
require "/var/www/hminclude.pl";
$conn=dbOpen("dbname=database");
# hopefully, this get my column of email addresses
$result=doquery('Email Community',"
SELECT email
FROM users
WHEREemail ~* '[a-z]'
ORDER BY upper(email) ");
# set the date
open DATE, "date |";
$date=;
chop $date;
# should be the address of sender and users
$addr='[EMAIL PROTECTED]';
$users=$result;
#$message=param('message');
$boundary='!*@&#^$% Apache web server MIME boundary %$^#&@*!';
open MAIL, "|/usr/lib/sendmail -oi -t -odq "
|| print "no sendmail\n";
print MAIL <
To: $addr
Date: $date
Subject: Apache mailing list request
Mime-Version: 1.0
Content-type: multipart/mixed;
Boundary="$boundary"
Content-Disposition: inline
--$boundary
ontent-type: text/html; charset=us-ascii
Content-Disposition: inline
This is a list or message that would go to the list
of users if we need to send them something.
For your reference, the query executed is shown below:
$users
EOF
;
close(MAIL) || print "can't close mail\n";
print "mail has been sent\n";
__END__
[/code]
The SQL part works. The mail part works. But I'm not pulling (or trapping)
the data that I want. The only thing I get is
a message that says:
[message]
This is a list or message that would go to the list
of users if we need to send them something.
For your reference, the query executed is shown below:
`PG_results=SCALAR(0x81a82a0)`
[/message]
How does that work? I don't understand how to query and have
perl KEEP the data in some variable for me to print (or use) later.
I'm not even sure how to check to see if I'm even connecting properly.
By the way, I'm sorta looking at examples and attempting to 'learn
as I go' ... yeah, I know. I need a better method of learning ...

Lance,
Yes, you can do this. Here's one way:
my $x = 7;
if ( $x > 5 or $foo eq 'bar' ) {
# do this
} else {
# do the other thing
};

RE: Question about using an IF statement in searching a sub string
It's not clear from your post if you should expect $line to have a value
when it encounters the if statement. You might find a 'print "<$line>\n";'
right before the if statement really informative. The angle brackets are
just in case $line is undef and you don't have warnings turned on.

If so can I get an example? You probably want LWP::Simple; you can find it on CPAN.

You did not make %_Globals local to the MakeEth subroutine, so it is be
default global. If you weren't seeing the results of the assignment it's
because you were using "eq" instead of "=". "eq" is a comparison operator,
"=" is the assignment operator.

What do you mean by unlink? Do you mean the variables are removed from memory? Provided you're running this as a standalone program, and not embedded in something (say, mod_perl), then the variables, and any other memory the program is using, will be reclaimed by the system when the program exits.

This is likely an issue with Win32::NetAdmin, or Windows itself. Perhaps you're getting some default that just happens to be what you asked for previously.

You're using too many quotes. The value isn't `"Running"', but rather
`Running'.

The style police are being kept at bay by unrulely Perl
users, who keep chanting "There's More Than One Way To Do
It". ;-) However, sometimes another approach is easier to
maintain/read, so please allow me to have a go.
My version looks like:
# Open workflow.txt (better if we knew what this file was).
open (WORKFLOW, '..\..\workflow.txt') or die "Cannot open
Workflow $!\n";
# Extract 23rd line.
my $line; do {$line = } until $. == 23 || eof;
unless ($. == 23) { die "workflow.txt isn't even 23 lines
long!\n" };
# Find position of "Running" after, but starting at
position 11.
my $position = index($line, "Running", 11);
# Unless it appears between positions 11 and 19 we wish to
send an email.
if ($position == -1 or $position > 19) {
# Send that email NOW!
}
# Close the file now we are finished.
close (WORKFLOW) or die "Cannot close Workflow $!\n";

My version should work just fine, but if you want try:
$. = 20;
do {print "$.: " . } until $. == 26 || eof;

Re: Not creating home dir....
Adding an entry to /etc/passwd on Unix/Linux does not add a home directory
for that user. adduser or useradd or even linuxconf (depending on your
flavor/distribution) takes care of that, but it is a seperate act from adding
a user to /etc/passwd.
That said you do have to add the directory yourself, which is not necessarily
a bad thing, since not all users require a home directory, and you have
complete control over where the directory is created, if at all.
You could even add a few lines to your script to handle special cases, i.e.
non-real users, certain groups etc. :-)

Letting the empty diamond operator work on @ARGV would prevent you
from having to code the open/close. That's the plus side. The minus
side is that you don't have control over the open failure, so you have
to be happy with the built-in version.
This code is *different*, not *better* ---

Whenever you have specific information like that, a regex is often not the
best approach to take.

This discards lines 1 through 21. I thought you wanted to discard the
first 22 lines.
>seek(WORKFLOW, 22, 0); #This will put you at row 23.---
This is not what seek() does.
seek FH, OFFSET, WHENCE;
OFFSET is some number of bytes (not a line number), relative to WHENCE --
if WHENCE is 0, it's OFFSET bytes from the beginning of the file, if
WHENCE is 1, it's OFFSET bytes from the current position in the file, and
if WHENCE is 2, it's OFFSET bytes (you usually want OFFSET to be negative
in this case) from the end of the file.
Your call puts you 22 bytes from the beginning of the file. Not what you
wanted.
If you want to skip the first 22 lines of a file, just do:
for 1 .. 22;
>$_=;
>/("Running")/; #Now if you want, you can also check
> #to make sure that this was found in
> #the right column by checking @- and @+
>if($-[0] == 10 && $+[0] == 18)
You don't need parens around "Running" in your regex. And instead of using
a regex here, why not simply test like so:
$_ = ;
if (substr($_, 10, 8) eq '"Running"') {
# ...
}
You should also never use a regex in void context -- if it fails, you'll
get the results from the previous successful regex shining through:
"jeff" =~ /(ef+)/;
print $1; # "eff"
"joe" =~ /(ef+)/;
print $1; # "eff"

How can I get ahold of the DBI file needed for a ActiveState ppm install?
I have to put DBI and the DBD::ODBC driver on a Windows 2000 Server machine that's running Active State perl. The tricky thing is, the machine is not on the Internet, so I can't use the built in ppm utility to automagically go out and retrieve the ppd files that are used by ppm to build and install the modules. But, if I could grab those ppd files, I could burn them onto a CD, change the repository path on ppm to point at the CD drive, and I'd be in business. My problem is, I can't figure out how to actually get the ppd files. I've searched all through www.activestate.com and can't find them, and the CPAN repositories seem to just have the tar.gz version of the modules. Does anyone have any ideas?

there's a module called Net::SCP, which does scp in perl.
it says:
Q: How do you supply a password to connect with ssh within a perl
script using the Net::SSH module?
A: You don't. Use RSA or DSA keys. See the ssh-keygen(1) manpage
http://theoryx5.uwinnipeg.ca/CPAN/data/Net-SCP/SCP.html
although if you're determined to do it the other way, you could look
at the Expect module: http://search.cpan.org/search?dist=Expect

i haven't used the module, but looking at the documentation it doesn't
say anything about creating the user's home directory.
it looks like you can use Unix::PasswdFile to set the right entries in
/etc/passwd, but you'll have to make sure the directories are there
through other methods.

You can use perl's glob operator (type perldoc -f glob at the command

Wrap your script, except the exit(0) by

Opening multiple files in a directory
Hello,
I have a script that opens a file, performs some "sed"
operations, and then saves the edited file to a new
file name. Currently, I have to supply the names of
input and output files, within the script.
My question: I would like to be able to have the
automically open all the files in a given directory,
one at a time, perform the "sed" operations, and then
save them to the directory. How can I do this ?
Here is the script:
#!/usr/bin/perl -w
open (IN,"< orig_names.txt");
open (OUT,">mod_names.txt");
while () {
chomp;
if ($_=~/^lname/i) {
s/holt/henning/;
s/shultz/stultz/;
}
}
close (IN);
close (OUT);
exit(0);
I would greatly appreciate your help in this regards.
Thanks

I cannot help you with funky perl... But is a classic programming problem
from the days of tape streamers and COBOL. It is called a `merge' ,
suprisingly. This is a very efficient way to merge large amounts of data.
The only gotcha is that the files must be sorted on the merge key (ie TIME),
which I am happily asuming since it is a timestamp. There might be the odd
ocasion that the input files are not sorted( Machine bounced and the BIOS
clock resets itself). Putting a sorted file thru a quick sort uses virtually
no resources, and then you will be garanteed to get the correct results.
This is a lot more typing but classic algorithms are such joy to code.. (For
me anyway);
Pseudo code:
open file1, file2
(time1, input1, output) = read file1
(time2, input2, output2) = read file1
while not end of file file1 and file2 {
if (time1 == time2 {
input = input1 + input2
readboth = true;
}
if (time1 < time2) {
input = input1
read1 = true;
}
if (time2 < time1) {
input = input2
read2 = true;
}
write summary with input
if (read1 || readboth ) {
if not eof file1 then (time1, input1, output) = read file1
};
if (read2 || readboth ) {
if not eof file2 (time2, input2, output2) = read file1
}
readboth, read1, read2 = false
}

The easiest way would be to use a hash:
#!/usr/bin/perl -w
use strict;
my %data;
for my $file ( '/data/table1', '/data/table2' ) {
open IN, "< $file" or die "Cannot open $file: $!";
while ( ) {
my ( $time, $in, $out ) = split;
$data{ $time }[0] += $in;
$data{ $time }[1] += $out;
}
close IN;
}
for ( sort keys %data ) {
print "$_ @{$data{$_}}\n";
}

I think that you can probably achieve this in a more secure way by altering
your scp/ssh configuration. Having a quick look at the man page for my
version of scp (running under Cygwin on Windows NT), you can operate scp in
batch mode (by giving it the command line argument -B) which prevents it
from asking for passwords or pass phrases. I would guess that you would
still need an authentication mechanism in place though...
It is possible to configure scp/ssh so that instead of needing a password,
you use public/private key authentication. 'man ssh' and look at the section
on RSA authentication.
The advantage of this is that you don't need to store your password in plain
text anywhere on you system.

Best DBI for newbie
I am looking for the best way to connect to a MS SQL 7 database from a remote Win2000 machine. I have looked at DBI::ODBC.pm / Win32::ODBC.pm, but the documentation is kinda weak for the win32 ports. I have used the DBI::Oracle driver, so I can reference that. --- Scott Lutz ---
