Email Validation
I've been working on email validation for a script. The examples I've seen
haven't exactly done that great of a job. I've taken the code and messed
with it some.
My thoughts were, if the email is in the correct format,
ie [EMAIL PROTECTED] or some form like [EMAIL PROTECTED] then go
to the second 'if' statement and check for bad characters.
It seems to work how I want, have I caught most of the problems? I'm only
interested in the email address, not checking to see if this is
valid: roger [EMAIL PROTECTED]
sub valid_email ()
{
if ($e_address =~ /^\w+(\.\w+){0,}\@\w+(\.\w+){1,}$/i)
{
if ($e_address =~ /\'\{\}\[\]\(\)\$\%*/i)
{
return 0;
}
return 1;
}
return 0;
}

But not enough. :)

That ignores fred[EMAIL PROTECTED], a valid and active email
address. (Try it! It's an autoresponder!)
It permits [EMAIL PROTECTED], an invalid email address.
Definitely wanna look at those other modules.
I hadn't found that module when I was searching the net. the
Email::Validdoesn't catch the @this_host.com It also doesn't catch |
in the email, which I would've thought shouldn't be permitted.
I'll keep digging.

Re: How to abut two files?
At 06:18 PM 1/30/2002 -0500, you wrote: One of the most common needs in data analysis is to abut two files. This means to create a single file by horizontally pasting two files together. So: starting with two files each with, say, 4 columns and 4 rows, the result is one file with 8 columns and 4 rows. For a couple decades now I've relied on Gary Perlman's stat utilities (specfically, the abut program) to do this in a unix environment. How to do it on a macintosh? I'd like to avoid having to use a program like microsoft excel. I'm wondering if perl has the ability to abut two files. I've downloaded perl, but before trying to master it, I'm hoping someone knowledgeable would be willing to tell me if (and how) perl can easily abut two files. Essentially, you would go through both files a line at a time printing to a third file. first reading the first file, print, read second file, print etc. for each line. Which Mac OS do you have? X should have perl by default. Roger -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Sendmail and PERL
chmod 700 should do it. Any group or world writable should kill it. I don't think sendmail complains about readable files as much as it does about writable files. What do the logs say? One other way is via a procmail recipe. Something like: :0 * /path/to/perlscript Roger At 08:15 AM 1/17/2002 -0800, you wrote: First thing I would do is check the permissions of the .forward file.

If anyone can give me information or even point me to a sendmail list or resource I would appreciate it. I am writing a PERL script that takes incoming mail, parses the contents, and then uses them to update a status page. I thought the sendmail part would be as simple as adding a |/path/to/script.pl to the aliases file. Unfortunately, I do not even have read access to the aliases file on my webhost's computer. I called them and they told me I could accomplish the same thing with a .forward file, but that they could not tell me how. So I tried making a .forward file in my home directory with the line I would have put in an aliases file. But this didn't work. Does anyone have any ideas, or resources on this?

Script Idea
I've got a laptop running Linux. When I go to work, the laptop gets it's IP address via DHCP, at home I have a private IP address that I use (for a home network that uses dial up for Internet), and at my other place of employ I have a third IP address that is used. I've created a shell script that will prompt for where I am located, then sets the host information appropriate for my location (home,work1,work2). I was thinking of automating it somewhat but wanted to get some ideas before I proceed. My thought is to create a script that would set the IP address to work2 IP, then check to see if the gateway that's in use is available, if it's not then set to the private IP for home and see if one of the other computes is visible. If none of the first two work, then assume it's DHCP and set the files; of course, non of this takes into account I may boot the computer with it not being part of any network. I'd check for DHCP first, but if it's not available, I don't want to wait for the dhcp timeout to occur. Question, Is it more trouble than it's worth to set something like this up? Does the basic logic of what I want to do look okay? Any thoughts? Roger -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The web site says there is an upgrade to fix a security problem. What problems are you having? The problem that I saw was that the script takes the email address that is embedded in the form and mails the form to that person. The problem is, someone off-site could create a form that points to the script and send via your mail program (can you say spam). One work around is to hack the code such that the recipient is hard-coded in the script, not the form.

combine commands
Hi, Just trying to un-clutter some code. Following is the relevant part: $ucscode is assigned a value via a split on : There could be white space at the begging and end of the value. the value could be Upper case. The end result should be no white space, all lower case. There may or may not be a line-feed. the result ends up in $scode. I have: my $ucscode; my $scode; split chomp $ucscode; # remove line-feed $ucscode =~ s/^\s+|\s+$//g; # remove spaces $scode=lc($ucscode);# make lower case. Can this series be done with one variable? Can this be done on one line? Thanks. Roger -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
