Checking the Machine's Operating System
Hi Folks, I have a requirement from the clinet where in i have to take control of the machines (either by telnet,SSH). My first point to be addressed is how can i take a remote machine TELNET through perl script and also once i take the same i have to check the type of operating system and then find the size of the disks partitioned. Waiting for your help at the earliest Thanks in Advance Mazhar

Re: ?php???
JupiterHost.Net: PHP has very few templating systems and they just kill php's biggest advantage [...] There are plenty of PHP templating systems, and coding PHP gets a lot more pleasant with a good template system. I think what he meant was, most PHP template systems are simply drop in php scripts that are normal PHP that gets done (IE include()ed) as part of the page. I was thinking WASP, or Smarty, or some in PEAR. http://wasp.sourceforge.net/ http://smarty.php.net/ http://pear.php.net/search.php?q=template Oh gotcha :) Sure PHP has API's to template systms done in other languages and probably some doenn all in PHP, Perl has those too, but using them doesn't destroy the entire reason you'd want to use it in the first place. See? Very dumb PHP is, use it not. I consider this strange reasoning. Templates are about effectivity. When it is effective to do what you need to do in little new code, go for templates. Nothing needs to be destroyed in that process. If you did use a real templating system with PHP thats when you just kill php's biggest advantage because now there's no need for its embedded in HTML funtionality, bottom line: PHP blows :) Yes, there are more ways to separate application logic and content from its presentation. Right by killing the biggest feature it has :) What is killing what, in your point of view? Those templates generate both HTML and PHP, like code that gets some fresh data from some database. Templates are used for part of the system. Another advantage of perl which was not pointed in that web page is that perl has perldoc The PHP documentation at http://www.php.net/manual/en/ is very practical. What if you are coding on a machine without an internet connection? Downloadable in many formats and languages. http://www.php.net/download-docs.php But what if you are coding on a machine without an internet connection :) ? Where has the difference with perldoc gone? A default PHP installation includes the documentation. -- Affijn, Ruud Gewoon is een tijger. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response
Execute newgrp system command
Hi, I want to login into a new group using 'newgrp' UNIX command.Every newgrp command invokes a new shell. But when I am trying to execute this system command from a perl script the script is terminating and returning the prompt of the new shell .

Long answer: The newgrp command will always run a new shell regardless if it succeeds or fails. What you can do instead is set the effective group id for the script. 1. Change the script's group to the group you want it to work under (see `man chgrp`). 2. Change the script's set group id on execution flag (see `chmod`). The script will now run under the new group.

Long answer: The newgrp command will always run a new shell regardless if it succeeds or fails. What you can do instead is set the effective group id for the script. 1. Change the script's group to the group you want it to work under (see `man chgrp`). 2. Change the script's set group id on execution flag (see `chmod`). The script will now run under the new group.

Jeff very nicely replicated what you were trying to do, that is, separate out the year, month, and day, and rearrange them to your liking. Roberto, on the other hand, gave you code to match your end result, not your process. Roberto's is more efficient--there's one less substring function on each pass, which may or may not make a difference if you're doing thousands of passes. Jeff's on the other hand, more closely mirrors what you were trying to do yourself. Obvously at some point you though it was important to handle the three pieces of the date separately, and Jeff's code is more flexible. Which makes most sense for your current application only you know. If lots of dates are in your future--and they probably are; dates are a common problem--what you probably really want to do is take a look at Date::Calc, Date::Manip, Date::Parse, etc. HTH, -- jay -- This email and attachment(s): [ ] blogable; [ x ] ask first; [ ] private and confidential daggerquill [at] gmail [dot] com http://www.tuaw.com http://www.dpguru.com http://www.engatiki.org values of β will give rise to dom!

about deleting subroutine
hi,lists,
I have seen this thread on perlmonk,and it make me confused too.Can anyone here
explain that?Thanks.
Quote:
---
Basically, deleting subroutines from a symbol table seems a bit buggy, but I
don't know if this behavior is documented or not.
#!/usr/bin/perl -l
sub this { 'this' }
print this;
undef main::this; # undefine the code slot
print main-can('this') ? 'main-can(this)' : '! main-can(this)';
eval {print this};
print $@;
undef *main::this; # undefine the entire glob
print main-can('this') ? 'main-can(this)' : '! main-can(this)';
__END__
# result
this
main-can(this)
Undefined subroutine main::this called at sub.pl line 7.
! main-can(this)
The first time I try to remove the subroutine via undef it still leaves a
CODE slot in the symbol table's *this glob. I can't just use delete because it's
not an array or a hash (it fails if you try). This is bad in procedural code but
it's awful in OO code because $object-can('this') will succeed even if the
method has been deleted.
This leaves me with having to undefine the entire glob but that's a
horrible solution because the other slots in the glob, if any, are blown away.
Is this a known/documented bug/feature in Perl? Is there a workaround?

RE: File Finding
Don't forget that each module has documentation that can be accessed via 'perldoc Module::Name' So try 'perldoc File::Find' (without the quotes) at the command-prompt. Hint: Check the section called The Wanted Function. For the file size, you will probably use the stat function. One way to do this is to use an array slice like so: my $dirsize = (stat $_)[7]; Hint: File::Find sets $_ to the current filename. Do a 'perldoc -f stat' to see what the other elements are that might be useful. 7 is the file size in bytes. Remember that the Wanted function (BadNames in your case) will execute for each file. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, November 21, 2005 1:38 PM To: beginners@perl.org Subject: File Finding Hello I got the file command to work but it is not as complete as I would have hoped for.

Re: ?php???
PHP has very few templating systems and they just kill php's biggest advantage [...] ... Oh gotcha :) Sure PHP has API's to template systms done in other languages and probably some doenn all in PHP, Perl has those too, but using them doesn't destroy the entire reason you'd want to use it in the first place. See? Very dumb PHP is, use it not. I consider this strange reasoning. Templates are about effectivity. When it is effective to do what you need to do in little new code, go for templates. Nothing needs to be destroyed in that process. Templates are good and the poitn is: PHP's main advantage is embedded PHP/HTML + using a template systems make the embedded garbage useless = PHP is useless :) If you did use a real templating system with PHP thats when you just kill php's biggest advantage because now there's no need for its embedded in HTML funtionality, bottom line: PHP blows :) Yes, there are more ways to separate application logic and content from its presentation. Right by killing the biggest feature it has :) What is killing what, in your point of view? Those templates generate both HTML and PHP, like code that gets some fresh data from some database. Templates are used for part of the system. Right, if you're using templates of some sort then dump PHP (IE get rid of all of tis really negative and many times dangerous stuff) and use *any* other langauge that can also do templates and doesn't have its negative attributes. Another advantage of perl which was not pointed in that web page is that perl has perldoc The PHP documentation at http://www.php.net/manual/en/ is very practical. What if you are coding on a machine without an internet connection? Downloadable in many formats and languages. http://www.php.net/download-docs.php But what if you are coding on a machine without an internet connection :) ? Where has the difference with perldoc gone? A default PHP installation includes the documentation. I see, so why the urls then :) -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

Hi All~
Hello,
I'm trying to get my head around local $/ = ''; #enable paragraph mode.
Did you read the documentation for it in perlvar.pod?
perldoc perlvar
Is there anything in the documentation that you don't understand?
If I have a tab delimited file that looks like this:
1311001
Aed Motorsports
5373 W 86th St
Indianapolis, Indiana 46268 U.S.A.
7069210
Bird Electronic

1020700
Charis Disk Golf
Ste 160-135
4000 W 106th St
Carmel, Indiana 46032 U.S.A.
and code that looks like this:
local $/ = '';
while (OLD) {
my @rows = split /\n/;
print SAVESTDOUT join(\t, @rows), \n;
You don't have to split() and join() the data, this would be more efficient:
chomp;
tr/\n/\t/;
print SAVESTDOUT $_\n;
}

Basically, deleting subroutines from a symbol table seems a bit buggy, but I

Re: Execute newgrp system command
Hi, Thanks for the suggestion. There are some tasks which are directly tied to the group-id. Owing to the requirement it may happen my perl script need to switch groups to achieve a specific task. So my plan is to change to a new group with new grp command after exporting the Environment/required variables from the current shell. After the newgrp system command from a perl script could not satisfy my need I tried including the command in a separate .cshrc file and then just sourcing that file from a perl script. But this job could not again be executed from perl script . The perl script returns error telling the sourced file could not be found. Moreover changing the scripts group permission wont do hold good for my case. I am at bay now !!

But when I am trying to execute this system command from a perl script the script is terminating and returning the prompt of the new shell . Can anyone suggest on what can be done to change into a new group from within perl script? Short answer: You can't. Long answer: The newgrp command will always run a new shell regardless if it succeeds or fails. What you can do instead is set the effective group id for the script. 1. Change the script's group to the group you want it to work under (see `man chgrp`). 2. Change the script's set group id on execution flag (see `chmod`). The script will now run under the new group.
