Python in particular suffers from library-itis. If there's something which can be done, there's not just one but several conflicting libraries preinstalled for you.
C is more of a "do it yourself" language. It doesn't really lend itself to one-liners. But it gives you a level of control scripting languages don't.

Hi
On several AIX 5.3 LPARs the timezone is currrently set to:
TZ=NZST-12NZDT,M9.5.0/02:00,M4.1.0/03:00
Daylight savings in NZ starts on Sun 28th Sep 2008, which is the fourth Sunday. Do I need to change my TZ variable to NZST-12NZDT,M9.4.0/02:00,M4.1.0/03:00 or will AIX interpret the fifth... (2 Replies)
I am not a Unix / AIX admin, but am working with one that doesn't seem to know how to set up syslog to forward messages to me the way I need them. Every message they send me has "Message forwarded from <insert host name here>:" but I need it to only have the host name.
In the examples below,... (2 Replies)
Hi,
I had to setup some cron jobs using crontab -e when logged in as root.
I noticed that the jobs only run when the permissons on the shell script file are set to execute on root and other. Why does "other" have to have its execution permission set? (6 Replies)
I need to "sync" a directory from a prod server to a test server. Rsync is working but it prompts for a password and I'd like to automate the process. The directory on the prod/source server is owned by root, and some subdirectories are only readable by root. On the test/destination servers, I can... (1 Reply)
Hi there
There's a script I would like to run daily every 5 minutes and this job should restart every 12:03AM so it would append to a new file with the following day date format instead of running and updating continuously into one log. I am not sure of the syntaxing, what I did was to set it... (9 Replies)
I have a Win7 laptop that I have installed Xming with Xlaunch so that I can remote a Solaris10 server. After the initial install on my Win7 machine what do I need to set and configure to be able to remote Solaris. This is my 3rd day working with Unix. (1 Reply)
Trying to figure out the best method of security for oracle user accounts. In Solaris 10 they are set as regular users but have nologin set forcing the dev's to login as themselves and then su to the oracle users.
In Solaris11 we have the option of making it a role because RBAC is enabled but... (1 Reply)
I communicate with the server via a ssh tunnel, configured via Putty.
Recently, I'm trying to forward the X11 through it, but it doesn't work.
Is there any one work this way?
Searched with google, but didn't find anything.
Thx in adv. (2 Replies)

LWP::Simple(3) User Contributed Perl Documentation LWP::Simple(3)NAME
LWP::Simple - simple procedural interface to LWP
SYNOPSIS
perl -MLWP::Simple -e 'getprint "http://www.sn.no"'
use LWP::Simple;
$content = get("http://www.sn.no/");
die "Couldn't get it!" unless defined $content;
if (mirror("http://www.sn.no/", "foo") == RC_NOT_MODIFIED) {
...
}
if (is_success(getprint("http://www.sn.no/"))) {
...
}
DESCRIPTION
This module is meant for people who want a simplified view of the libwww-perl library. It should also be suitable for one-liners. If you
need more control or access to the header fields in the requests sent and responses received, then you should use the full object-oriented
interface provided by the "LWP::UserAgent" module.
The following functions are provided (and exported) by this module:
get($url)
The get() function will fetch the document identified by the given URL and return it. It returns "undef" if it fails. The $url
argument can be either a simple string or a reference to a URI object.
You will not be able to examine the response code or response headers (like 'Content-Type') when you are accessing the web using this
function. If you need that information you should use the full OO interface (see LWP::UserAgent).
head($url)
Get document headers. Returns the following 5 values if successful: ($content_type, $document_length, $modified_time, $expires, $server)
Returns an empty list if it fails. In scalar context returns TRUE if successful.
getprint($url)
Get and print a document identified by a URL. The document is printed to the selected default filehandle for output (normally STDOUT) as
data is received from the network. If the request fails, then the status code and message are printed on STDERR. The return value is
the HTTP response code.
getstore($url, $file)
Gets a document identified by a URL and stores it in the file. The return value is the HTTP response code.
mirror($url, $file)
Get and store a document identified by a URL, using If-modified-since, and checking the Content-Length. Returns the HTTP response code.
This module also exports the HTTP::Status constants and procedures. You can use them when you check the response code from getprint(),
getstore() or mirror(). The constants are:
RC_CONTINUE
RC_SWITCHING_PROTOCOLS
RC_OK
RC_CREATED
RC_ACCEPTED
RC_NON_AUTHORITATIVE_INFORMATION
RC_NO_CONTENT
RC_RESET_CONTENT
RC_PARTIAL_CONTENT
RC_MULTIPLE_CHOICES
RC_MOVED_PERMANENTLY
RC_MOVED_TEMPORARILY
RC_SEE_OTHER
RC_NOT_MODIFIED
RC_USE_PROXY
RC_BAD_REQUEST
RC_UNAUTHORIZED
RC_PAYMENT_REQUIRED
RC_FORBIDDEN
RC_NOT_FOUND
RC_METHOD_NOT_ALLOWED
RC_NOT_ACCEPTABLE
RC_PROXY_AUTHENTICATION_REQUIRED
RC_REQUEST_TIMEOUT
RC_CONFLICT
RC_GONE
RC_LENGTH_REQUIRED
RC_PRECONDITION_FAILED
RC_REQUEST_ENTITY_TOO_LARGE
RC_REQUEST_URI_TOO_LARGE
RC_UNSUPPORTED_MEDIA_TYPE
RC_INTERNAL_SERVER_ERROR
RC_NOT_IMPLEMENTED
RC_BAD_GATEWAY
RC_SERVICE_UNAVAILABLE
RC_GATEWAY_TIMEOUT
RC_HTTP_VERSION_NOT_SUPPORTED
The HTTP::Status classification functions are:
is_success($rc)
True if response code indicated a successful request.
is_error($rc)
True if response code indicated that an error occurred.
The module will also export the LWP::UserAgent object as $ua if you ask for it explicitly.
The user agent created by this module will identify itself as "LWP::Simple/#.##" and will initialize its proxy defaults from the
environment (by calling $ua->env_proxy).
CAVEAT
Note that if you are using both LWP::Simple and the very popular CGI.pm module, you may be importing a "head" function from each module,
producing a warning like "Prototype mismatch: sub main::head ($) vs none". Get around this problem by just not importing LWP::Simple's
"head" function, like so:
use LWP::Simple qw(!head);
use CGI qw(:standard); # then only CGI.pm defines a head()
Then if you do need LWP::Simple's "head" function, you can just call it as "LWP::Simple::head($url)".
