The C-shell offers a number of special commands known as control codes. Control codes define commands specific to the operating system. To issue a control code, hold down and press the corresponding letter key. The following summarizes some of the most commonly used control codes:
 d Signals the end of a file you are entering from the terminal if typed at the beginning of a line or if typed twice elsewhere in a line.
 c Cancels a command or interrupts a running program.
 z Suspends a process or job but does not terminate it: use fg to restart suspended process or job.
common_alias myscreen '~/bin/screen'
common_alias ls   'ls --color=auto'


common_alias findfile    'find . -follow -type f | grep $*'
common_alias findtext 'find . -not -name "*.d" -not -name "*.o" -not -name "*.a" -follow -type f -print0 | xargs --null grep $*'

Yum is usually already installed if you're running Fedora Core. In case you are using Red Hat Enterprise Linux or an older Red Hat Linux distribution. You can find Yum at: http://dag.wieers.com/packages/yum/

The configuration of Yum is inside the rpmforge-release package. You need to install it yourself.

If you've done that, the rest is simple. Upgrade your system by doing:

yum update

You can add new software by typing:

yum install

Or update installed software:

yum update

Or search for software in the local repository meta-data:

yum search

Or simply list all available software:

yum list available

From time to time you may want to save some diskspace:

yum clean

Hi,

I am currently following the advice at ThinkWIKI to get it working on my X61 tablet with Ubuntu 8.04.1 (everything else works great!).

My problem is that since I have 2.6.24 (which has some issues with the kernel patch) I am trying to use the Zen-Sources kernel.

However the kernels don't seem to be .tar.bz2 but rather .patch.bz2 meaning the
Code:

# tar jxf 2.6.27-rc7-zen3.patch.bz2

just reports back with an error complaining about it not being a tar file.

    How to List my tables in Oracle database

http://www.dba-oracle.com/bk_sqlplus_list_tables_views.htm

SELECT * FROM all_tables; <- all tables you have access to
SELECT * FROM user_tables; <- all tables owned by currently logged in user
SELECT * FROM dba_tables; <- all tables in database


I am glad to know that we have Database forum here.

Just installed Oracle database server under Ubuntu Linux, It did took some time but finally beast is installed.

Now how do I list tables? Mysql has
Code:
SHOW DATABASES;
USE mydb;
SHOW TABLES;
SELECT * FROM mytable;
So far I am able to login into the Oracle using command-line tool called SQL*Plus:
Code:
$ sqlplus scott/tiger
Now how do I list tables?

I am just taking print out of Oracle sql pdf but please give me command so that I know it is working.

To list all your tables in Oracle server, use the following command:
Code:
SELECT * FROM cat;
First connect to server using Oracle sql plus client:
Code:
sqlplus scott/tiger
Now type at sql> prompt:
Code:
SELECT * FROM cat;
Also don't forget to set the column widths
Code:
COL table_name FORMAT a30;
COL table_type FORMAT a30;
Now to get list of tables in oracle:
Code:
SELECT * FROM cat;

I love the Drupal CMS. One of my favorite features of Drupal is the ability to do a multisite install. This site and my other blog, i <3 stella, are hosted on the same box, using the same Drupal install. Several sites can share one codebase. Updates are easily rolled out to every site simultaneously. Overall, it's a wonderful idea. But I have some problems with the implementation...

The standard way to set up a multisite install is to point each of the domain names at the Drupal install folder and let Drupal sort out which domain each request is coming from. It does a good job, too. But this method introduces some complications. For example, any content uploaded to site a is accessible from site b. A user that visits http://site1.com/myimage.jpg will find the same image as she finds at http://site2.com/myimage.jpg. Websites can't have domain specific .htaccess or robots.txt files either, which might hurt search engine optimization of individual sites.

An interesting side effect of this is if you want to install something in a subdirectory of your site, for example a WordPress blog at http://site1.com/blog, that exact same WordPress blog will exist in its full glory at http://site2.com/blog...

Another, and perhaps more grave, problem is that all that stands between the interweb and your very own personal settings is an .htaccess file. Install scripts, includes, site configurations and database passwords are in web accessible directories, and that is never a good thing.

We'll look at one solution to these problems.

I assume here that you are using Linux hosting, that you have shell access, and that you have at least a passing acquaintance with symlinks. If you're looking for a webhost that meets these requirements, check out 1and1 shared hosting. I've been happy with them, and all of their packages above $9.99/mo will do what you need.

Microsoft/IIS guys, you can't do a symlink. You're looking for something called a junction... good luck with that.
