Content Management Systems (CMS)

A content management system (CMS) is computer software used to create, edit, manage, and publish content in a consistently organized fashion. CMSs are frequently used for storing, controlling, versioning, and publishing industry-specific documentation such as news articles, operators' manuals, technical manuals, sales guides, and marketing brochures. The content managed may include computer files, image media, audio files, electronic documents, and Web content.


Web content management system

A Web content management system is a CMS designed to simplify the publication of Web content to Web sites, in particular allowing content creators to submit content without requiring technical knowledge of HTML or the uploading of files.

Details of few CMSs

1. Joomla!

Joomla is a free, open source content management system for publishing content on the world wide web and intranets. The system includes features such as page caching to improve performance, RSS feeds, printable versions of pages, news flashes, blogs, polls, website searching, and language internationalization. Joomla is licensed under the GPL, and is the result of a fork of Mambo.

It is written in the PHP programming language and uses the MySQL database by default.

2.Plone (software)

Plone is a free and open source content management system built on top of the Zope application server. It is suited for an internal website or may be used as a server on the Internet, playing such roles as a document publishing system and groupware collaboration tool.

Plone is released under the GNU General Public License (GPL) and is designed to be extensible. Major development is conducted periodically during special meetings called Plone Sprints. Additional functionality is added to Plone with Products, which may be distributed through the Plone website or otherwise. The Plone Foundation owns and protects all copyrights and trademarks. Plone also has legal backing from the council of the Software Freedom Law Center.

Commands from Remote Shell: rsh

The remote shell command rsh allows you to execute a command on a remote machine without actually logging onto that machine. The command rsh uses the same .rhosts file as does rlogin, yet while rlogin will prompt you for a password if it has trouble with the .rhost file, both rsh and rcp require a properly functioning .rhosts file. If the .rhosts files is not properly configured, these commands will issue an error message and quit.

leo$ rsh user@server command

example :

leo$ rsh user@server df -h

How to mount a USB flash drive in GNU/Linux

Ubuntu "Hardy" detects Sony Ericsson Mobile but not auto mounts it's 1 GB card, might be the only case with my Linux Box. Because previously it use to auto mount.

Following command list USB devices that are detected by system.

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000



# fdisk -l

which ( FDISK ) will list all the devices including the USB devices detected by GNU/Linux. Then you can use the mount command to mount it at a specific location.
