A New look to Windows Command line tutorial

Windows PowerShell is a new command line shell and task-based scripting technology that provides information technology (IT) administrators comprehensive control and automation of system administration tasks, increasing administrator productivity.

Windows PowerShell includes numerous system administration utilities, consistent syntax and naming conventions, and improved navigation of common management data such as the registry, certificate store, or Windows Management Instrumentation (WMI). Windows PowerShell also includes an intuitive scripting language specifically designed for IT administration.

Supported Platforms:

• Windows XP Service Pack 2,
• Windows Server 2003 Service Pack 1,
• Windows Server 2003 R2,
• Windows Vista,
• and Windows Server 2008.

The main advantage of PowerShell ISE is that you can work within two panes:

• one for typing commands
• and one where the output results are displayed.
• There is a third pane for editing scripts, but you can disable it, so as to have more space for the output pane.

Protect your Computer from Virus

• Use a high-quality anti-virus program, and be sure to update it regularly. Use it to scan any files, programs, software, or diskettes (even new software from a commercial company) before you use them on your computer.
• Make back-up copies of important documents or files and store them on separate diskettes. Making backups will also protect your information against accidental file deletion, diskette failure, and other damage.
• Whenever you use a computer in a campus lab, be sure to reboot or run “cleanup” before you start your session and log out when you end your session.
• Do not share commerical software with anyone. It is a violation of the author’s copyright to distribute such material, and it is a way to spread viruses.
• When you get public domain (PD) software for which the author has granted permission to make copies, get it from a reliable source. (For example, and individual you do not know is not a reliable source.) Before you run PD material, use an anit-virus program to inspect for known viruses.
• Always scan your disks and files after using them on another computer.
• Always scan all files you download from the Internet.
• Always scan Word or Excel file email attachments before you read them.

Disaster recovery Plan

filed in Disaster recovery on Feb.21, 2009

Disaster recovery is the process, policies and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster.

Disasters can result from events such as

• hacker attacks
• computer viruses
• electric power failures
• underground cable cuts or failures
• fire, flood, earthquake, and other natural disasters at a facility
• mistakes in system administration

An IT disaster recovery plan takes into account the need to

• detect the outages or other disaster effects as quickly as possible
• notify any affected parties so that they can take action
• isolate the affected systems so that damage cannot spread
• repair the critical affected systems so that operations can be resumed
