# netstat -ntl

The output will look something like

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State

Run the following command to redirect port 80 traffic to port 8080

# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

Run the folloing command to verify that redirect is working fine

# iptables -t nat -L

The output will look something like

Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
REDIRECT   tcp  --  anywhere             anywhere            tcp dpt:http redir ports 8080

Chain OUTPUT (policy ACCEPT)

# yum install tomcat6-webapps

Tomcat will get installed across the following directories

/etc/tomcat6             conf files     $CATALINA_HOME/conf
/usr/share/java/tomcat6  libs           $CATALINA_HOME/lib
/usr/share/tomcat6/bin   executables    $CATALINA_HOME/bin
/var/log/tomcat6         logs           $CATALINA_HOME/logs
/var/cache/tomcat6/temp  temp files     $CATALINA_HOME/temp
/usr/share/tomcat6       home directory $CATALINA_HOME
/var/lib/tomcat6/webapps web apps       $CATALINA_HOME/webapps
/var/cache/tomcat6/work  compiled stuff $CATALINA_HOME/work

Set CATALINA_HOME in /etc/profile

export CATALINE_HOME=/usr/share/tomcat6

Tomcat can be stopped, started and restarted using the following commands

# service tomcat6 stop
# service tomcat6 start
# service tomcat6 restart


# cat /proc/version

The output will be something like this:

Linux version 2.6.35.11-83.9.amzn1.i686 (mockbuild@build-31004.build) (gcc version 4.4.4 20100726 (Red Hat 4.4.4-13) (GCC) ) #1 SMP Sat Feb 19 23:41:56 UTC 2011


Specify a function to execute when the DOM is fully loaded.

$(window).load(function(){
//code
});

Specify a function when the page is fully loaded including graphics.

Step 1 : Go to the command prompt (Start > All Programs > Accessories > Command Prompt)

Step 2: CONVERT E: /FS:NTFS

In the example above, the E drive will get converted to NTFS.

show table status 

This statement also displays information about views.

SHOW TABLE STATUS returns the following important fields along with a lot of other intersting data:

Engine
The storage engine for the table. See Chapter 13, Storage Engines.

Rows
The number of rows. Some storage engines, such as MyISAM, store the exact count. For other storage engines, such as InnoDB, this value is an approximation, and may vary from the actual value by as much as 40 to 50%. In such cases, use SELECT COUNT(*) to obtain an accurate count.

Avg_row_length
The average row length.

Data_length
The length of the data file.

Rename command usage:

rename oldname newname *.files

Some examples:

Rename all *.abc file as *.xyz:

$ rename .abc .xyz *.abc

Remove .txt file extension:

$ rename 's/\.txt$//' *.txt

Convert all uppercase filenames to lowercase:

$ rename 'y/A-Z/a-z/' *

Frequency- 5 GHz  
Typical Data Rate - 23 Mbit/s  
Max Data rate – 54 Mbit/s  
Range – 115 feet

(B) 802.11b
Frequency - 2.4 GHz  
Typical Data Rate - 4.5 Mbit/s  
Max Data rate – 11 Mbit/s  
Range - 115 feet

(G) 802.11g
Frequency - 2.4 GHz

Type the following at the prompt with the appropriate USERNAME and DATABASE name:

mysqldump -u USERNAME -p DATABASE > dump.sql

You will be prompted for your database password and then the DATABASE will be dumped to a plain-text file called dump.sql.

Restoring via the command line:

First drop and recreate the database as needed:

Drop the database

mysqladmin -u USERNAME -p drop DATABASE

Recreate the database

mysqladmin -u USERNAME -p create DATABASE

Import the backup data

mysql -u USERNAME -p DATABASE < dump.sql

Setting JAVA_HOME and PATH for a single user

# vi ~/.bash_profile
# export JAVA_HOME=/opt/jdkx.x.x_xx
# export PATH=$PATH:$JAVA_HOME/bin

Setting JAVA_HOME and PATH for all users

# vi /etc/profile
# export JAVA_HOME=/opt/jdkx.x.x_xx
# export PATH=$PATH:$JAVA_HOME/bin

Method 1:

command:

# echo $SHELL

output:

/bin/bash

Method 2:

command:

# echo $0

output:

-bash

Method 3:

command:

# ps -p $$

output:

 PID TTY               TIME CMD
1447 tty1          00:00:01 bash

Run Command Prompt and type the comman MKLINK.

If the system warns saying…“You do not have sufficient privilege to perform this operation”. Run the Command Prompt as Administrator

Usage:

MKLINK [[/D] | [/H] | [/J]] Link Target
        /D      Creates a directory symbolic link.  Default is a file
                symbolic link.
        /H      Creates a hard link instead of a symbolic link.
        /J      Creates a Directory Junction.
        Link    specifies the new symbolic link name.
        Target  specifies the path (relative or absolute) that the new link
                refers to.

Example: To create a directorty link called src what points to c:\users\foo\src

     mklink /D src c:\users\foo\src
Thats it!

Twitter is a free social networking and micro-blogging service that allows users to send updates (otherwise known as tweets) which are text-based posts of up to 140 characters in length.
