Getting client and server sessionId in JSF
Code for Generating ClientSide SessionId:
var sesid = document.cookie;//this will give client sessionid and stores in sesid variable
Code for Generating ServerSide SessionId:
//this method will return the server side session id using getId() method
private String serverSessionid() {
HttpServletRequest hrq = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
HttpSession session = hrq.getSession();
rtnString = session.getId();
//System.out.println("SESSION ID"+rtnString);

In JavaScript:
function clntCookie(){
var sesid = document.cookie;//this will give client sessionid and stores in sesid variable
document.getElementById("tf_CheckValue").value = sesid;//assigning sesid value to the tf_CheckValue which is inputhidden field
}

Giving Read,Write and Edit permission to a folder in linux
open the terminal
navigate to the particular folder to which we should give permission say validator folder
[subin@wipro-049cafd91 Desktop]$ chmod 777 validator
This will give read, write and edit permissions to validator folder, but the folders(sub folders) present inside the validator folder we don't have permission to access, again we have to do chmod for each and every subfolder
In-order to overcome this problem, we have to use following command
[subin@wipro-049cafd91 Desktop]$ chmod -R 777 validator
This will give read,write and edit permissions to entire folder, including subfolders and files

SCP Command in Linux
scp stands for secure copy, which is a remote file copy program
The scp command allows you to copy files over ssh connections. This is pretty useful if you want to transport files between computers, for example to backup something.
The scp command can be used in three ways:
1.To copy from a (remote) server to your computer
scp -r [login name@ip address] : [/path/filename] .
Ex: scp -r sravan@10.1.14.36:/home/sravan/Desktop/test /home/subin/Desktop
Ex: scp -r sravan@10.1.14.36:/home/sravan/Desktop/test .
Here are the meaning of scp command options:
* -r = recursively copy entire directory
* . = current directory
'/path/filename' is the complete directory path and name where the file resides.
'login name@ip address ' is the target/destination computer. You have to provide your login name and ip address and will be asked for user password.
Dot (.) at the end of the command means the files will be copied to the current directory. Of course you can change the destination to any directory you wish, just type the full path and directory name to replace the dot(.).
2.To copy from your computer to a (remote) server
scp -r [/path/filename] [login name@ip address] : .
Ex : scp -r /home/subin/Desktop/abc sravan@10.1.14.36:.
Ex : scp -r /home/subin/Desktop/abc sravan@10.1.14.36:/home/sravan/Desktop
3.To copy from a (remote) server to another (remote) server.
In the third case, the data is transferred directly between the servers; your own computer will only tell the servers what to do.
scp yourusername@yourserver:/home/yourusername/examplefile yourusername2@yourserver2:/home/yourusername2/
Ex : scp sravan@10.1.14.108:/home/sravan/xyz subin@10.1.14.109:/home/subin
The scp command allows you to copy files over ssh connections. This is pretty useful if you want to transport files between computers, for example to backup something.

1.To copy from a (remote) server to your computer
scp -r [login name@ip address] : [/path/filename] .

Ex : scp -r /home/subin/Desktop/abc sravan@10.1.14.36:.
Ex : scp -r /home/subin/Desktop/abc sravan@10.1.14.36:/home/sravan/Desktop

on clicking enter, it will show all the tasks which are currently in the host
by seeing the PID of the task, we can kill that particular task in the following way
before that you have to come out of the "top", for that press ctrl+c
now enter the following command
[root@wipro-049cafd91 subin]# kill 54789
on clicking enter this will kills the task in the host

Shell in Linux
A shell is a command-line interpreter: it takes commands and executes them.Bash (Bourne-again shell) is the default shell for most current Linux distributions (and Mac OS X) and can be run on most Unix-like operating systems.To check what shell you are currently using, open the console, type echo $SHELL, and press Enter. It should return a pathname ending with /bash.
