I added echo command in both files. Then i open new terminal it shows both echo commands. first shows the etc echo command and then shows the other echo commands. that means bashrc in the etc folder runs 1st.

I found that there are two kind of bashrc files in the linux folder stucture. one is located in etc/bashrc. Other one is located in Home/username/.bashrc.

1) What is the difference purpose of these two files ?
2) are both using for setting envirnment variables?

I have updated java in root/.bashrc file as below



So when i login as root user and type echo $JAVA_HOME it shows the java home value. But when i login as any other user it shows empty value. So that means .bashrc file related to user wise. is it true ?

/home/aruna/

thanks Henry, Campbell  and Tim. I just need to finalized below thing.
there are three file .profiles, .bash_profile  and .bashrc . As for my knowledge below is the details of these iles.

1)  .profiles          =  set system wide environmental variables. Executed only for interactive shell. read by many shells
2)  .bash_profile   =  is executed for both interactive and non-interactive shells .
3)  .bashrc           = . only for bash

i need to if we set up same envirment vriable in both .profile and .bashrc what will happen. For example as below
in .profiles    JAVA_HOME = java 1.6
in .bashrc    JAVA_HOME  = java 1.7          

so what JAVA_HOME will take when we open a ssh?

OpenJDK 64-Bit Server VM (build xxxxxxxxx, mixed mode)

I found that Postgress Db has json column implemented. Why relational Db need a json column?
actually i need to get the value from each callback. for example i have a list which contain 10 items. So that means there will be 10 call backs. So each call back i need to access the list and get relevant  value. For example for the 1st iteration  i need to get 1st value of list, but when callback comes the i value of iteration may changed to different value. So how do i know 1st iteration callback comes which items to get from the list?

I am calling Rest API using AsyncRestTemplate inside a loop. Once callback returns i need to access main thread values. But the issue is i am calling AsyncRestTemplate inside a loop as below .




inside callback i need t oaccess list values. but issue is since this runs  inside a loop when callback comes loop may in a different iteration. So how can i access the same values when i am calling exchange methos ?
