I don't know what have I done in my Ubuntu 12.04. But whenever I
igarcia@dulx0004:~$ source .bashrc
I get the following
[NS=:]igarcia@dulx0004:~$
What is going on?
source .bashrc
is used to reload your bashrc file without logging out and back in
The error raised is probably of wrong typo in your bashrc file so please check the syntax of your .bashrc file
gedit ~/.bashrc
