C / C++ in existing Eclipse IDE
Date : Monday, 17th September, 2012
I always love when it comes to Eclipse... Started with Java, I added (from here) support for python (PyDev) in Eclipse. But browsing on google for adding support for C / C++ seemed to suggest downloading of new IDE ( even though it is some version of eclipse, it is not the same installation which we use for Java ).
There is a way to add support for C/C++ within existing installation of Eclipse. You can follow following steps :
Open Eclipse, Go to Help > Install New Software
Click on "Available Software Sites"
Select http://download.eclipse.org/tools/cdt/releases/indigo. NOTE: 'indigo' is my version, for you, this may be different. Hit Ok.
In 'Work with' drop down menu, select http://download.eclipse.org/tools/cdt/releases/indigo
Select whole CDT Main Features
From CDT Optional Features, select both : C/C++ GNU Toolchain {Build|Debug} Support.
Hit Next.
Some procedure from this point onwards will be updated.
CSCOPE Usage

I prefer cscope -CqRv for examining a large project of C files like GCC or linux kernels.
CTAGS Usage
Date : Tuesday, 7th January, 2014
As I use vim editor instead of emacs, I use ctags instead of etags to create tag files for vim. I use "Exuberant Ctags" instead of its GNU version because I found applying ctags recursively for hierarchy of directoris easy in Exuberant Ctags than GNU version. I prefer the command ctags -R *.
UPDATE: Recently I bumped into a problem where a tags file was getting generated properly but vim was not able to find tags when I tried to find a tag from a subdirectory. Basically a fix is to instruct vim to keep looking for tags file up a directory at a time till it reaches root. I found this stackoverflow page useful. I added this line : set tags=tags;~,TAGS;~ to this file : ~/.vimrc . And then ran catgs -R *.

Avoid accidentally deleting everything by wrong usage of linux command rm -rf *.
Date : Tuesday, 5th February, 2013
Create a file with a name "-i" in any directory whose contents you want to prevent from accendental deletion.( for ex. $(HOME)) Create it using "touch -- -i" or "touch ./-i".
Whenever command "rm -rf *" gets executed in the directory, the -i file will be interpreted by rm command as one of the switch! and it will ask :
rm: remove directory `a'? n
rm: remove directory `b'? n
rm: remove directory `c'? n
rm: remove directory `d'? n
Now if you DO WANT to delete all contents in this directory, first remove '-i' file : "rm ./-i" and then, ususal "rm -rf *".
Use cscope utility with *.java files
Date : Tuesday, 12th February, 2013
Found this info from this usefule blog : Link.
In the project root directory, do : find ./ -iname *.java > cscope.files
Then you can use cscope in usual way ( for e.g. cscope -CqRv).
