In addition to the package name, also note that only rxstat uses an M prefix; all others use S.
+- Assuming you have a fairly modern grep, you can use its recursive facility:
+
+ $ **grep -r regex .**
+
+and find every time <pattern> appears in a file
+
+- If you're looking for one specific word, the <tt>-w</tt> switch is your friend as well.
+
+ $ **egrep -w -r VFORMAT .**
+
+will find all instances of **VFORMAT** but will not find **ABVFORMAT**

- cscope: a source code browser, linked to your editor. Setup is simple: cd to your source tree and run:
- cscope -R -b
+ $ **cscope -R -b**
Then run
- cscope -d
+ $ **cscope -d**
to start. The interface is simple. I tend to use it for finding things, but not necessarily for editing. When I'm studying the source, trying to understand how components link together, or bug-hunting, I tend to live inside `cscope`.
