Recursive grep of all c++ source under the current directory

I like this better than some of the alternatives using -exec, because if I want to change the string, it's right there at the end of the command line. That means less editing effort and more time to drink coffee. Show Sample Output

Recursive grep of all c++ source under the current directory

Gnu grep allows to restrict the search to files only matching a given pattern. It also allows to exclude files.

grep -R --include=*.cpp --include=*.h --exclude=*.inl.h "string" .

What Others Think

Hi, Gnu grep allows a more simple syntax: grep -R --include=*.cpp "string" . It does also allows to exclude files and directories

The only real issue with using grep directly with recursion and includes is it doesn't handle "recursive directory loops" very nicely. However, the include and exclude stuff will definitely go into my arsenal. :)
