cfind — search in C source files

cfind searches all C source files in a directory and its subdirectories for a given string.

cfind can distiguish some parts of the source code (declarations, preprocessor directives, remarks, parameters, function bodies) and one can restrict the search to some of these. It can also distinguish some compound words and search for whole words or word parts.

cfind is free software under the GNU General Public License.

To search in the current working directory and subdirectories all .c and .h files for functions, variables or macro definitions of the identifier "begin":

cfind begin

To exclude functions such as "begin123" or "begin_" from the matches:

cfind begin --whole-word

These searches will output all declarations, but not the calls to these functions or variables. To see just where they are called:

cfind begin --body

To search for the exact word "begin" in source code comments

cfind begin --rem
