how to use the unix “find” command to find all the cpp and h files?

Question

I know that to find all the h files I need to use: find . -name "*.h" but how to find all the h AND cpp files?

Answer 1

find . -name \*.h -print -o -name \*.cpp -print

or

find . \( -name \*.h -o -name \*.cpp \) -print

Answer 2

find -name "*.h" -or -name "*.cpp"

(edited to protect the asterisks which were interpreted as formatting)

Answer 3

Paul Tomblin Has Already provided a terrific answer, but I thought I saw a pattern in what you were doing.

Chances are you'll be using find to generate a file list to process with grep one day, and for such task there exists a much more user friendly tool, Ack

Works on any system that supports perl, and searching through all C++ related files in a directory recursively for a given string is as simple as

ack "int\s+foo" --cpp 

"--cpp" by default matches .cpp .cc .cxx .m .hpp .hh .h .hxx files

(It also skips repository dirs by default so wont match on files that happen to look like files in them.)

Answer 4

A short, clear way to do it with find is:

find . -regex '.*\.\(cpp\|h\)'

From the man page for -regex: "This is a match on the whole path, not a search." Hence the need to prefix with .* to match the beginning of the path ./dir1/dir2/... before the filename.

Answer 5

find . -regex ".*\.[cChH]\(pp\)?" -print

This tested fine for me in cygwin.

Answer 6

You can use find in this short form:

find \( -name '*.cpp' -o -name '*.h' \) -print

-print can be omitted. Using -o just between expressions is especially useful when you want to find multiple types of files and do one same job (let's say calculating md5sum).
