10 Examples of using find command in UNIX
find is very versatile UNIX command and I used it a lot in my day to day work. I believe having knowledge of find command in UNIX and understanding of its different usage will increase your productivity a lot in UNIX. If your works involve lots of searching stuff or if you are a java or C++ programmer and your code resides in UNIX, find can greatly help you to look for any word inside your source file in the absence of an IDE, find is the alternative way of searching things in UNIX. Grep is another UNIX command which provides similar functionality like find but in my opinion find is much more powerful than grep in UNIX.
