I'm studying shell in Linux these days. and I've had one question.

Please, look at below command:

$ find . -name '*.c' -or -name '*.cpp'

Above command is processed like below command internally?

$ find . -name '*.c' -and -print -or -name '*.cpp' -and -print

Read find(1) perhaps by typing man find and read the man page of every command before using it. Some few commands are builtin, e.g. cd. So read also the documentation of your shell, e.g. bash(1)

man find says:

 If the whole expression contains no actions other than -prune or -print,
 -print is performed on all files for which the whole expression is true.

So yes, it's equivalent, but it's probably easier to think of it as:

find . ( -name '*.c' -or -name '*.cpp' ) -and -print

or simpler, and POSIX-compliant:

find . ( -name '*.c' -o -name '*.cpp' ) -print

Basically both commands means same and display same output. Why to do with longer when you have shorter way?

For primitives A = -name '*.c', B = -name '*.cpp', C = -print we have the following equations

Your first example: (A+B).C

Your second example: (A.C)+(B.C)

These have a straightforward mathematical equivalence, ie they are the same. But the first is shorter and more succinct.
