Are you sure copyfile.sh doesn't exit until it's done?  How do you know?

Sorry for the confusion. My typo problem

the makefile is like this:
all :
      $(SHELL) ./copyfile.sh
      cd $(OBJ_DIR) && mv foo.o newfoo.o

foo.o is a very large file that copy to $(OBJ_DIR) by
the 'copyfile.sh' script.
While the copy is in progress the 'mv' is executing
cause it to fail becase foo.c is not yet copy to the
$(OBJ_DIR)

Thanks

It always does.

No it doesn't.

I don't see how the fact that the script copies
several large files
tells you anything about when the cd runs.


Remember that the working directory is a function of your current shell, AND that every command make invokes is run in its own shell. So a command like:

       cd $(OBJ_DIR)

is a complete no-op, since as soon as this command
is done the shell
will exit and there goes your working directory
context.
