This doesn't mean that copyfile.sh is not exiting prior to finishing.

because the next statement get executed and it failed because foo.o is not yet get copy.
Now if I modified the makefile to this: all : $(SHELL) ./copyfile.sh then run it.
wait for about 1 minute.... then modify the makefile to this: all : cd $(OBJ_DIR) && mv foo.o newfoo
then run again it work great
Thanks for your help

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.
