I encounter a problem

[jie zhang]

hi,
  I wrote two shell scripts,
    while1:while echo -n;do echo  while1;done
    while2:while echo -n;do echo  while2;done
  and a Makefile,like this
          test:
                . while1;\
                . while2
    Then I run 'make -j 2',when I use 'ps -e' to view
active process,I found two 'sh' process.I think I
should only see one 'sh' process,because I use ';' to
split two command.Why I saw two process?
    Thank you very much!
                                        jie
                                             6/7/00
