try using the dot command in sh or source in csh:

For sh:
   . file # the current shell reads file and runs it,
	  # file need not be executable

For csh:
   source file # current shell read and runs file,
	       # also does not need execut permissions

In sh (maybe also csh, I do not know), if you are running as root and
the root path does not inlcude the current directory (which is good
security practice), you will need to use the dot command as follows:

   . ./file # provides a relative path pointed at the file
