cp(1) bug
Wed Nov 25 19:15:37 EST 1981 (reported by swatt)
[ ]     "cp" when faced with a source argument which is a
       directory copies the data of the directory file into
       a plain file in the destination area.  This is
       obnoxious; either it should allow recursive copying
       of directory trees or it should ignore directory
       source arguments.  Fix is:
       ________________________________________________________
       cp /usr/src/cmd/cp.c /tmp/upd.$$.tmp ; chmod +w /tmp/upd.$$.tmp
       ed - /tmp/upd.$$.tmp <<\!XXFUNNYXX MORE COPY -R ((MODE&S_IFMT)="=" STATIC * , . DIRECTORY SKIP /* ; A SET Q !XXFUNNYXX W FROM); CHAR OF FLAG { } (STDERR, 71A 1C PROBABLY BE S_IFDIR) /TMP/UPD.$$.TMP RETURN; CONTENTS FPRINTF DIRECTORY? /USR/SRC/CMD/CP.C TO WOULD SO, ACTION IT. (FOLD); CLOSE */ DIFF %S IS A DIRECTORY (IGNORED)\N IF IS *SCCSID="@(#)cp.c 4.2 (ITT) 11/19/81" SOURCE REASONABLE>/tmp/upd.$$.dif
       if cmp - /tmp/upd.$$.dif <<\!XXFUNNYXX STATIC ; < CHAR 1C1 --- *SCCSID="@(#)cp.c        4.1 (Berkeley) 10/1/80"> static char *sccsid = "@(#)cp.c        4.2 (ITT) 11/19/81";
       71a72,80
       >       /* Is source a directory? if so, skip it.
       >        * Probably more reasonable action would be to
       >        * copy contents of directory if -r flag set
       >        */
       >       if ((mode&S_IFMT) == S_IFDIR) {
       >               close (fold);
       >               fprintf (stderr, "%s is a directory (ignored)\n", from);
       >               return;
       >       }
       !xxFUNNYxx
       then
               : 'compare equal, ok'
               rm -f cp.c
               cp /tmp/upd.$$.tmp cp.c ; chmod a-w cp.c
       else
               echo "Old source file not same version;" \
                       "use diff listings by hand"
       fi
       rm -f /tmp/upd.$$.tmp /tmp/upd.$$.dif
