Annotation of 42BSD/usr.lib/learn/files/L13.1g, revision 1.1.1.1

1.1       root        1: #print
                      2: Suppose that we really do want to interchange the contents
                      3: of the files "dick" and "jane". One way to do it is
                      4: to move the contents of "dick" into some temporary file,
                      5: then move "jane" onto "dick" (which of course clobbers
                      6: the old contents of "dick", but we saved them already),
                      7: then finally to move the temporary copy of "dick" to
                      8: "jane". There are two files named "dick" and "jane" in this
                      9: directory. Interchange their contents, then type "ready".
                     10: #create Ref
                     11: short file for dick
                     12: #create dick
                     13: short file for dick
                     14: #create jane
                     15: another file for jane
                     16: #create Ref1
                     17: another file for jane
                     18: #user
                     19: cmp -s jane Ref || cmp -s dick Ref1
                     20: #log
