13

15       -f format
16              Use the given CP/M disk format instead of the default format.
17
18       -T libdsk-type
19              libdsk driver type, e.g. tele for Teledisk images or raw for raw
20              images (requires building cpmtools with support for libdsk).

25

FILE ATTRIBUTES

27       The file attribute string can contain  the  characters  1,2,3,4,r,s,a,n
28       and m.  The meanings of these are:
29
30       1-4    The  CP/M  "user  attributes"  F1-F4.   CP/M does not assign any
31              meaning to these attributes, though MP/M does.
32
33       r      The file is read-only.  This is the same as using cpmchmod(1) to
34              revoke write permissions.
35
36       s      The  file  is  a system file.  This attribute can also be set by
37              cpmchmod(1).
38
39       a      The file has been backed up.
40
41       n      Reset all attributes to zero.  So the string  "n1r"  resets  all
42              attributes and then sets F1 and Read-Only.
43
44       m      Attributes  after  an  m  are unset rather than set.  The string
45              "12m34" sets atttributes F1 and F2, and unsets F3 and F4.
46
