       cpmchattr - change file attributes on CP/M files


       cpmchattr [-f format] image attrib file-pattern ...


       Cpmchattr changes the file attributes for files on CP/M disks.


       -f format
              Use the given CP/M disk format instead of the default format.

       -T libdsk-type
              libdsk  driver  type, e.g. tele for Teledisk images or raw for raw images (requires
              building cpmtools with support for libdsk).

       attrib Set the file attributes as given.


       The file attribute string can contain the characters 1,2,3,4,r,s,a,n and m.  The  meanings
       of these are:

       1-4    The  CP/M  "user  attributes"  F1-F4.   CP/M  does  not assign any meaning to these
              attributes, though MP/M does.

       r      The file is read-only.  This is the same  as  using  cpmchmod(1)  to  revoke  write

       s      The file is a system file.  This attribute can also be set by cpmchmod(1).

       a      The file has been backed up.

       n      Reset  all  attributes to zero.  So the string "n1r" resets all attributes and then
              sets F1 and Read-Only.

       m      Attributes after an  m  are  unset  rather  than  set.   The  string  "12m34"  sets
              atttributes F1 and F2, and unsets F3 and F4.


       Upon successful completion, exit code 0 is returned.


       Any errors are indicated by exit code 1.
