       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.

       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.
