NAME

       cpmchattr - change file attributes on CP/M files

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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

       attrib Set the file attributes as given.

FILE ATTRIBUTES

       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
              permissions.

       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.

RETURN VALUE

       Upon successful completion, exit code 0 is returned.

ERRORS

       Any errors are indicated by exit code 1.
