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.

       -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.

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.

ENVIRONMENT

       CPMTOOLSFMT    Default format
