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.
