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

FILES
       /usr/local/share/cpmtools2/diskdefs     CP/M disk format definitions
