CPMCHATTR(1)

NAME
cpmchattr - change file attributes on CP/M files

SYNOPSIS
cpmchattr [-f format] [-u] 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).

-u  Show all CP/M file names in upper case.

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/pkg/share/cpmtools/diskdefs    CP/M disk format definitions
