cpmchattr - Man Page

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.
