.SH DESCRIPTION \"{{{
\fBCpmchattr\fP changes the file attributes for files on CP/M disks.
.\"}}}
.SH OPTIONS \"{{{
.IP "\fB\-f\fP \fIformat\fP"
Use the given CP/M disk \fIformat\fP instead of the default format.
.IP "\fIattrib\fP"
Set the file attributes as given.
.\"}}}
.SH "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:
.TP
.B 1-4
The CP/M "user attributes" F1-F4.  CP/M does not assign any
meaning to these attributes, though MP/M does.
.TP
.B r
The file is read-only.  This is the same as using
.I cpmchmod(1)
to revoke write permissions.
.TP
.B s
The file is a system file.  This attribute can also be set by
.I cpmchmod(1).
.TP
.B a
The file has been backed up.
.TP
.B n
Reset all attributes to zero.  So the string "n1r" resets all attributes and
then sets F1 and Read-Only.
.TP
.B m
Attributes after an m are unset rather than set.  The string "12m34" sets
atttributes F1 and F2, and unsets F3 and F4.
