cpmchattr - change file attributes on CP/M files
Contents
Description
Cpmchattr changes the file attributes for files on CP/M disks.
Environment
CPMTOOLSFMT Default format
Errors
Any errors are indicated by exit code 1.
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.
