cpmchattr - change file attributes on CP/M files
cpmchattr [-f format] image attrib file-pattern ...
Cpmchattr changes the file attributes for files on CP/M disks.
Use the given CP/M disk format instead of the default format.
attrib Set the file attributes as given.
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
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.
Upon successful completion, exit code 0 is returned.
Any errors are indicated by exit code 1.
