NAME
cpmchattr - change file attributes on CP/M files
SYNOPSIS
cpmchattr [-f format] 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.
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.
