CPMCHATTR(1) User commands CPMCHATTR(1)NAMEcpmchattr - change file attributes on CP/M files
SYNOPSIScpmchattr [-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.
-T libdsk-type
libdsk driver type, e.g. tele for Teledisk images or raw for raw
images (requires building cpmtools with support for libdsk).
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.
