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.
- -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).
- 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:
- The CP/M "user attributes" F1-F4. CP/M does not assign any meaning to these attributes, though MP/M does.
- The file is read-only. This is the same as using cpmchmod(1) to revoke write permissions.
- The file is a system file. This attribute can also be set by cpmchmod(1).
- The file has been backed up.
- Reset all attributes to zero. So the string "n1r" resets all attributes and then sets F1 and Read-Only.
- 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.
