CPMCHATTR(1) User commands CPMCHATTR(1) NAME cpmchattr - change file attributes on CP/M files SYNOPSIS cpmchattr [-f format] [-u] 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). -u Show all CP/M file names in upper case. 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.
