cpmchattr - change file attributes on CP/M files
cpmchattr [-f format] [-u] image attrib file-pattern ...
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).
-u |
Show all CP/M file names in upper case. |
|||
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 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. |
Upon successful completion, exit code 0 is returned.
Any errors are indicated by exit code 1.
