os9 copy: add option to set file attributes during copy#60
Merged
Conversation
This change adds a new -a option to the os9 copy command that allows OS-9 file attributes to be set as part of the copy operation. The attribute string uses the same syntax as the existing os9 attr command, allowing owner and public permissions to be set or cleared during the copy. Attributes are applied only after a successful copy, so existing behavior is unchanged when -a is not specified. Examples: os9 copy -a=erpepr source dest Copies source to dest and sets owner read/execute and public read/execute permissions on the destination file. This is particularly useful when installing executables, where the desired permissions can now be applied in a single step instead of requiring a separate attr command afterward.
