| Issue |
When attempting to copy a file, we get the following error:
Can't change file time (date copied) <filename>: Operation not permitted.
What does this mean?
|
| Solution |
This error means that the copy worked, but 'cp' was unable to modify the file time of the destination to match that of the source. Typically this occurs because the destination file already existed, was not owned by the user (although the user had write permission), and the user is not running as root. If the user owned the desination, ran as root, or were copying to a new destination file (thus owned the destination), 'cp' would be able to duplicate the file time. |
