I'm running BASH scripts to move files around in an archive.
Of course, they shouldn't run as root - but when I try to preserve permissions/ownership/times for the transferred files, I sometimes run into the problem that e.g. rsync, mv, chmod throw a warning, saying "Operation not permitted"
Here are some example warning messages:
rsync: failed to set times on "xxx": Operation not permitted (1)
mv: preserving times for `xxx': Operation not permitted
mv: preserving permissions for `xxx': Operation not permitted
chmod: changing permissions of `xxx': Operation not permitted
In my case, the files' owner was someone else. I just had read/write access by group rights.
This is not enough to change the timestamp and/or ownership.
When I ran my scripts using "sudo -u USERNAME", where "USERNAME" is the owner of these files, it works correctly.
This applies at least to the following commands:
Code: Select all
$ cp -av $ rsync -a $ mv $ chmod
