This file exists, with this ownership and group:
Output of the 'id' command for user picard is:
Output of the 'id' command for user worf is:
When worf runs:
the ownership and group look like:
Both picard and worf belong to starfleet. Even though worf's effective gid isn't "starfleet", worf was expecting to see "starfleet" as the group owner of the mycopy.txt file.
How can worf get the desired results? Is there some other command that should be used instead of 'cp' command to achieve the desired results?
Yes, using "chgrp" to change the group owner works, but is there some single copy-like command (ie: "tar" or "rsync", etc...) that can be used?

Thanks :confused: (1 Reply)

KEYCTL_CHOWN(3) Linux Key Management Calls KEYCTL_CHOWN(3)NAME
keyctl_chown - Change the ownership of a key
SYNOPSIS
#include <keyutils.h>
long keyctl_chown(key_serial_t key, uid_t uid, gid_t gid);
DESCRIPTION
keyctl_chown() changes the user and group ownership details of a key.
A setting of -1 on either uid or gid will cause that setting to be ignored.
A process that does not have the SysAdmin capability may not change a key's UID or set the key's GID to a value that does not match the
process's GID or one of its group list.
The caller must have setattr permission on a key to be able change its ownership.
RETURN VALUE
On success keyctl_chown() returns 0 . On error, the value -1 will be returned and errno will have been set to an appropriate error.
ERRORS
ENOKEY The specified key does not exist.
EKEYEXPIRED
The specified key has expired.
EKEYREVOKED
The specified key has been revoked.
EDQUOT Changing the UID to the one specified would run that UID out of quota.
EACCES The key exists, but does not grant setattr permission to the calling process.
LINKING
This is a library function that can be found in libkeyutils. When linking, -lkeyutils should be specified to the linker.
