NextCloud: Transfer Ownership

Summary

NextCloud is an open-source self-hosted file share platform forked from ownCloud.

I had to transfer the ownership of shared files/directories due to personnel change the other day.

A simple way was to download all the files and then upload them by the new owner.
But it was too impractical as they were so big.

Alternatively, I carried it out via command lines with occ.
occ is NextCloud's command-line interface to perform server operations whose name is after "o"wn"C"loud (the origin) "C"onsole.

Environment

Tutorial

The command of occ to use is Files' transfer-ownership
The basic format is:

$ occ files:transfer-ownership <from-user> <to-user>

In my environment, occ didn't exist among PATH environment variable.
Therefore, I used find to get the path, and specify it in the command line as <lib-dir-path>/occ.
Additionally, I had to run it with specified PHP.

$ php73 <lib-dir-path>/occ files:transfer-ownership <from-user> <to-user>

Finally, it was required to run as the web user, apache in my case:

$ sudo -u apache php73 <lib-dir-path>/occ files:transfer-ownership <from-user> <to-user>

The output was:

Analysing files of <from-user> ...

Transferring files to <to-user>/files/transferred from <from-user> on 2019-06-12 01-56-02 ...

 19/25 [=====================>------]  76%Share with id 57 points at deleted file, skipping
 20/25 [======================>-----]  80%Share with id 58 points at deleted file, skipping

 22/25 [========================>---]  88%Share with id 61 points at deleted file, skipping
 23/25 [=========================>--]  92%Share with id 87 points at deleted file, skipping
 24/25 [==========================>-]  96%Share with id 88 points at deleted file, skipping
 25/25 [============================] 100%

As a result, a new directory named "transferred from <from-user> on 2019-06-12 01-56-02" (printed in the console) was created in <to-user>'s home and all the files were owned by the new owner there.
All I had to do then was to log in as <to-user> and move them as needed : )
