Get/set Unix file 'owner'?
«
on:
June 17, 2021, 09:12:07 pm »
CudaText runs 'pkexec /bin/cp old_filename new_filename'.
It works OK but the owner of that file changes from 'root' to my name.
Can I change the owner of a file?
Can I read the owner of a file?

To run the 'pkexec --user username' I need the string-user-name of file owner. How to get it?

don't you need elevated rights (sudo) to assign "root" as the owner?

Hi!
Oops - you need it vice versa.
For UserId 1000 you use:
Code: Bash
[Select]
[+]
[-]
grep
-
w
1000
/
etc
/
passwd
It returns in my case:
Code: Text
[Select]
[+]
[-]
winni:x:1000:100::/home/winni:/bin/bash
which is:
Code: Text
[Select]
[+]
[-]
UserName:pwd:UserID:GroupID:comment:HomeDirectory:shell

Thanks.
I found that 'pkexec /bin/mv' does NOT set root owner. But 'pkexec /bin/cp filename /etc/filename' does it! Solved.
