(cache)How to allow everyone to set the last modified time of a file?

exerceo · Today, 10:10 AM

cp -p allows preserving date and time stamps and touch has some parameters to set a custom last modified time (mtime).

But normally, in Linux (and Android by extension), only a file owner can set a custom date and time.

Is there a way to give everyone the ability to set a custom date and time of a file?

I have not used this on Linux, but I have used it on AIX. I believe Linux does have this ability, depending on distro and file system.

I am rather sure there is a way of doing that under Linux. You need to use attributes to give specific users write access to the file. Maybe you can use it to prevent deletion too.
