This tells you the *kernel* version. Note that for most architectures,
the 64 bit version can run 32 bit applications fine if you make sure to
have the libs installed.

So "the release 'is' 64 bit" or "... 32 bit" is misleading.

Yes BUT <grin>
I have hardware which is 64 bit but at different has been running both
32 and 64 bit Debian. I need to know which was active now.

I've always favored "file /bin/ls" to get the architecture.

hobbit:~$ file /bin/ls
/bin/ls: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=15dfff3239aa7c3b16a71e6b2e3b6e4009dab998, for GNU/Linux 3.2.0, stripped

It's extremely likely that whatever arch /bin/ls uses is the "primary"
arch for the system. It works on every Linux system I've encountered,
even if the kernel doesn't match it.

Of course, for Debian specifically, there's also

dpkg --print-architecture

If that agrees with file /bin/ls, then you've got one more level of trust.

This is an edit/resend. Originally I tried to reconstruct the initial login of the
day, but brain fart got things backwards, after the upgrade and reboot.

I'm sure that if a reader has done the following they would know and
remember, but I do have some i386 Debian hosts which were partially cross-graded to amd64 only as far as running the amd64 kernel while
leaving all of the user land and the primary dpkg architecture as
i386. This is a supported configuration.

In that case "uname -a" reports the amd64 kernel correctly, while
"file /bin/ls" and "dpkg --print-architecture" both still report i386!

😀

Thanks,
Andy

It's not just "supported": it's basically the recommended setup for an
i386 install, since the support for the i386 kernels is being EOL'd.

Others may have noticed me already pointing this out at length in
other threads. 😀

If you start with a system that was installed as i386 it's easy to
just install an amd64 kernel.

Some try to fully cross-grade userland to amd64, e.g.:

https://wiki.debian.org/CrossGradingo

Or by using this script:

https://salsa.debian.org/crossgrading-team/debian-crossgrading/-/blob/master/INSTRUCTIONS.md

However, both of those involve some very hairy steps. It's never
been fully automatic for me and has involved some outcomes that were
tricky to recover from. I wouldn't recommend that a non-expert tries
it. It took longer than just reinstalling.

I have had customers try to do this and end up taking a wrong step,
resulting in a very broken system. Repairing it for them isn't
something they pay me for so I've advised reinstall at that point
also.

So on most of these legacy systems I stopped with just the kernel,
since that's the majority of the benefit anyway.

Thanks,
Andy
