I have a Dell Latitude E6410 running Debian 9.13

Having a "senior moment" ;{
How do I identify whether in 32 or 64 bit mode.

what does:

# uname -a

say?

mine says:

Linux entwife 7.1.13+deb14-amd64 #1 SMP PREEMPT_DYNAMIC Debian 7.1.13-1 (2026-09-03) x86_64 GNU/Linux


# dpkg -l | grep linux-image

might also add some clues

mine says:

ii linux-image-7.1.12+deb14-amd64 7.1.12-1 amd64 Linux 7.1.12 for 64-bit PCs
ii linux-image-7.1.13+deb14-amd64 7.1.13-1 amd64 Linux 7.1.13 for 64-bit PCs
ii linux-image-amd64 7.1.13-1 amd64 Linux for 64-bit PCs (meta-package)


look at your i386 packages, mine says:

# dpkg -l | grep i386

ii libc6-dev-i386 2.43-5 amd64 GNU C Library: 32-bit development libraries for AMD64
ii libc6-i386 2.43-5 amd64 GNU C Library: 32-bit shared libraries for AMD64
ii libc6-i386-x32-cross 2.43-3cross8 all GNU C Library: 32-bit shared libraries for AMD64 (for cross-compiling)

if i were running a i386 oriented system there would be a lot more than those three.



and then there is the command line in your boot process or grub
and any flags you are passing to that:

mine look like (in Refind):

menuentry Linux-Default-Debian-Testing {
latest-kernel
ostype Linux
volume ROOT_03
loader /vmlinuz
initrd /initrd.img
options "ro root=LABEL=ROOT_03 net.ifnames=0 systemd.dump_core=true"
}

and for grub it looks like: (i normally don't boot using grub)

echo 'Loading Linux 7.1.13+deb14-amd64 ...'
linux /boot/vmlinuz-7.1.13+deb14-amd64 root=/dev/sda2 ro net.ifnames=0
echo 'Loading initial ramdisk ...'
initrd /boot/initrd.img-7.1.13+deb14-amd64

The installed OS:

uname -m

i686 (or anthing like ix86) indicates 32 bit, if it is x86_64, it is 64 bit.

The CPU:
lscpu |grep -i mode
