How to find the bit depth of ubuntu?

Question

linux

How can you find out what bit depth was installed if only the data copied from the hard disk remained?

Answer 1

Look:
1 in the /boot folder - the names of the kernels, if there is something like vmlinuz-3.2.0-4-amd64 then this is a 64bit system
2 also on 32bit systems there will be no /lib64 folder in the root

Answer 2

uname -aorarch

Answer 3

what bit depth was set

Kernel bitness -- grep CONFIG_64BIT /boot/config*
Userspace bitness -- by availability /lib64

Answer 4

/etc/os-release contains information about the installed system (sometimes the file is called SuSE-release for example)

Answer 5

Determining the bit depth of Linux by kernel is a stupid idea, the kernel can be 64-bit and run a 32-bit system under itself without any problems (there can no longer be the opposite).
It's easiest to define something like this:
file /bin/bash
