how to find out 32bit or 64bit binaries

Vimala L — Tue, 10 Sep 2002 08:16:08 GMT

Hello there.

I wish to find out whether an executable is 64bit or 32bit. Can you please help me with the unix commands to find that?

Thank you,
Vimala.

Also tels you about the C compilers and the kernel version/architecture

getconf KERNEL_BITS

Man getconf for more.

cd
file * | grep executable | grep ELF-64

Will show 64 bit binaries. Anything else is only 32 bit (eg. PA-RISC1.1 or PA-RISC2.0)

SivaKumar is correct, use file.

It may/may not obvious in many cases. However the following can be used:
PA-RISC1.1 shared executable dynamically linked = 32 bit
ELF-64 shared object file - PA-RISC 2.0 (LP64) = 64 bit

In most cases if it does not explicitly state 64 bit, it's probably not. Another way to see a bit about how it was compiled is to use chatr. Look for references to 64 bit libaries.
# chatr /usr/bin/login
shared library list:
dynamic /usr/lib/libpam.1
dynamic /usr/lib/libsec.2
dynamic /usr/lib/libnsl.1
dynamic /usr/lib/libc.2

A 64 bit library might be:
/ux/libsobj_i80/libs/libc/shared_pa2_64/obj

Sorry for my misunderstood, Vimala. I read your post very quilcly but obviously I missed something, file is correct.
