Question

I am writing a bash script to deal with some installations in an automated way… I have the possibility of getting one such program in 32 or 64 bit binary… is it possible to detect the machine architecture from bash so I can select the correct binary?

This will be for Ubuntu machines.

Answer 1

Does

uname -a 

give you anything you can use? I don’t have a 64-bit machine to test on.

Note from Mike Stone: This works, though specifically

uname -m 

Will give ‘x86_64’ for 64 bit, and something else for other 32 bit types (in my 32 bit VM, it’s ‘i686’).
