Do you need to find out if your Linux installation is 32 bit or 64 bit? I usually need this information when manually installing a piece of software (e.g. Netbeans Profiler Remote Pack).
There are two alternative commands which produce identical output. You can use any one of these:
- arch
- uname -m
If any of these commands outputs x86_64 then your Linux is 32 bit. On the other hand, if the output is i686 or i386 then you are running a 64 bit Linux distro.
