64bit or 32bit

[Mazen Jarrah]

Hello everyone,

how can I know if the system I'm using is 64bit or 32bit

You can know it by using,

getconf HW_CPU_SUPP_BITS

It will give that information to you.

Try:
$ getconf KERNEL_BITS

You can known with system configuration with c program as,

#include
main()
{

long ret = sysconf(_SC_HW_32_64_CAPABLE);

if (_SYSTEM_SUPPORTS_ILP32OS(ret) != 0) {
printf ("System supports 32-bit OS");
}

if (_SYSTEM_SUPPORTS_LP64OS(ret) != 0) {
printf ("System supports 64-bit OS\n");
}

}

It will give you the details there.

HTH.
