NAME
setarch - change reported architecture in new program environment and set personality flagsSYNOPSIS
setarch <arch> [options] [program [arguments]]arch [options] [program [arguments]]
DESCRIPTION
setarch This utility currently only affects the output of uname -m. For example, on an AMD64 system, running 'setarch i386 program' will cause 'program' to see i686 (or other relevant arch) instead of x86_64 as machine type. It also allows to set various personality options. The default program is /bin/sh.OPTIONS

- -h, --help
- Display help (it is also displayed when setarch takes no arguments).
- -3, --3gb
- Specifies that processes should use a maximum of 3GB of address space on systems where it is supported (ADDR_LIMIT_3GB).
