SETARCH(8)						       System Administration							SETARCH(8)

NAME
setarch - change reported architecture in new program environment and set personality flags SYNOPSIS
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
-v, --verbose Be verbose. -h, --help Display help (it is also displayed when setarch takes no arguments). --uname-2.6 Causes the program to see a kernel version number beginning with 2.6. -3, --3gb Specifies that processes should use a maximum of 3GB of address space on systems where it is supported (ADDR_LIMIT_3GB). -B, --32bit Turns on ADDR_LIMIT_32BIT. -F, --fdpic-funcptrs Userspace function pointers point to descriptors (turns on FDPIC_FUNCPTRS). -I, --short-inode Turns on SHORT_INODE. -L, --addr-compat-layout Changes the way virtual memory is allocated (turns on the ADDR_COMPAT_LAYOUT). -R, --addr-no-randomize Disables randomization of the virtual address space (turns on ADDR_NO_RANDOMIZE). -S, --whole-seconds Turns on WHOLE_SECONDS. -T, --sticky-timeouts Turns on STICKY_TIMEOUTS. -X --read-implies-exec Turns on READ_IMPLIES_EXEC. -Z, mmap-page-zero Turns on MMAP_PAGE_ZERO. EXAMPLES
setarch ppc32 rpmbuild --target=ppc --rebuild foo.src.rpm setarch ppc32 -v -vL3 rpmbuild --target=ppc --rebuild bar.src.rpm setarch ppc32 --32bit rpmbuild --target=ppc --rebuild foo.src.rpm AUTHOR
Elliot Lee <sopwith@redhat.com> Jindrich Novy <jnovy@redhat.com> AVAILABILITY
The setarch command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. util-linux June 2007 SETARCH(8)
