    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.  

    OPTIONS

    -v
    Be verbose.
    -h, --help
    Display help (it is also displayed when setarch takes no arguments).
    -3
    Specifies that processes should use a maximum of 3GB of address space on systems where it is supported (ADDR_LIMIT_3GB).
    -B
    Turns on ADDR_LIMIT_32BIT.
    -F
    Userspace function pointers point to descriptors (turns on FDPIC_FUNCPTRS).
    -I
    Turns on SHORT_INODE.
    -L
    Changes the way virtual memory is allocated (turns on the ADDR_COMPAT_LAYOUT).
    -R
    Disables randomization of the virtual address space (turns on ADDR_NO_RANDOMIZE).
    -S
    Turns on WHOLE_SECONDS.
    -T
    Turns on STICKY_TIMEOUTS.
    -X
    Turns on READ_IMPLIES_EXEC.
    -Z
    Turns on MMAP_PAGE_ZERO.
