NAME
setarch - change reported architecture in new program environment and/or set personality flags
SYNOPSIS
setarch [arch] [options] [program [argument...]]
setarch--list|-h|-V
arch [options] [program [argument...]]
DESCRIPTION
setarch modifies execution domains and process personality flags.
The execution domains currently only affects the output of uname -m. For example, on an AMD64 system, running setarch i386program will cause program to see i686 instead of x86_64 as the machine type. It can also be used to set various personality options. The default program is /bin/sh.
Since version 2.33 the arch command line argument is optional and setarch may be used to change personality flags (ADDR_LIMIT_*, SHORT_INODE, etc) without modification of the execution domain.
