setarch

Change the reported architecture for a program's execution, primarily used to modify how programs behave based on system architecture. Useful for compatibility testing or running legacy applications. More information: https://manned.org/setarch.8.

• Run a command as if the machine architecture is i686 (useful for running 32-bit apps on a 64-bit kernel):

setarch i686 {{command}}

• Run a shell with the x86_64 architecture:

setarch x86_64 {{bash}}

• Disable randomization of the virtual address space:

setarch {{linux32}} {{[-R|--addr-no-randomize]}} {{command}}

• List supported architectures:

setarch --list

• Display help:

setarch {{[-h|--help]}}
