Linux linux32 Command

What is Linux linux32 Command?

In this tutorial we learn how to use linux32 command in Linux. linux32 command is used to execute a program as if it were running on a 32-bit x86 (i386/i686) Linux environment, even when the host operating system is 64-bit (x86-64).

It facilitates backward compatibility, allowing older 32-bit applications, binaries, or libraries to run on a 64-bit system. It functions by modifying the ‘personality’ of the current process, which adjusts how the Linux kernel interprets system calls and perceives the process’s architecture.

linux32 Syntax

linux32 [command] [arguments...]

linux32 is often a symbolic link or script wrapper for the more general setarch i386 or setarch i686 command, which offers more granular control over execution domain parameters.

For linux32 to successfully execute a program, the 64-bit Linux system must have the necessary 32-bit user-space libraries installed (e.g., libc6-i386 or ia32-libs packages on some distributions). Without these, 32-bit binaries may fail due to missing shared libraries.
