There is also the very real possibility, however slight, that you might instead come across a binary that when you attempt to run it spews out junk characters to the terminal even if you’ve run a malware scan on it. If you’re on a 64-bit microprocessor running 32-bit Ubuntu, then you could technically reinstall the operating system, though this is a bit of an extreme step in order to run a single program. ![]() If it tells you that it’s an ELF 64-bit binary and you received i686 as output from the arch command, then there’s no way you can reasonably run it on your machine. Try identifying the file in question by typing file nameOfProgram to see if you get ELF 32-bit or ELF 64-bit as output. The file command identifies what different files contain, and it’s usually very accurate. That doesn’t mean that Ubuntu doesn’t work on these machines, though you may want to look at the lighter Lubuntu distribution. However, you more than likely won’t be able to run many Linux binaries you download from the Internet outside of the official repositories in this case. You can actually still find Ubuntu repositories for these architectures, though they receive little support today. Ubuntu supported PowerPC architecture for the longest time, which is found in some workstations as well as many Classic Macintosh and older OS X Macintosh machines. You may see some other types of output, which might further restrict your options when it comes to running software. Users of a virtual console, especially those working with Ubuntu server, won’t have to worry quite as much. Since the lines in this file are long, you might want to push F11 before issuing it if you’re using a graphical terminal window. You can use cat /proc/cpuinfo or more /proc/cpuinfo to find out the exact type of processor you’re using. This doesn’t indicate an error, and can be safely ignored. Even if you’re using 64-bit Intel technology, arch might still call your processor an amd64 chip. For instance, i686 is how Linux refers to many 32-bit processors even if they aren’t actually Intel 80686 chips. These terms are still true even if you’re not actually using that particular model of microchip. Unlike Microsoft Windows, Ubuntu Linux actually contains the proper tools to permit users of 644-bit chipsets to run 16-bit Windows programs in their operating system in many cases as well. If you instead see amd64 or something similar, then you’re on an x86_64 processor, and should at least theoretically be able to run most 32-bit and 64-bit binaries. In many cases, you’ll see i686, which means that you’re on a 32-bit processor and therefore can’t run x86_64 binaries. You’ll only see a single line of output returned to you after running this command. If you’re not familiar with the type of microprocessor that you have installed on your machine, then you’ll first want to use the arch command from the command line. A few simple commands are all it takes to tell what your chip is operating as. It’s important to remember that 64-bit processors can run in 32-bit mode, so if you’re getting this error even though you have a 64-bit processor there’s a chance you’re running a 32-bit version of Ubuntu. Most people using Ubuntu are on 32-bit or 64-bit processors based around a standard architecture that Intel released, regardless of who actually made their microchips. This is because while it’s apparently a valid Linux binary, it’s designed for a different chipset than your kernel currently supports. nameOfProgram.sh: Permission denied or something like it, indicates that Ubuntu wasn’t able to interface correctly with the binary you downloaded. This error, which is usually followed by bash. nameOfProgram: cannot execute binary file: Exec format error. While it shouldn’t happen when using the official apt-get repositories, if you download software off the Internet and run it then there’s a chance that you’ll see the dreaded bash. ![]()
