How to run binary file in Linux

I have a file called commanKT and want to run it in a Linux terminal. Can someone help by giving the command to run this file? I tried ./commonRT but I’m getting the error:

"bash: ./commonrt: cannot execute binary file" [blackberry@BuildMc MainApp]$ ls -al commonKT -rwxrwxr-x. 1 sijith sijith 10314053 Feb 27 16:49 commonKT

Assuming the problem isn’t just a mixup over names ( commonrt vs commonKT ), what does the command file commonKT /bin/sh say? If it gives two different architectures (perhaps one for ARM and one for Intel), then that’s why you can’t run the ARM one on an Intel machine.

In addition of using file , I also suggest using ldd ; perhaps the dynamic linker or some core shared library is different or missing.

Why does this question have so many upvotes? It contains so many variants of the questioned filename (commonrt, commonKT, commanKT, commonRT), that it’s not even clear what was asked. Also interesting: Does the last comment of Sijith mean that it is answered? And why did user1978011 receive bountys?

To execute a binary, use: ./binary_name .

bash: ./binary_name: cannot execute binary file

it’ll be because it was compiled using a tool chain that was for a different target to that which you’re attempting to run the binary on.

For example, if you compile ‘binary_name.c’ with arm-none-linux-gnueabi-gcc and try run the generated binary on an x86 machine, you will get the aforementioned error.

To execute a binary or .run file in Linux from the shell, use the dot forward slash friend

and if it fails say because of permissions, you could try this before executing it

 chmod +x binary_file_name # then execute it ./binary_file_name

The volume it’s on is mounted noexec .

🙂 If not typo, why are you using ./commonRT instead of ./commonKT ??

It is possible that you compiled your binary with incompatible architecture settings on your build host vs. your execution host. Can you please have a look at the enabled target settings via

on your build host? In particular, the COLLECT_GCC_OPTIONS variable may give you valuable debug info. Then have a look at the CPU capabilities on your execution host via

cat /proc/cpuinfo | grep -m1 flags

Look out for mismatches such as -msse4.2 [enabled] on your build host but a missing sse4_2 flag in the CPU capabilities.

If that doesn’t help, please provide the output of ldd commonKT on both build and execution host.

@craq I see that you gave me your bounty, thanks! Can you please give some info what the error was about?

This is an answer to @craq :

I just compiled the file from C source and set it to be executable with chmod. There were no warning or error messages from gcc.

I’m a bit surprised that you had to ‘set it to executable’ — my gcc always sets the executable flag itself. This suggests to me that gcc didn’t expect this to be the final executable file, or that it didn’t expect it to be executable on this system.

Now I’ve tried to just create the object file, like so:

$ gcc -c -o hello hello.c $ chmod +x hello

( hello.c is a typical «Hello World» program.) But my error message is a bit different:

$ ./hello bash: ./hello: cannot execute binary file: Exec format error`

On the other hand, this way, the output of the file command is identical to yours:

$ file hello hello: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped

Whereas if I compile correctly, its output is much longer.

$ gcc -o hello hello.c $ file hello hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=131bb123a67dd3089d23d5aaaa65a79c4c6a0ef7, not stripped

What I am saying is: I suspect it has something to do with the way you compile and link your code. Maybe you can shed some light on how you do that?

How to Execute .RUN Files in Linux

wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. To create this article, volunteer authors worked to edit and improve it over time.

This article has been viewed 54,491 times.

.RUN files usually contain program data and installation instructions for Linux programs. This wikiHow teaches you how to execute .RUN files in Linux using the Ubuntu terminal. Since RUN files install software, make sure it’s legitimate and won’t harm your computer before executing it. RUN files from suspicious links can contain malware and damage your computer.

Press Ctrl + Alt + T to open a Terminal window and navigate to the folder where your .RUN file is. You can also search for Terminal in the «dash» bar on the left side of your screen by clicking the «All Applications» icon.

If you get a «Permission denied» error during this process, add » sudo » to the beginning of the code so it will run with the appropriate permissions. [1] X Research source

Most Linux distributions have a graphical user interface that allows you to open programs by just clicking on the program’s icon in the Apps menu. However, there are situations where you may want to run a program from the Terminal. The Terminal is a powerful tool that allows you to run programs and manage your Linux system using keyboard commands. This wikiHow teaches you how to run a program from the Terminal in Linux.

Running a Program From the Terminal

Press Ctrl + Alt + T to open the Terminal. You can open the Terminal using the keyboard shortcut on most Linux distributions. The keyboard shortcut is Ctrl + Alt + T. You can also click the Terminal icon in your Apps menu. It generally has an icon that resembles a black screen with a white text cursor.

For example, if you want to run Firefox from the Terminal, you would simply type firefox and press Enter.
Type -h or —help after the program name to display the help menu for that program. Many programs have additional command modifiers you can use to launch the program in a specific way. For example, you can launch a website in a web browser by typing the web browser name followed by the web address and press Enter to launch that website in the web browser (i.e. firefox www.wikihow.com .
If you receive a message that says you don’t have permission to run a program or access is denied, type sudo before the program name and press Enter. The «sudo» command allows regular users to run Terminal commands with administrative privileges or root access.
If you want to run a C or C++ program from the Terminal, you will first need to complie the program before you can launch it from the Terminal.

Running a Program Outside the $PATH Variable

Press Ctrl + Alt + T to open the Terminal. You can open the Terminal using the keyboard shortcut on most Linux distributions. The keyboard shortcut is Ctrl + Alt + T. You can also click the Terminal icon in your Apps menu. It generally has an icon that resembles a black screen with a white text cursor.

Type cd followed by a space and the location the program file is saved to. If the program launch file is saved to a location that is not in your $PATH variable, then you will need to navigate to that location inside the Terminal. You can do so using the «cd» command. For example, if you have folder for Python programs saved in your «Documents» folder, you can navigate to it in the Terminal by typing cd ~/Documents/Python or something similar, and then press Enter.

Type chmod a+x [filename] and press ↵ Enter . Replace «filename» with the actual launch file of the program. The «chmod a+x» command tells Linux the file is an executable file. [1] X Research source

Type «./» followed by the launch filename and press ↵ Enter . This launches the program. For example, if you have a Python file called «Helloworld.py», you would type ./helloworld.py to launch the file. [2] X Research source

Adding a Directory to your $PATH Variable

Press Ctrl + Alt + T to open the Terminal. If you cannot run a program by simply typing the program’s name, you may need to add the directory that the program is installed in to your $PATH variable. You can do this from the Terminal as well. Use the keyboard shortcut to open the Terminal if you haven’t already done so.

For example, if you have a program installed in the «bin» directory of your «Home» folder, you would type export PATH=$PATH:$Home/bin and press Enter. This will temporarily add the «$Home/bin» directory to your $PATH variable.
You can see which directories are currently added to your $PATH variable by typing the command echo $PATH and pressing Enter.

Type nano ~/.bashrc and press ↵ Enter . This opens the «.bashrc» file in a text editor that is based in the Terminal. You can use this file to permanently add the directory to your $PATH variable.

Add the «export PATH» command to the file. To do so, scroll down to the bottom of the file using the mouse wheel and type export PATH=$PATH:[path/to/program] at the bottom. Replace «[path/to/program]» with the actual directory tree the program is installed in. [3] X Research source

Press Y and press ↵ Enter . This confirms that you want to save and exit the text editor. You will be returned to the standard command prompt in the Terminal.

Type source ~/.bashrc and press ↵ Enter . This loads the updated $PATH variable into your current session. [4] X Research source

Type the name of the program and press ↵ Enter . With the program’s directory now added to your $PATH variable, you should be able to launch the program by simply typing the program name and pressing Enter.

Installing and Uninstalling a Program in the Terminal

Press Ctrl + Alt + T to open the Terminal. In addition to launching programs from within the Terminal, you can also install and uninstall programs from within the Terminal. Use the keyboard shortcut to open the Terminal if you haven’t already done so.

Type sudo apt install [app_name] and press ↵ Enter (Debian). Replace «[app_name]» with the actual name of the program you want to install. This command works in Debian-based Linux distributions, such as Ubuntu, and Mint.

Type sudo apt remove [app_name] and press ↵ Enter (Debian). Replace «[app_name]» with the name of the app you want to uninstall. This command works in Debian-based Linux distributions, such as Ubuntu, and Mint.

Type sudo dnf install [app_name] and press ↵ Enter (Red Hat). Replace «[app_name]» with the actual name of the program you want to install. This command works for Red Hat Linux distributions such as RHEL, Fedora, and CentOS.

Type sudo dnf remove [app_name] and press ↵ Enter (Red Hat). Replace «[app_name]» with the name of the app you want to uninstall. This command works for Red Hat Linux distributions such as RHEL, Fedora, and CentOS. [5] X Research source

Type the name of the program and press ↵ Enter . Once the program is installed, you can launch the program by simply typing the program’s name and pressing Enter in the Terminal.
