Executing binary file in linux

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 Binary Files in Linux

Binary files or bin files are executable files in the operating system also known as non-text files. These files can contain anything in it like images, compiled files, metadata, chain of sequential bytes or a text file having encoded binary data.

In Linux and Unix-like operating systems, .bin files contain machine code in it and can be executed on the system. All the data encoded in binary files cannot be readable by humans. These files can store anything except text.

How to Execute Binary Files in Linux:

To execute a binary file in a system, all you need to do is work as a super user with all privileges and permissions.

To run binary files on a Linux system, we need to make it executable by accessing them using a terminal. It can be done by following 3 steps.

1. 1. Open the command-line prompt by pressing ctrl+alt+t.
   2. The next step is to run without giving permission.

   

   Now, the file is ready to run on Linux system, again open the terminal and type the command:

   

   In this file doesn’t open and shows permission denied message, use sudo in command and run it again:

   

   Conclusion

   The .bin files are the binary files that contain information to be executed in a system. They are encoded with machine code and cannot be readable. The article has shown how we can make binary files executable by giving them permission. These files cannot be executed without permission access and sudo privileges.

   Execute Binary Files In Linux

   Linux has many format options for running applications from deb to rpm and the new formats snap and flatpak. Binary files can be in .bin or .run formats and although this can be easy to install it can be hard to remove and need an extra trick and a little experience to complete the removal.

   Some of the .bin and .run files need root privileges to install or run the applications. For being able to install the applications you need to run it with sudo command.

   ‘sudo’ Command

   Sudo permits the user to execute a command as a superuser (with higher privileges or root permissions).​

   

   On the example below, you can notice that trying to update using the terminal without root privileges gives you a permission error message.

   Running Binary Types (.bin and .run)

   There are two ways to run binary applications, one is through the user interface and the other is going to the terminal.

   User Interface Option

   To Install using the user interface, first, you need to make the file executable. To make the file executable first, right-click on the binary file and then properties and go to permissions. On Permissions thick the checkbox with the option allows executing the file as program close the program and double click on the binary. If the file doesn’t run, just right-click on it and select run on the terminal to execute it.

   Sometimes when you run the binary it takes a while to execute it if the file size is big. So be patient and wait for it. If it doesn’t try running it from terminal.

   Terminal Option

   To run it through terminal it’s not a hard task either. For being able to run it just make the file executable using chmod +x app-name.bin command and then execute it with ./app-name.bin.
   ​
   Note that if the application doesn’t run with an error message permission denied with normal privileges you may need to use sudo ./app-name.bin​

   

   Conclusion

   Linux has many options for running or installing applications which is one of the good things of Open Source, binary files are just one out there. There are snap packages, Flatpak, deb and many more, some applications are available on these formats so it’s up to choose which one you prefer.

   So what application extension you choose?
