Open bin files in linux

How to view a binary file?

From what I understand, a compiler makes a binary file that consists of 1’s and 0’s that a CPU can read. I have a binary file but how do I open it to see the 1’s and 0’s that are there? A text editor says it can’t open it. P.S. I have an assembly compiled binary that should be plain binary code of 1’s and 0’s?

no — OP specified «assembly compiled binary». That does not address the question. For instance, it’s not a music file, and it has structure. Without OP providing additional information, an unstructured tool is the place to start.

See my answer. And be warned that the term binary is used in two ways totally different in practice : «A binary file» means a file whose context is not pure ASCII-text. «A binary number» means a number written using its binary form.

You’re not going to get what you’re asking for. On a hard drive, the file is represented by magnetic changes. When the file is read, it’s turned into electrical pulses, which in turn are turned into binary by the processor. Binary itself is only a representation of a number as stated in the answers below. These numbers are then interpreted by the individual programs as the format expected by them, whether this is text or images or something different. You won’t see 1s and 0s by opening a binary file in nano.

unless you want to edit it of course. Most Linux distros have hexdump by default (but obviously not all).

Update

xxd does both binary and hexadecimal

For bin :

Various people have answered some aspects of the query, but not all.

All files on computers are stored as 1’s and 0’s. Images, text files, music, executable applications, object files, etc.

They are all 0’s and 1’s. The only difference is that they are interpreted differently depending upon what opens them.

When you view a text file using cat , the executable ( cat in this case) reads all the 1’s and 0’s and it presents them to you by converting them into characters from your relevant alphabet or language.

When you view a file using an image viewer, it takes all the 1’s and 0’s and turns them into an image, depending on the format of the file and some logic to work it all out.

Compiled binary files are no different, they are stored as 1’s and 0’s.

arzyfex’s answer gives you the tools to view those files in different ways, but reading a file as binary works for any file on a computer, as does viewing it as octal, or hex, or indeed ASCII, it just might not make sense in each of those formats.

If you want to understand what an executable binary file does, you need to view it in a way which shows you the assembler language (as a start), which you can do using,

which is a disassembler, it takes the binary content and converts it back into assembler (which is a very low level programming language). objdump is not always installed by default, so may need to be installed depending on your Linux environment.

NB: as @Wildcard points out, it’s important to note the files don’t contain the characters 1 and 0 (as you see them on the screen), they contain actual numeric data, individual bits of information which are either on (1) or off (0). Even that description is only an approximation of the truth. They key point is that if you do find a viewer which shows you the 1’s and 0’s, even that is still interpreting the data from the file and then showing you the ASCII characters for 0 and 1. The data is stored in a binary format (see the Binary number link above). Pierre-Olivier’s community wiki entry covers this in more detail.

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.

   How to Execute .bin and .run Files in Ubuntu

   

   

   Before we explain how to run .bin and .run files on your Ubuntu system, let’s first define what exactly these file extensions are:

   Bin file: A binary or BIN file in Ubuntu refers to installation packages, which are mostly self-extracting executable files used to install software on your system. You can install most software packages through the Ubuntu Software Manager, such as .deb packages and .tar.xz packages. However, there is software that is not available in these formats. This mainly includes newer software and newer versions of software, usually beta versions, that are not otherwise available. The bin packages are simply run from the Ubuntu command line, the terminal.

   Run File: These are also executable files typically used to install Linux programs. Run Files contain program data and instructions for installation; they are often used for distributing device drivers and software applications. Run packages are easily executed from the Ubuntu command line, the terminal.

   In this article, we will explain how to run/execute the files with .run and .bin extensions on Ubuntu Linux.

   We have run the commands and procedures mentioned in this article on an Ubuntu 22.04 LTS system. We will use the Ubuntu command line, the terminal, to explain how to run bin and run files. You can open the terminal application either by searching in the system application launcher or by pressing Ctrl+Alt+T.

   Note: Make sure that your .run and .bin files are from a reliable source, because running an unsafe file can damage your system and even compromise your system security.

   Executing .bin and .run files

   The process of running both the run and BIN files is pretty simple and straightforward in Ubuntu.

   We are assuming that you have already downloaded your bin/run file in a known location on your Ubuntu.

   Open the Terminal application and move to the location where you have saved the executable file.

   For example, I would use the following command to move to my Downloads folder:

   

   Now use the following command to make your .bin/.run file executable:

   In this example, I will be making a sample .run file named samplefile.run executable.

   If your .run/.bin file does not exist in the current location, you can specify the exact file path/location in the above commands.

   

   My file is now marked as executable. The system indicates it by a change in color of the filename when listed through the ls command:

   

   Once your .bin/.run file has become executable, you can use the following command to execute/run it:

   You can specify the path of the executable file in the above command if it does not exist in the current folder you are in.

   

   My sample file is pretty much an empty file. In the case of a proper installation package, the installation process will begin after you execute the file.

   This is the power of the Ubuntu command line. You can install rare software packages available in the .run and .bin formats easily on your system.

   how to open .bin file using terminal in linux

   I have one .bin file.in that file some data which is important for me and and i want to open that file by using terminal so please help me.I have not any software for that. so give me and command.

   .bin files or .run files are usually, in my experience, self extracting shell scripts. Where did you get this from? What’s the name? What is it supposed to contain?

   do you want to open (read) it or run it? call file my.bin , see if its a shell script and then run it with sh my.bin . i hope the source of the file is trustworthy!

   You have to be sure of what you’re downloading (because a .bin file extension is also used for CD/DVD images and backups). Check with the «provider» (Web Page, CD/DVD instructions, etc. ) of the file that it can be executed as a program.

   A binary file is a computer file that is not a text file. The term «binary file» is often used as a term meaning «non-text file». Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text, such as older Microsoft Word document files, contain the text of the document but also contain formatting information in binary form.

   1. Open your terminal and go to ~$ cd /Downloads (where ~/Downloads is the folder where you bin file is)
   2. Give it execution permissions (just in case it doesn’t have it already):
      ~/Downloads$ sudo chmod +x filename.bin
   3. Write: ./ followed by the name and extension of your bin file. In this example it would be: ~/Downloads$ ./filename.bin
   • If filename.bin needs administrator priviledges to be executed (like an installer would), write ~/Downloads$ sudo ./filename.bin and type your password.
   • ~/Downloads folder is only an example. You can place your bin file anywhere you feel comfortable (yes, even a USB Drive or a SDCard).

   Run Binary Files on Linux

   

   This tutorial intends to teach you to Run or Execute Binary (.bin) Files on Linux.

   A binary file is a file stored in binary format. A binary file is computer-readable but not human-readable. All executable programs are stored in binary files, as are most numeric data files.

   The binary file is the most common type of computer file, and it can be found on all types of computers, including Windows PCs, Macs, Linux systems, and mobile devices such as smartphones and tablets. Binary files are also known as executable files or object codes.

   The advantage of using binary files is that they can be sent over the Internet more quickly than text-based or other types of non-binary files.

   Steps To Run or Execute Binary (.bin) Files on Linux

   You can use the following methods to execute your “.bin” files:

   Run .bin Files Via CLI on Linux

   Those who are comfortable with the command line interface can use the following Linux Commands.

   When you have downloaded your binary file in your Linux distro, you need to change the permissions of the specific “.bin” file using the “chmod” command. For example:

   Execute .bin Files

   At this point, you can easily run your binary file by using the command below:

   This will run your downloaded binary file.

   Run .bin Files Via GUI on Linux

   Those who are comfortable with the graphical user interface can use the following steps.

   First, you need to open the directory where the desired “.bin” file is saved or downloaded on your Linux distro.

   Then, right-click on the file and choose the “Properties” option.

   The “Lato-Regular.bin Properties” window will be opened.

   From there choose the “Permission” icon located in the menu bar of the “properties” window. Tick the highlighted checkbox “Allow executing file as a program”.

   Finally, double-click on the “.bin” file and install it.

   Conclusion

   At this point, you have learned to Run or Execute Binary (.bin) Files on Linux.

   Hope you enjoy it. You may be like these articles too:
