Guide: How to Run a Binary File in Linux Easily

ByMark Posted on

Running a binary file in Linux is a fundamental skill that can unlock a multitude of possibilities, and in this guide, I will show you how to do it easily.

Key Takeaways:

  • Understanding file permissions is crucial when running a binary file in Linux.
  • You can make a binary file executable in Linux through the user interface or the terminal.
  • Using the “chmod +x” command in the terminal allows you to make a binary file executable.
  • The “./” command is used to execute a binary file in the terminal.
  • Some binary files may require root privileges to install or run in Linux.

Understanding File Permissions in Linux

Before running a binary file in Linux, it’s essential to understand how file permissions work and how they can be adjusted to allow execution. File permissions in Linux determine who can read, write, or execute a file. The three main categories of file permissions are owner, group, and others.

To view the permissions of a file, you can use the

1
ls -l

command in the terminal. The output will display a series of characters indicating the permissions for the file. Each permission is represented by a letter:

1
r

for read,

1
w

for write, and

1
x

for execute.

To modify file permissions, you can use the

1
chmod

command. For example, to make a file executable, you can use the command

1
chmod +x filename

. This grants execution rights to the file for the owner, group, and others. If you want to limit the execution permission to just the owner, you can use

1
chmod u+x filename

.

Permission Symbolic Numeric
Read r 4
Write w 2
Execute x 1

“Understanding file permissions is crucial when it comes to running binary files in Linux. By carefully adjusting the permissions, you can control who can execute the file. Always remember to use caution when granting execute permissions to ensure the security of your system.”

Making a Binary File Executable in Linux

To run a binary file in Linux, it must first be made executable, and I’ll walk you through the process using both the graphical interface and the command line.

In the graphical interface, you can right-click on the binary file and select “Properties.” Then, navigate to the “Permissions” tab and check the box that says “Allow executing file as program.” This will make the file executable, and you can now double-click on it to launch it.

If you prefer using the command line, open a terminal and navigate to the directory where the binary file is located. Use the

1
chmod +x

command followed by the name of the file. For example, if your file is named “binaryfile”, the command would be

1
chmod +x binaryfile

. This command grants executable permissions to the file.

Once the file is executable, you can then run it by typing

1
./binaryfile

in the terminal. The

1
./

is necessary to specify that the file should be executed from the current directory. If the file requires elevated privileges, you may need to use

  2. In the graphical interface, right-click on the file, go to “Properties,” and enable the “Allow executing file as program” option.
  3. In the command line, use the
    1
    chmod +x

    command followed by the file name to grant executable permissions.

  4. After making the file executable, you can run it using
    1
    ./binaryfile

    command in the terminal.

In conclusion, running a binary file in Linux requires making it executable first. Whether you choose to use the graphical interface or the command line, the process is straightforward. Just follow the steps outlined above, and you’ll be able to launch your binary files with ease.

Command Description
1
chmod +x filename

Running a Binary File in Linux through the Terminal

The terminal offers powerful options for running binary files in Linux, and I’ll guide you through the process of making a file executable and executing it using simple commands. To start, you’ll need to change the file permissions to make it executable. This can be done using the

1
chmod +x

command followed by the file name. For example, if your binary file is named “program”, you would type

1
chmod +x program

in the terminal. This command grants the execute permission to the owner of the file.

Once the file is executable, you can execute it by using the

1
./

command followed by the file name. Continuing with the previous example, you would type

1
./program

in the terminal. The file will be executed and its output will be displayed in the terminal window. If the binary file requires elevated privileges to run, you can use the

1
sudo

command before the execution command. This will prompt you to enter your password and run the file as the root user.

It’s important to note that running binary files through the terminal gives you more control and flexibility. You can pass command-line arguments to the file, redirect input and output, and even schedule it to run at specific times using cron jobs. The terminal is a powerful tool for running binary files and exploring the capabilities of Linux.
