Have you read this article to the end? Congratulations! You now know how to redirect nohup output to a file in Linux. With this tutorial, you can keep your programs running in the background and store the output for future use. So why not give it a try? Redirect your nohup output to a file today!

Nohup is an effective tool to run commands in the background even after a user logs out of a session. It is a Unix command that helps to execute a script or command without the need to log out of the session. By default, the output of a command executed using nohup is stored in a file with the name nohup.out. However, the output can be redirected to any other file using the redirection operator. In this tutorial, we will discuss how to redirect the output of nohup to a file.

Prerequisites

To perform the steps in this tutorial, you will need:

• A Linux-based operating system with a terminal window.
• A user account with sudo privileges.

Redirecting Nohup Output to a File

To redirect the output of nohup to a file, use the following syntax:

nohup command > output.file 2>&1

Let’s break down the syntax of this command:

• nohup: This is the command used to execute a shell script or command in the background.
• command: This is the command or shell script that you want to run in the background.
• >output.file: This is the output redirection operator that redirects the standard output of the command to the specified file.
• 2>&1: This is the output redirection operator that redirects the standard error of the command to the same file as the standard output.

Example

To understand how the above command works, let’s look at a practical example. In this example, we will redirect the output of a command that prints the contents of the /etc/passwd file to a file named output.txt.

nohup cat /etc/passwd > output.txt 2>&1

This command will execute the cat command in the background and redirect its standard output and standard error to a file named output.txt.

In this tutorial, we learned how to redirect the output of nohup to a file. We discussed the syntax of the redirection operator and also looked at a practical example. To improve your coding skills, practice the steps in this tutorial as often as you can.
