What is the purpose of nohup in Linux?

The nohup command in Linux is used to run commands in the background without being affected by the user terminal being closed. Its purpose is to allow commands to continue running in the background, even if the user logs out or closes the terminal. The nohup command is primarily used for tasks that require a longer time to complete, such as running scripts, compiling programs, etc. By using the nohup command, tasks can be handed over to the operating system to be processed without being restricted by user logins and terminal closures.
