How to Run Programs Continuously with nohup on Linux
This guide explains how the nohup command lets you run Linux programs without hanging up, redirects output to nohup.out or a specified file, and provides common options and practical examples for background execution and output redirection.
nohup: Run Programs in Background
Function Description
nohup (short for “no hang up”) runs a program while ignoring hang‑up signals, so its output is not shown on the terminal.
Using nohup allows a command to continue after logging out, closing the terminal, or disconnecting. Output is appended to nohup.out in the current directory, or to $HOME if the file is not writable. If neither can be created, the command fails. When stderr is a terminal, it is redirected to the same file descriptor as stdout.
