+# The `nohup` command
+
+When a shell exits (maybe while logging out of an SSH session), the HUP ('hang up') signal is send to all of its child processes, causing them to terminate. If you require a long-running process to continue after exiting shell, you'll need the `nohup` command. Prefixing any command with `nohup` causes the command to become _immune_ to HUP signals. Additionally, STDIN is being ignored and all output gets redirected to local file `./nohup.out`.
+
+### Examples:
+
+1. Applying nohup to a long-running debian upgrade:
+
+```
+nohup apt-get -y upgrade
+```
+
+### Syntax:
+
+```
+nohup COMMAND [ARG]...
+nohup OPTION
+```
