Note that the process remains even after logging out with SSH

Introduction

This is a memo on how to keep the process after logging out when connecting with SSH. Basically, you can do what you want to do.

$content of the nohup command> out.log &

Example

$ nohup echo "very very heavy task" > out.log &

Doing this will create a ʻout.log` file in the calendar directory and save the output.

out.log

very very heavy task

Functionalization

The main is from here. The previous command is a bit long, so register it as a function.

The shell I'm using is zsh, so add the following to ~ / .zshrc. For bash, add it to ~ / .bashrc.

.zshrc

background () {
    nohup ${@:1} > out.log &
}

Save the content and apply your changes.

$ source ~/.zshrc

You can now run it in the background by simply prefixing the process you want to run with background.

$ background echo "very very heavy task"

It doesn't matter how many arguments you have.

$ background python takes_many_args.py foo bar --arg3 1234 --arg4 abcd
