How do I start a command from terminal so that terminal is not the parent?

Question

Let's take example of a command "example-command".

1. I open terminal
2. I write example-command in terminal, and example-command executes.
3. Now if I close terminal, example-command gets killed too.
4. I now try with "example-command &", but the same behaviour.

How do I execute a command so that when I close the terminal, the command doesn't get terminated?

Answer 1

There are two ways, identical in result.

1. Use nohup when you start your program. E.g., nohup example-command. You can background and work with it normally; it will simply continue running after you've quit.
2. Alternatively, as @alamar noted, if you use bash as your shell, you can us the disown command. Unfortunately, as far as I know, disown is bash-specific; if you use another shell, such tcsh, you may be restricted to the nohup form above.
