How can I run a command from the terminal without blocking it?

I run a lot of programs in Ubuntu from the terminal, but I would like to be able to continue using the terminal after I have a program open. How can I put the programs in the background so that I don't have to open another window?

There are different ways to run a terminal program and continue using the terminal:

• You can open another terminal tab (right-click, then select "Open New Tab").
• You can append & to the command you run. Be aware that you will not see text output to the terminal, such as error messages.
• You can type Ctrl-Z and then run bg. This has the same effect as running command &
• You can run nohup command & and then press enter. (Thanks to ccpizza, see comments below.)

However, pressing Alt-F2 and then running your command from the GUI is usually considered best practice - there is no terminal at all!

Note that when using & (not nohup), closing the terminal will still terminate the application unless you run disown afterwards.

EDIT: It looks like using nohup will sometimes leave little droppings in your home folder. What would normally have been logged to the terminal is apparently saved to a file in ~/.

A simple way to run a program in the background is program-name & disown, which will drop you to a terminal which can be closed without killing the process.

You can use setsid to run program in a new session with addition to &>/dev/null so you will not receive any log messages.

So it would be like

setsid program-name &>/dev/null

You can run the command with a & after.

For example:

thunderbird &

Using screen command, you can open multiple terminal sessions using a single window

apt-get install screen (On Debian based Systems)

yum install screen (On RedHat based Systems)

screen (start new screen)

[Your command]

Ctrl+A d to leave screen ... and so on
