Normally when you launch an application through the terminal, the standard output appears, and closing the terminal closes the application.
|

|
## Using `systemd`
|

a [blog post](https://www.ralismark.xyz/posts/systemd-run) they wrote on replacing `nohup` with `systemd-run`
|
|
|
|
|
|
To run a graphical application it's as easy as:
|
|
```bash
|
|
systemd-run --user application
|
|
```
|
|
|
|
If you want to see any of the application terminal output,
|
|
then when the service is running you can check the status
|
|
like any other systemd service.
|
|
```bash
|
|
systemd --user status application
|
|
```
|
|
|
|
Note that the current directory information is not known
|
|
to `systemd-run`. Therefore, if you'll need to specify
|
|
absolute as opposed to relative paths. For example:
|
|
```bash
|
|
systemd-run --user okular "$PWD/document.pdf"
|
|
```
|
|
|
|

## Using `nohup` (Legacy)
|
|
|
|
When the terminal closes, it sends a hangup signal to all of the processes it manages.
|
|
The `nohup` command allows applications to run regardless of any hangups sent.
|
|
Combine that with making it a background task,
|
|
and you have a quick and easy way to launch applications through the terminal.
|
|
|
|
```bash
|
|
nohup application > /dev/null &
|
|
```
