Start command on ssh and access the progress of the command later.

The title say pretty much everything.
I have a headless debian pc. I use ssh with my laptop.
This is a example of what I want to do: start a download with wget with ssh. Leave home and when I come back, I want to see the progress bar of the download.
The perfect solution i think, it's something like vnc but it's the command line.

Thank you!

I hope you guys understand what i'm trying to say
French is my first langage, not english. Sorry for the mistakes

I am not quite sure I understand, but you can use redirection and the tee command. Like this:

Code:

wget https://www.gnu.org/software/bash/manual/bash.html 2>&1 | tee wget_out

The resulting file (wget_out) looks like this (pardon the Swedish!):

Code:

cat wget_out

You can also open up a screen session and run your wget inside of it.

Code:

$ screen -S wget_stuff
$ wget http://path/to/file

You can then disconnect from the screen session with "Ctrl+A D", or just close your ssh connection.

When you want to check the status, just reconnect to the screen session

Code:

screen -r wget_stuff
