Screen

Screen is a program that lets you have many virtual console sessions in a machine. You may leave jobs running and then logout completely. Each jobs console output will be recovered later when you are back.

Ex.:

[guy@machine homedir]$ screen -S job1

(Nothing seems to happen, but in fact you are now in a virtual session. Do something that will take a long time and will produce console output.)

[guy@machine homedir]$ ls
caminhadas_bivaques.tex.backup  fratura1.eps                oito2.eps 
capacete.eps                    fratura2.eps                oito3.eps
capaealma.eps                   fratura3.eps                oitoduplo.eps
capa.eps                        fratura4.eps                oito.eps
[guy@machine homedir]$

(Now type <CTRL-A><CTRL-D>. The screen clears and...)

[guy@machine homedir]$ screen -S job1
[detached]
[guy@machine homedir]$

Now, whenever you want to recover that jobs output, you do

[guy@machine homedir]$ screen -R -S job1

and...

[guy@machine homedir]$ ls
caminhadas_bivaques.tex.backup  fratura1.eps                oito2.eps
capacete.eps                    fratura2.eps                oito3.eps       
capaealma.eps                   fratura3.eps                oitoduplo.eps
capa.eps                        fratura4.eps                oito.eps
[guy@machine homedir]$

Here we are again.
man screen is your friend.
Enjoy!
