Thanks farslayer. Wget, was my choice.
Ow, codes looks like chinese to me, too.
I'm not get used to the screen
But was solved. Assume myownuser as my own user,
. I created an "download-user" user with home path at /home/myownuser/downloads. Inserted myownuser and download-user on download-group. Corrected permissions, all files created/downloaded on download directory will be owned by all download-group.
Now mom only needs ctrl+alt+F1 to change to terminal, and type "start" or ctrl+c for start and stop my downloads.
I had a question related with this post, but for another thread.
EDIT: If someone know anything about my previous post, teach, please
EDIT: Finally I understood screen, I can close the terminal (!). Screen is the solution! Using it instead of the trash above.
